Limited Warranty  
Toshiba America Information Systems, Inc., (“TAIS”) warrants that this voice processing equipment (except for fuses, lamps, and  
other consumables) will, upon delivery by TAIS or an authorized TAIS dealer to a retail customer in new condition, be free from  
defects in material and workmanship for twenty-four (24) months after delivery. This warranty is void (a) if the equipment is used  
under other than normal use and maintenance conditions, (b) if the equipment is modified or altered, unless the modification or  
alteration is expressly authorized by TAIS, (c) if the equipment is subject to abuse, neglect, lightning, electrical fault, or accident,  
(d) if the equipment is repaired by someone other than TAIS or an authorized TAIS dealer, (e) if the equipment’s serial number is  
defaced or missing, or (f) if the equipment is installed or used in combination or in assembly with products not supplied by TAIS  
and which are not compatible or are of inferior quality, design, or performance.  
The sole obligation of TAIS or Toshiba Corporation under this warranty, or under any other legal obligation with respect to the  
equipment, is the repair or replacement by TAIS or its authorized dealer of such defective or missing parts as are causing the  
malfunction with new or refurbished parts (at their option). If TAIS or one of its authorized dealers does not replace or repair such  
parts, the retail customer’s sole remedy will be a refund of the price charged by TAIS to its dealers for such parts as are proven to  
be defective, and which are returned to TAIS through one of its authorized dealers within the warranty period and no later than  
thirty (30) days after such malfunction, whichever first occurs.  
Under no circumstances will the retail customer or any user or dealer or other person be entitled to any direct, special, indirect,  
consequential, or exemplary damages, for breach of contract, tort, or otherwise. Under no circumstances will any such person be  
entitled to any sum greater than the purchase price paid for the item of equipment that is malfunctioning.  
To obtain service under this warranty, the retail customer must bring the malfunction of the machine to the attention of one of  
TAIS’ authorized dealers within the twenty-four (24) month period and no later than thirty (30) days after such malfunction,  
whichever first occurs. Failure to bring the malfunction to the attention of an authorized TAIS dealer within the prescribed time  
results in the customer being not entitled to warranty service.  
THERE ARE NO OTHER WARRANTIES FROM EITHER TOSHIBA AMERICA INFORMATION SYSTEMS, INC., OR  
TOSHIBA CORPORATION WHICH EXTEND BEYOND THE FACE OF THIS WARRANTY. ALL OTHER WARRANTIES,  
EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR  
PURPOSE, AND FITNESS FOR USE, ARE EXCLUDED.

The Grand Tour  
1
This chapter familiarizes you with the Strata CTX DKT2204-CT and DKT2304-CT  
Cordless Digital Telephones (e.g., handset, batteries, base and charging units, fixed  
buttons). Chapter 4 – Feature Access Codes, beginning on page 37 covers the four  
pre-assigned flexible buttons.  
Your cordless digital telephone is engineered to work with your Toshiba digital  
telephone system and provide you with reliability, long life, and outstanding  
performance.  
The cordless digital telephone is compatible with all Strata CTX and Strata DK  
telephone systems (except Strata DK24/56/96, Release 3). All it requires for  
connection is a digital station port.  
Fully charged, your cordless digital telephone provides:  
DKT2204-CT: six hours of talk time and four days of standby time.  
DKT2304-CT: seven hours of talk time and five days of standby time.  
There is a fast charger in the handset and a trickle charger in the base.  
You can use your cordless as a stand-alone phone attached to a digital port, or in  
conjunction with a DKT3000/2000-series digital telephone—in which case both  
phones share the same digital port and extension number. You can switch between use  
of your DKT and your cordless, just by pressing a button.  
Note If using a DKT3000 digital telephone, it must be set to operate in DKT2000  
mode.

represents state-of-the-art design and engineering. The DKT2304-CT uses 900 MHz  
Digital Narrow Band technology. These technologies provide:  
Unsurpassed range, several times greater than conventional analog or cordless  
digital telephones.  
Clarity that is so good, it is indistinguishable from corded telephones in most  
environments.  
(DKT2204-CT) Fully secure communications for up to 10 cordless digital  
telephones within a given environment.  
(DKT2304-CT) Maximum security for up to 30 cordless digital telephones that is

Applications  
Applications  
Your cordless digital telephone brings mobility and productivity to office telephones.  
Greater call access cuts down on “telephone tag” delays. Its compact design makes it  
easy to take with you.  
Benefits  
Your cordless digital telephone uses advanced technology and provides important  
features that place it far above the competition in functionality and value. You benefit  
from much greater performance than other cordless telephones currently available.  
This means better sound quality, longer range, greater security, multi-line access,  
helpful LCD display information, and many other important advantages.  
The cordless digital telephone provides many advantages over a single-line analog or  
digital telephone. Some of those advantages are:  
Your cordless digital telephone has four flexible feature buttons. They have the  
same functions as the first four buttons on the 3000/2000-series desk DKT. If you  
do not use these buttons for the assigned features, you can invoke other features  
with access codes.  
Your cordless digital telephone rings to the same extension number as the regular  
DKT it is used with, enabling you to answer via either telephone. Both follow the  
same forwarding and hunting regardless of which telephone is in use. This is much  
simpler than having a separate extension number and standard station port for a  
single-line cordless.  
An SLT cordless is not only a cumbersome alternative to the Toshiba digital  
cordless; but also, if you forget to forward your calls, you cannot receive the calls  
on your SLT cordless. With your cordless digital telephone it is easy. Just press a  
button, grab your cordless, and go!  
A Message Waiting icon

