Section 1: General

The CS 5 is a fully modular, highly flexible conference system. Using Ethernet technology, it provides maximum secu-

rity and excellent digital audio quality. The CS 5 components can be used for any conference system from simple se-

tups to the most complex systems including ID card identification; three-way voting or five-way polling; interpretation

of up to 63 languages; and infrared transmission of up to seven languages. The CS 5 is extremely easy to wire, pro-

gram, set up, and expand.

All microphone stations are connected to the CS5 BU Base Stration in a closed-circuit Ethernet configuration so even

if one component fails, all other microphone stations will remain functional. The Base Unit also provides all the circuitry

required to drive the CS5 IRT1 and CS5 IRT2 infrared radiators. The CS5 IRR7 infrared receivers provide seven selec-

table language channels. In addition, the CS5 BU contains interfaces for a range of external devices including mixers,

wireless microphone systems, recording devices, CD players, etc.

The system provides 64 audio channels (0 - 63) that can be assigned as required to delegate, chairperson, or inter-

preter stations. Channel 0 is permanently assigned as the floor channel (sum of all microphone stations, external mi-

crophones (unless routed otherwise) and line inputs). Channels 0-6 are routed to the infrared outputs. Channels 0-3

are available at the headphone outputs on the CS5 DU microphone station. Channels 0-63 are available at the head-

phone outputs on the CS5 VU microphone station.

Important:

•

To avoid malfunctioning due to conflicting signals, use only a single CS5 BU Base Unit in any CS5 con-

ference system.

•

To avoid data loss or corruption, malfunctioning, or damage to the system, never make any changes

to the wiring or operate any control on any system component, or disconnect the system from power

while a software update is in progress.

Note:

•

For instructions on setting up your CS 5 Conference System from wiring to powering up, refer to the "Getting

ꢀ

Started Quickly" guide that you should have received together with your shipment. If the "Getting Started Quickly"

guide or any other component is missing, contact your AKG Distributor immediately.

•

This User Manual contains detailed information on how to set up each CS 5 component.

Section 2: Notes on Wiring and System Examples

2.1 Notes on Wiring and System Configuration

Important:

1. Never connect your CS5 MK.. LAN cables to any equipment (desktop or notebook computers, etc.) other

than CS 5 system components. The LAN cables will carry a 48 V supply voltage that may damage equip-

ment not designed for such voltages.

2. Make all audio and LAN cable connections before connecting any Conference System component to

power.

3. To avoid damage to any system component, do not lay, connect, or disconnect any cables while power

to the system is on. Always disconnect the entire system from power before making any changes to

the wiring.

4. To avoid interference problems, make sure that all audio cables you are going to connect to the Base

Unit audio outputs are shorter than 10 feet (3 m).

5. Note that the CS 5 BU Base Unit will not function with no microphone stations connected to it (no mat-

ter what other equipment you may have connected to the Base Unit). Therefore, make sure always to

connect at least one CS 5 VU or CS 5 DU microphone station to the Base Unit to set up a functional

CS 5 system.

•

Route power cables so that nobody may trip over them or step on them. A cable getting disconnected by some-

body tripping over it may cause system malfunctioning or damage to system components.

To avoid hum problems, do not route audio or LAN cables close to power cables.

In permanent installations, use separate ducts for power and audio/LAN cables.

While LAN cables may be as long as 164 feet (50 m) without degrading system performance, keep all other ca-

bles as short as possible to keep cable attenuation to a practical minimum. Check that all audio cables connected

to the Base Unit are shorter than 10 feet (3 m).

•

Always connect all microphone stations in any system to the Base Unit in a closed loop. Use CS5 MK.. LAN cables

to daisy-chain all microphone stations from one SYSTEM connector on the Base Unit back to the other SYSTEM

connector on the Base Unit. This ensures that if one of the LAN cables breaks all microphone stations will remain

operative.

Example 2: Larger discussion system with computer control.