appears on the LCD when message(s) are in the  
In addition to the benefits mentioned above, the DKT2204-CT also has the following  
benefits:  
Spread-spectrum technology provides five to seven times greater range than  
conventional cordless telephones, making your cordless digital telephone much  
more useful and valuable.

The Grand Tour  
Handset  
900 MHz spread-spectrum operation provides maximum security with a frequency  
range that is almost impossible to scan. Regular 900 MHz cordless digital  
telephones are difficult to scan, but less so than spread spectrum. Analog cordless  
telephone frequencies are easy to scan and provide virtually no security from the  
outside. Hackers and thieves can use this to hear conversations and pick up credit  
card numbers.  
Sound quality is better on your cordless digital telephone than non-spread  
spectrum 900 MHz digital cordless telephones. Sound quality on conventional  
analog cordless telephones is so poor by comparison that they are only practical for  
short range usage.  
Handset  
Your cordless handset has special function buttons (shown below) and an LCD that  
shows operating conditions.  
Note The handset and base unit of your cordless telephone is equipped with the same  
security code. In order for this handset to operate, it must be installed with the  
matching base unit.

Adding Voice Mail to a Conference  
Adding Voice Mail to a Conference  
The Conference Master can add voice mail to a conference. This enables participants  
in a conference to listen to or leave a voice mail message during a telephone call.  
To add Voice Mail to a conference call (performed by Conference Master)  
1. Press Cnf/Trn to place the current call on Consultation Hold.  
2. Dial the voice mail (VM) extension number, then enter the VM mailbox and  
security code. This adds the voice mailbox to the conference.  
3. Press Cnf/Trn to reconnect to the original party. (You can continue to add  
conference members by pressing Cnf/Trn and dialing another extension.)  
Now, all parties in the conference can listen to or record a message to this voice  
mailbox. Only the Master can control the VM with touchtones or Soft Keys.  
Connecting Two Outside Lines  
1. While talking on an outside call, press Cnf/Trn. You hear dial tone.  
2. Dial an outside line access code and outside telephone number.  
3. After the party answers, press Cnf/Trn. All parties are conferenced.  
If you receive a busy tone or if the station does not answer, press Cnf/Trn.  
4. Hang up. The two lines are connected.  
5. To supervise a tandem call, press Cnf/Trn. If the parties have finished, hang up or  
if the parties are still talking, press Cnf/Trn and hang-up. Both Line LEDs turn off  
and the connection is released.  
If your telephone company provides auto disconnect, the connection may release  
automatically when the parties hang up. If not, the lines must be supervised to be  
disconnected.

This chapter gives you all of the cordless digital telephone features in alphabetical  
order. Your cordless digital telephone provides many of the same features as a 2000-  
series corded digital telephone.  
In addition to the Msg, Hold, Cnf/Trn and Redial functions, your cordless digital  
telephone’s F1~F4 buttons perform the same way as the first four buttons on your  
3000- or 2000-series digital telephone. They are assigned during system installation.  
See your System Administrator for the features that have been assigned.  
If you are not using these buttons for the assigned features, you can invoke the  
features with access codes. Please see Table 3 below for access code sequences that  
match your Toshiba telephone system.

Troubleshooting  
Low Battery  
Your cordless telephone comes equipped with one rechargeable battery:  
DKT2204-CT: BT2499 battery that provides six hours of talk and four days of  
standby time (fully charged).  
DKT2304-CT: BT930 battery that provides seven hours of talk and five days of  
standby time (fully charged).  
A “fast charge” in the handset and a “trickle charge” in the charging unit enables the  
extended talk and standby times.  
When the battery is low, the Battery icon displays on  
the LCD (shown right) and the handset beeps. Low  
battery symptoms are:  
On a call  
All buttons and functions operate  
Handset beeps once every three seconds  
Note To continue your call, you must replace the battery pack within 20 seconds.  
In standby mode  
None of the buttons operate  
LCD messages are cleared  
Handset beeps every 15 seconds for three minutes  
To restore your battery capacity, return the handset to the charging unit for charging or  
replace the handset battery with a charged one. If the handset is on the charging unit  
for one minute, battery low condition is cancelled. The Battery icon is turned Off and  
battery low tone stops.  
For more information on installing and charging the battery, see Step 8: “Install  
Handset Battery Pack” on page 23.

Cleaning Charging Unit Contacts  
To maintain a good charge, it is important to clean all  
charging contacts on the handset, spare battery pack  
(DKT2204-CT only) and charging unit about once a  
month (shown right). Use a pencil eraser or a soft dry  
cloth. Do not use any liquids or solvents.  
DKT2204-CT Charging  
Unit (pictured)  
Charging Spare Battery Packs (DKT2204-CT only)  
The charging unit of your cordless telephone is equipped to charge the spare battery  
pack with or without the handset in the front slot.  
1. Slide the spare battery pack into the second slot in the  
charging unit until the retaining clip snaps over the top of  
the pack.  
2. Make sure the BATT CHARGE indicator lights. If the  
BATT CHARGE indicator doesn’t light, check to see that  
the AC adapter is plugged in, and that the battery pack is  
making good contact with the unit’s charging contacts.  
Note Charge the battery pack without interruption for 12~15  
hours.  
3. When charging is complete, press out on the latch and  
remove the battery pack for use. Or, if you don’t need the  
battery pack immediately, leave it in the charging compartment. It will not  
overcharge.

Troubleshooting and Specifications  
Simultaneous Conversation Channels  
Simultaneous Conversation Channels  
DKT2204-CT  
The DKT2204-CT cordless digital telephone has 10 operating channels available.  
A common misconception is that this limits a customer to 10 cordless telephones. This  
is not the case. Each cordless digital telephone can operate on any of the 10 channels.  
When you turn on a cordless digital telephone, the telephone selects an available  
channel within its’ range. In a given cordless range, 10 simultaneous calls can be  
made. In most businesses, it is unlikely that all 10 channels will be in use at the same  
time. Typically 20 to 30 telephones can share the 10 channels.  
Another factor is the distribution of the telephones in a facility. If your cordless digital  
telephones are disbursed throughout a facility, there should not be contention for  
channels. If there are more than 10 cordless digital telephones in one area and 10 users  
th  
are using their cordless telephones, an 11 user would not be able to connect at that  
time.  
DKT2304-CT  
The DKT2304-CT cordless handset has 30 operating channels available. A common  
misconception is that this limits a customer to 30 handsets. This is not the case. Each  
handset can operate on any of the 30 channels because each one selects an available  
channel within its range. In a given range, 30 simultaneous calls can be made.  
Another factor is the distribution of the telephones in a facility. If your handsets are  
disbursed throughout a facility, there should not be contention for all channels. If there  
st  
are more than 30 in one area and 30 users are using their handsets, the 31 user would  
not be able to get dial tone.

Troubleshooting and Specifications  
Range and Performance  
Range and Performance  
The DKT2204-CT operates up to 1.1 miles and the DKT2304-CT .7 miles from its  
base in a completely unrestricted test environment. Typically, ranges of 300 to 400  
feet are possible, depending on the building structure in which it is used. For optimum  
range and performance from your handset, try the following:  
Place the base units at least three to six feet away from the DKT; three feet from  
metal structures; and six feet from computers, fax machines or other electronic  
equipment.  
Use an AC outlet not associated with computer or electromagnetic equipment.  
Wherever possible, put the base unit in the middle of the coverage area.  
Mount the base unit high in the room for maximum range.  
If you have two to three cordless telephones, put them 12 feet apart.  
If you have four to 10 cordless telephones, put them 20 feet apart.  
If you want to use more than one cordless telephone in your office, they must  
operate on different channels. Press the Channel (DKT2204-CT)/CH (DKT2304-  
CT) button on the handset to select a channel that provides the clearest  
communication.  
Radio Interference  
Radio interference occasionally interrupts conversations, which does not mean that  
your unit is defective. Move to a different location while you are talking. If the  
interference continues, move the base unit. If there is still interference, contact your  
System Administrator.

Telephone Line Problems  
Telephone Line Problems  
The FCC and IC have granted the telephone company the right to disconnect service  
in the event that your telephone causes problems on the telephone line. Also, the  
telephone company may make changes in facilities and services which may affect the  
operation of your unit. However, your telephone company must give adequate notice  
in writing prior to such actions to allow you time for making necessary arrangements  
to continue uninterrupted service.  
If you are having trouble with your telephone service, you must first disconnect your  
telephone to determine if it is the cause of your problem. If you determine that it is the  
cause, you must leave it disconnected until the trouble has been corrected.  
Privacy  
Cordless telephones are radio devices. Communications between the handset and base  
unit of your cordless telephone are accomplished by means of radio waves which are  
broadcast over the open airways. Because of the inherent physical properties of radio  
waves, your communications can be received by radio receiving devices other than  
your own cordless telephone unit. Consequently, any communications using your  
cordless telephone may not be private.  
DKT Mode  
When a Toshiba Digital Telephone is connected to the Base of a cordless handset, the  
cordless telephone LCD will display “DKT Mode” whenever the digital telephone is  
in use.  
Important! If the cordless telephone is in a stand-alone configuration and its LCD  
displays “DKT Mode” the Off-hook Preference assignment in Program  
204-13 is probably not set correctly; the Off-hook Preference of all  
cordless telephones must be set to “Ringing” or “No Preference.”