Example 2 above shows a larger discussion system with more than six microphone stations and computer control. To

ensure stable powering even if one power supply fails, connect one CS 5 PS 12 power supply to the Base Unit, one

CS 5 PS 12 power supply to every sixth microphone station, beginning with the seventh in line counting from the Base

Unit, and connect the last microphone station to the second SYSTEM connector on the Base Unit.

The computer controlling the system is connected to the USB port on the Base Unit. In order to make optimum use of

all the functions offered by computer control, we recommend using CS 5 VU microphone stations, although computer

control will also work with CS 5 DU stations.

•

Dip switches S1 to S4 route the LINE, EXT. MIC., TAPE, and SYSTEM inputs to either the NORMAL or EFFECTS bus.

The NORMAL bus feeds the mixed input signals to the TAPE, LINE, SYSTEM, , and INFRA outputs.

The EFFECTS bus signal is available at the EFFECT output where you can connect a feedback eliminator or other

effects device. Connect the output of your effects device to the EFFECT IN jack on the rear panel. The processed

signal is fed to the NORMAL bus. As long as no effects device is connected, the signal is routed to the NORMAL

bus.

•

Dip switches S5 and S6 let you activate and deactivate NOM attenuation. NOM (Number of Open Microphones) at-

tenuation reduces the volume of the loudspeakers in a sound system depending on the number of microphones

that are active at any time. The more microphones are open, the more the loudspeaker volume is reduced. S5 al-

lows you to activate NOM attenuation for the loudspeakers on the microphone stations connected to SYSTEM out-

puts. S6 lets you activate NOM attenuation on the LINE OUT signal that feed the room sound system.

Dip switch S7 allows you to select the input signal for system channel 1. To route the assigned Interpreter Station

output to channel 1, set S7 to "0". To route the EXT. LANG. input to channel 1, set S7 to "1". You can use the lat-

ter configuration for a consecutive interpreter with a hardwire or wireless microphone.

•

Dip switch S8 selects one of two microphone activation modes.

With S8 in position "0", a microphone will be switched on immediately on pressing the talk button ("requesting the

floor") if a microphone channel is available. If no microphone channel is available, the microphone requesting the

floor will be put on the waiting list.

With S8 in position "1", a microphone will be switched on immediately on pressing the talk button if a microphone

channel is available. If no microphone channel is available, the floor request on top of the waiting list will be deleted

and the last microphone requesting the floor will be added to the waiting list.

3.4.3 Selecting NOM Limitation/Interpretation Channels

•

Set NOM LIMIT (7) to the desired ratio between the maximum number of microphones that may be open at any

time and the number of channels available for interpretation.

If no interpretation is needed, you may set NOM LIMIT to "64/0", allowing 64 microphones to be open simultane-

ously. To reduce the number of open microphones, set NOM LIMIT to a lower position.

If interpretation will be provided, set NOM LIMIT for the number of interpretation channels required (e.g., "48/16"

for any number of interpretation channels up to 16 and 48 open microphones).

1. Set up all microphone stations referring to section 4 (page 18) and make all power connections.

2. Switch power to the Base Unit ON, wait for five seconds, switch the first twenty microphone stations ON, wait for

five seconds, switch the next twenty microphone stations ON, and so on.

Important:

•

To avoid overloading your power line and causing a risk of fire when powering up, make sure never to

connect more than twenty microphone stations to a common circuit with a common power switch and

never switch more than twenty microphone stations ON at a time.

Systems with one or more CS 5 VU Microphone Stations

Important:

•

When powering up for the first time or after making any changes to the system configuration, it is ab-

solutely necessary to run the “LEARNING” routine by following steps 3 through 5 below. Failing to do

so will cause severe system malfunctioning!

3. Insert the SERVICE CARD supplied with the Base Unit into the card slot on any CS 5 VU microphone station.

4. Press soft buttons 1 and 5 simultaneously on the same microphone station into which you inserted the SERVICE

CARD.

5. As soon as the display reads “LEARNING SUCCEEDED”, remove the SERVICE CARD. The Base Unit has now stored

the system configuration and will load this configuration immediately after switching power ON the next time.

If you are not sure if the “LEARNING” routine has been run, run it again. This will cause no problem.

Important:

•

Mark the SERVICE CARD clearly and unmistakably and keep it in a safe place. You will need to use it

every time you power up a newly set up mobile system for the first time and every time you made any

change to an existing (mobile or permanently installed) system configuration.

Note:

If you lose your SERVICE CARD, order a replacement from your AKG Distributor.

•

ꢀ

Alternatively, you can program your own SERVICE CARD by changing the number of an existing chip card to “0”.

Refer to the Software Manual for information on how to program chip card numers.

Systems with CS 5 DU Microphone Stations only

System configurations with CS 5 DU stations only cannot be stored in memory. To power up such a system, sim-

ply follow steps 1 and 2 above.

•

3.4.5 Setting Levels

1. Set up all microphone stations referring to section 4, make all power connections and switch power to the Base

Unit and all ancillary equipment ON. (Steps 5 through 9 in the Getting Started Quickly manual.)

2. Have people talk into the microphones on the microphone stations. You can set the SYSTEM control to maximum

without risking to overload the amplifier input.

3. You can set the level controls (INPUTS ADJUST) for all other inputs you will use to maximum without risking to over-

load the amplifier input.

4. Set the level controls for all unused inputs to minimum.

5. Use the SPEAKERS control (8) to set the volume level for the loudspeakers on the microphone stations just high

enough to get optimum intelligibility. Do not set SPEAKERS higher than to the point where the red Peak LED of the

bargraph (9) will only flicker occasionally. Excessive levels may cause audible distortion.

6. Use the MAIN control (10) to set the volume level for the room sound system just high enough to get optimum in-

telligibility and avoid feedback. Do not set MAIN higher than to the point where the red Peak LED of the bargraph

(11) will only flicker occasionally. Excessive levels may cause audible distortion.

7. Connect a pair of headphones to the jack on the front panel for monitoring the main mix on the NORMAL bus.

3-4 Volume control buttons: The UP button (4) increases and the DOWN button (3) decreases the volume of the built-

in speakers or headphones connected to the microphone station.

• If no headphones are connected to the microphone station, the volume control buttons set the volume of the

built-in loudspeakers.

• If a single pair of headphones is connected to either headphone jack, the volume control buttons set the vol-

ume for that pair of headphones.

• If headphones are connected to both headphone jacks, the volume control buttons set the volume of both head-

phone channels.

Note: When the microphone is open, the volume of the loudspeakers will be attenuated by a specific amount de-

pending on the polar pattern of the microphone used. The headphones volume will not be affected.

station.

The settings of S1-S2 determine the frequency response and gain of the audio section as well as the amount of

gain reduction that is applied to the loudspeaker amplifier as soon as the microphone opens.Therefore, microphone

stations with unidirectional microphone capsules allow delegates to hear other talkers on the built-in loudspeak-

ers even while the microphone is open.

Section 5: CS5 VU Voting/Chairperson Station

5.1 Introduction

The CS5 VU can be configured either as a delegate station with a voting function or as a chairperson station with vot-

ing and priority functions. Like the CS5 DU, it provides a microphone connection, talk button, two built-in loudspeak-

ers, and two headphone jacks.

The loudspeakers reproduce the main mix ("floor signal") while the headphone jacks allow the user to listen to the floor

signal or one of 63 interpreted languages.

In addition, the CS 5 VU incorporates a chip card reader for user identification by conference control software. A liquid-

crystal display and five soft buttons allow the user to call the meeting to order, initiate ballots, cast their vote, select lan-

guages for the headphone outputs, etc.

5.5 Chip Card Identification

Chip card identification is only available in a computer controlled system and the identification system only accepts AKG

chip cards. The chip card reader and control software check the identity of the person using the microphone station as

well as their priority and voting rights, allowing votes to be weighted or classified. This system also allows holders of

AKG chip cards to exercise their rights not only from their assigned microphone stations, but from any CS 5 VU micro-

phone station in the conference system.

Note: To assign chip cards to persons, enter each person's data into the database in the CS 5 ConferControl soft-

ware. For details, refer to the ConferControl Operating Manual.

ꢀ

• Instruct users how to identify themselves to the system:

1. Insert the chip card into the chip card reader slot with the contacts pointing toward the slot as shown on the dis-

play:

The main menu appears on the display.

If you inserted the card the wrong way, or if you inserted an incompatible card, a warning message ("WRONG

CARD") will appear on the display:

Important:

•

Inserting any card other than an AKG chip card causes malfunctioning and may even damage the card

or the equipment.

2. Remove the chip card by the time the session is over.

Note: If two persons share a single CS5 VU, both persons can vote by taking turns using their chip cards and pro-

ceeding as describe in sections 5.4 and 5.5 above.

Section 6: CS 5 IU Interpreter Station

Refer to

fig. 8

on page 29.

10 Loudspeaker: The loudspeaker is automatically muted when a pair of headphones is connected to the headphone

output (18).

When no headphones are connected to the Interpreter Station, the loudspeaker reproduces the selected incoming

signal. The rotary controls (6), (7), and (8) adjust the loudspeaker signal.

OUTPUT SELECT: These keys select one of two pre-selected target language channels and allow the interpreter to re-

quest the talker to speak more slowly or to call a technician for assistance (provided a technician is available).

11 A: Routes the microphone signal to the target-language channel specified for this booth.

12 CALL: This key has two functions:

• Pressing <CALL> momentarily sends a "speak slowly" signal to the talker. The red LED above the <CALL>

key and the green LED on the microphone arm of the talker's Delegate Station will flash for about 5 seconds.

The display (5) shows the message "SENDING SLOWLY PLEASE". Pressing <CALL> momentarily again before

the five seconds have elapsed will stop the signal.

• Holding down <CALL> for at least 3 seconds activates an appropriate message on the computer monitor

alerting the technician that an interpreter needs assistance. To cancel the signal, hold down <CALL> again for

about 3 seconds.

13 B: Routes the microphone signal to the source-language channel specified for this booth.

14 MICROPHONE: This toggle switch provides three positions:

• OFF: The microphone is off and the LED on the microphone arm is dark.

• ON: The microphone is open and the LED on the microphone arm is lit.

• MUTE (cough button function): The microphone is muted and the LED on the microphone arm is dark for as

long as you hold the switch in the MUTE position. The switch will return to the ON (center) position as soon as

you release the switch.

15 Microphone input.

16 External microphone input: This mini jack allows you to connect the microphone of a headset if the client spec-

ifies headsets for the interpreters instead of microphone arms and separate headphones.

17 System port: RJ45 connector for CS5 MK.. LAN cables. (Refer to section 2.2 for example wiring diagrams.)

: Mini jack for stereo headphones.

6.3 Setting Up

Important:

•

According to international practice as specified by the AIIC, each interpretation booth must provide

two Interpreter Stations because interpreters never work alone. Having an interpreter work alone in a

booth would be unethical.

Note: In the following sections, the terms "source language", "target language", and "relay language" will be used

frequently.

ꢀ

The source language is the language an interpreter translates into another language. That other language is

called the target language.

A relay language is a target language that is used as a source language by another interpreter if that inter-

preter is not qualified to interpret the original source language.

6.3.1 Making Connections

1. Screw the microphone capsule on the gooseneck.

2. Screw the gooseneck into the microphone input.

3. Use the appropriate CS5 MK.. cables to connect the system ports on the microphone station to the system ports

on the preceding and subsequent microphone stations.

nel 2 -> French, etc.).

•

Assign each of these channel numbers to one interpretation booth (e.g. booth no. 1 -> English, booth no. 2 ->

French, etc.).

If a relay language has been specified, assign a channel number to the relay language. Invariably, the relay lan-

guage will be identical to one of the target languages.

Route output A on each Interpreter Station in the same booth to the same language channel (e.g., select channel

1 (English) for output A on each Interpreter Station in booth 1, channel 2 (French) for output A on each Interpreter

Station in booth 2, etc.)

Route output B on each Interpreter Station in each booth to the language channel number assigned to the relay

language (e.g., channel 3 for Italian).

Section 6: CS 5 IU Interpreter Station

6.4 Using the Interpreter Station

Important:

•

Before powering the system up, set the MICROPHONE switch on each Interpreter Station to "OFF" to

avoid "broadcasting" any unofficial conversations.

Upon system power-up,

•

the display shows the message "SYSTEM STARTING…" until synchronization is completed. Once synchronization

is finished, the display shows the main menu.

•

the microphone input is automatically routed to output A and the red LED above OUTPUT SELECT key <A> is lit.

The microphone will be open only if the MICROPHONE switch is in its center position ("ON"). When the micro-

phone is open, the red LED on the microphone arm will be lit.

•

if the MICROPHONE switches on both Interpreter Stations are in their "ON" positions, the microphone on the In-

terpreter Station with the lower (odd) address will be opened. The microphone on the Interpreter Station with the

higher (even) address will be muted. On the active Interpreter Station, the red LED above the active OUTPUT SE-

LECT key and the red LED on the microphone arm will be lit, while the corresponding LEDs on the other Interpreter

Station will remain dark.

Instruct the interpreters how to use the Interpreter Stations:

1. Select your source language:

• If the person using the floor microphone speaks your source language, press <FLOOR>. You will hear the floor

talker on your headphones and the display shows the message "FLOOR".

• If you need your colleagues' relay, press <RELAY>. On your headphones, you will hear the voice of the inter-

preter working into the relay language. The display shows the message "RELAY".

The microphone signal will be automatically routed to output A.

• To select one of the other available source languages, press <INPUT/A> or <INPUT/B>. You will hear the se-

lected language on your headphones and the display indicates the selected language".

2. Use the VOLUME, BASS, and TREBLE controls to adjust the headphone volume and sound for optimum intelligibility.

These controls also set the volume and sound of the loudspeaker on the Interpreter Station.

3. Select your target language:

• To interpret from the floor language (e.g., English) into your booth's target language (e.g., Portuguese), check

that output A is selected (the red LED above the OUTPUT SELECT <A> key is lit). If it is not, press <A>.

• If a speaker of your booth's target language (e.g., Portuguese) takes the floor and you are required to interpret

into the relay language (e.g., English), press <B> to select output B. The red LED above the OUTPUT SELECT

<B> key is lit and the headphones are automatically switched to the floor channel.

(Tech note: The floor channel is automatically fed to the language channel selected for output A to save dele-

gates the trouble of having to switch their headphones to the floor channel.)

Note: Pressing an OUTPUT SELECT key on one control panel will route the other control panel (which becomes a

"slave" to the first panel) in the booth to the same output channel. The appropriate LED on the "slave" control

panel will be lit accordingly.

ꢀ

4. Controlling the microphones:

• The interpreter who agreed to begin opens their microphone by setting the MICROPHONE switch to "ON" and

the other interpreter switches their microphone OFF (unless it is off already). The red LED on the open micro-

phone and the red LED above the active OUTPUT SELECT key are lit.

Important:

•

Make sure never to switch both microphones in your booth ON simultaneously. If you do, only one mi-

crophone will be activated and the other muted automatically, so the wrong microphone may come on.

• When it is time to relieve your colleague, you can do so in one of two ways:

- Method 1: the interpreter on duty switches their microphone OFF (the red LED on the microphone goes out)

and the other interpreter switches their microphone ON (the red LED on the microphone comes on).

- Method 2: the interpreter taking over presses the appropriate OUTPUT SELECT key. The red LED on the micro-

phone comes on, the relieved colleague's microphone is automatically muted, and the red LED on that micro-

phone goes dark.

Note that when using this method, one microphone will always be open. To make sure your listeners will not hear

any of your internal conversations, always set the MICROPHONE switches on both control panels to OFF when

none of you is interpreting.

5. Controlling talkers:

• If the person delivering a speech talks too fast, press <CALL> momentarily. This causes the green LED on the

microphone arm on the talker's Delegate Unit to flash for five seconds. The display on your control panel shows

the message "SENDING SLOWLY PLEASE". To stop the signal before the five seconds are over, press <CALL>

again.

6. Calling a technician (if the system is computer controlled and a technician is available):

• If there is a technical problem or you have run out of water, etc. hold down <CALL> for at least three seconds.

This causes an appropriate message to appear on the computer monitor and the message "CALLING TECHNI-

CIAN" to appear on your control panel display.To delete the messages, press and hold <CALL> again for at least

three seconds.

Section 7: Infrared Transmission System

7.1 CS 5 IRT 1 and CS 5 IRT 2 Infrared Radiators

7.1.1 General

The CS 5 IRT 1 and CS 5 IRT 2 infrared radiators are capable of transmitting seven interpretation channels to the

CS 5 IRR 7 infrared receivers. The two radiator models are technically identical, except that the CS 5 IRT 2 is larger

than and provides about twice the radiation range of the CS 5 IRT 1.

Each infrared radiator comes complete with a mounting bracket for installation on a wall or ceiling.

Fig. 9: CS 5 IRT 1 and CS 5 IRT 2 front views.

Fig. 9a: CS 5 IRT 1/CS 5 IRT 2 bottom panel.

Green OPERATE LED: The green OPERATE LED is lit to indicate that signal is being radiated.

Yellow OPERATE LED: The yellow OPERATE LED is lit to indicate that the infrared driver circuitry is in standby mode.

MAINS: This red LED is lit to indicate that power to the radiator is ON.

IREDs

IN: BNC input connector for the PPM modulated time-multiplexed signal driving the IREDs (infrared emitting diodes)

(7).

Refer to

fig. 9a.

OUT: This BNC output connector is connected in parallel to the IN connector allowing you to daisy-chain several

infrared radiators.

Power input: Standard IEC power connector for 230 V/50 Hz.

7.1.2 Placement

•

Basically, it is best to place the infrared radiators as close as possible to the area where the receivers will be used

and as high above the floor as practical. Diagram 1 in the Quickstart Manual shows an example of two infrared ra-

diators covering the delegates' tables only.

Section 7: Infrared Transmission System

•

To cover an entire room, place one infrared radiator in each corner of the conference room, at least 10 feet (3 m)

above the floor, aligning the front panel to face the opposite corner.

Walls and/or ceilings that are painted a dark color, paneled, or acoustically treated will absorb more infrared radi-

ation than white surfaces, so you will need more infrared radiators in darker rooms.

•

Sunlight, fluorescent lighting, and photo flashes may weaken infrared radiation. Therefore, try to place the infrared

radiators where they will not be exposed to natural or artificial light or use some extra IRTs.

Note: Working out the exact number of infrared radiators needed for optimum room coverage and placing them cor-

rectly can be a challenge in some rooms. As a rule of thumb, it is better to use many small (CS 5 IRT 1) radia-

tors than only a few large ones (CS 5 IRT 2). If you need assistance, your dealer or nearest AKG Distributor will

be glad to help.

ꢀ

7.1.3 Mounting

•

For mobile use, you can fix the support frame of the infrared radiator on a heavy standard loudspeaker stand.

•

For permanent installations, you can directly screw the support frame on a wall or ceiling at any desired angle. To

mount a radiator in a corner, you may need additional angle brackets (available from hardware stores).

•

To set the tilt angle of the radiator, slacken the set screws on the support frame, rotate the radiator to the desired

angle, and tighten the set screws.

7.1.4 Connections

Important: To avoid damage to any system components, do not lay, connect, or disconnect any cables while power to

the system is on. Always disconnect the entire system from power before making any changes to the wiring.

1. Use RG58 50-ohm coaxial cable and BNC connectors to connect one INFRA OUT jack on the Base Unit rear panel

to the IN BNC jack on the infrared radiator on the left side of the room.

2. Use a cable of the same length (or as nearly as possible) to connect the other INFRA OUT jack on the Base Unit

rear panel to the IN BNC jack on the infrared radiator on the right side of the room.

3. If you need to use more than one radiator on either bus, use RG58 50-ohm coaxial cable and BNC connectors to

connect the OUT jack on the first radiator to the IN jack on the subsequent radiator, and so on.

Note: To ensure consistent performance of the two radiators, keep the difference in length between the two cables

to a practical minimum (less than 164 feet/50 m).

ꢀ

4. Connect each infrared radiator to power.

The CS 5 IRT 1 and CS 5 IRT 2 infrared radiators have no power switches. Therefore, connect the power input on

each radiator to a switched 230 V/50 Hz power outlet protected by an appropriate fuse.

Important:

•

If no switched power outlets are available at the site of a permanent installation, ask a qualified elec-

trician to install the required number of outlets in the conference room and a suitable ON/OFF switch

in the control room in accordance with local electrical and occupational safety regulations.

provided by the organizers (or by ear, if no such list is available).

4. Use the VOLUME control (5) to set the volume level of your headphones just loud enough so you can hear clearly

what is being said.

Important:

•

Do not turn the headphones volume up any higher than necessary. Listening to excessive sound lev-

els on headphones may damage your hearing.

(Refer to fig. 10 on page 37.) Never cover the collecting lens (4) above the infrared receiving diode. Cov-

ering the lens (4) will cut the signal and may cause the receiver to switch off automatically.

•

Note: The signal may fade in some spots within the conference room due to interference or shadow effects. If that

happens, move away from such a spot.

ꢀ

5. If the BATTERY LED (3) on the receiver top panel starts flashing, the battery will be dead soon. Return the receiver

to conference staff. They will give you a receiver with a fully charged battery.

6. You cannot switch power to the receiver off.The receiver will switch off automatically 30 seconds after the infrared

signal has stopped.

Note: The receiver will also switch off automatically before the battery is completely discharged to avoid damaging

the battery.

7.3 CS 5 CU 50 Charger/Storage Case

7.3.1 General

The CS 5 CU 50 is a combined charger and transport/storage unit in a rugged, lockable flight case. It allows you to store

up to 50 CS 5 IRR 7 infrared receivers during a conference and charge the batteries inside them. Each charging slot

has its own independent charging control circuit.

Fig. 11: CS 5 CU 50 control panel and charging slots.

DC 15V 4.6A: Input connector for the DC cable of the supplied dedicated power supply. The power supply oper-

ates on any voltage from 100 to 240 VAC.

FUSE: 5 A, fast-blow fuse.

POWER: This red LED is lit to indicate that power to the charger is ON.

Charging slot for charging the battery inside a receiver. The charger provides 50 charging slots.

7.3.2 Charging Batteries

1. Unlock and remove the lid from the flight case.

Refer to

2. Connect the DC cable on the supplied AC adapter to the DC 15V 4.6A jack on the CS 5 CU 50 charger.

3. Connect the AC adapter to a convenient power outlet.

fig. 11above.

Important:

•

To avoid any risk of damage, do not use any power supply other than the AC adapter included with the

charger.

To avoid any risk of damage, fire, or explosion, never insert a receiver with dry (non-rechargeable) bat-

teries inside into any charging slot.

•

4. Insert each receiver whose battery needs charging (BATTERY LED flashing) into a charging slot (4) with the charg-

ing contacts facing the bottom of the charging slot.

Charging will start automatically and the BATTERY LED on the receiver will be lit red constantly.

As soon as the battery is charged to capacity, the BATTERY LED on the receiver will start flashing red to indicate

the battery is being trickle-charged.

5. Remove the receiver from the charging slot.

Note: Charging time depends on battery capacity. It is approximately four hours for a 280 mAh 9 V NiMH recharge-

able battery.

ꢀ

7.3.3 Battery Care

1. Always store the batteries inside the receivers in charged condition. Storing rechargeable batteries uncharged

would significantly reduce their useful life.

2. If you do not use a receiver for a long period of time, charge its battery to capacity every one or two months, no

matter to what level the battery has been charged before. This is important because the battery will self-discharge

even when the receiver is switched off.

3. Do not store receivers in trickle-charging mode in the CU 50 indefinitely. This may reduce the usfeul life of the bat-

tery inside the receiver. After a conference has ended, charge all receivers to capacity and switch power to the

CU 50 off.
