Guidelines, warnings and precautions for  
safe and efficient use  
Recommendations  
Always keep and handle your products with care and keep  
them in a clean and dust-free place. Proper use and care will  
prolong the products life. Use a soft absorbent tissue or cloth to  
remove dust, dirt or moisture.  
Always ensure that the phone, battery and charger are used and  
operated in the intended environment for which they are  
designed.  
Operate the phone in temperatures between 0°C to +40°C  
(32°F to 104°F).  
Do not expose your products to liquid, moisture, humidity,  
solvents, strong sunlight, harsh environments or extreme  
temperatures, never above +60°C (+140°F).

BusinessPhone – Cordless DT590  
     
Important  
Exposure to heat may cause batteries to leak, overheat or  
explode, resulting in fire, burns or other injuries.  
Do not put the product in the microwave oven: This may cause  
damage to either the oven or the product.  
Do not attempt to disassemble or alter any part of the phone,  
the charger(s) or the battery-pack. Disassembly or alteration  
may result in electrical shock or irreversible damage to the  
equipment. Only a qualified service personnel or an authorized  
Ericsson partner should conduct internal inspections,  
alterations and repairs.  
Do not expose your product to open flames or lit tobacco  
products.  
Do not drop, throw or bend your products. This may cause  
malfunction or electric shock.  
Do not paint your product.  
Do not use your product in an area where a potentially explosive  
atmosphere exists.  
To avoid hearing impairment, accept the call before holding your  
product (or portable handsfree device) to your ear.  
The DT590 phone is not specified as intrinsically safe, so do not  
use it in areas with a danger of explosion.  
Disposing of the product  
Your product should not be placed in municipal waste. Please  
check local regulations for disposal of electronic products.  
Power supply  
Connect the AC power adapter of the charging unit only to the  
designated power sources as marked on the charger.  
Make sure the cord is positioned so that it will not be subjected  
to damage or stress.  
To reduce risk of electrical shock, unplug the chargers from any  
power source before attempting to clean or move it.  
The AC power adapters must not be used outdoors or in damp  
areas.  
Never alter the cord or plug. If the plug will not fit into the outlet,  
have a proper outlet installed by a qualified electrician.  
Limit the distance between the mains socket and the cordless  
phone when charging for easy accessibility.  
BusinessPhone – Cordless DT590  
7
Important  
As an energy saving measure, disconnect the charger from the  
main socket after charging.  
When unplugging the mains adapter from the power outlet,  
make sure that your hands are dry and ensure that you hold the  
solid portion of the mains adapter.  
Do not pull on cables.  
Charging and batteries  
Please read carefully the following important precautions  
before the first time use of the batteries. Make sure to  
understand and observe all cautionary instructions stated, so  
as to avoid any possible safety hazards that are caused by  
any misuse, misapplication or damage to batteries.  
Only use batteries, mains adapters or desk and rack chargers  
designed for use with your product.  
Use of power sources not explicitly recommended may lead to  
overheating, reduced battery performance, distortion of the  
equipment and fire or other damages.  
Cordless phones are equipped with Nickel Metal Hydride  
(NiMH) batteries or Lithium Ion Lion batteries. In a complex  
infrastructure, the talk- and standby time may differ, due to the  
consequence of the increase in signaling.  
The battery must always be completely charged (minimal 4  
hours) before first time use.  
The battery in your product is designed to withstand many  
charge cycles.  
Use only the recommended charging equipment.  
Improper charging can cause heat damage or even high  
pressure rupture.  
Observe proper charging polarity.  
Do not solder lead wires directly onto the battery.  
Do not apply water to the battery.  
The initial charging of a NiMH battery will cause the battery to  
become warm. This is a normal effect of charging NiMH  
batteries.  
The batteries are replaceable, however it is not the intention to  
do this frequently.  
Only charge the batteries when placed in the phone.  
Use only the specified battery-packs for your product.

BusinessPhone – Cordless DT590  
Important  
Never heat or dispose of the battery into a fire, which, or else,  
may cause leakage, burst or fire.  
Remove the carrying case from the product while in charger.  
Do not cover the product while being charged. Do not charge  
the phone in a closed cabinet or drawer. The charging of the  
battery is a chemical process and causes the battery to become  
warm during charging. Make sure the environment in which the  
phone is charged, is well vented.  
The cordless phone can be charged either when switched on or  
off.  
Do not connect the battery's positive and negative leads  
altogether in any case.  
Do not strike or drop the battery. It may cause damage to the  
battery.  
Do not charge the battery under the temperature of +5°C  
(+41°F). Be sure to charge the battery between the  
temperatures of +5°C and +45°C (+41°F and 113°F). Charging  
beyond these conditions may impair the battery performance  
and shorten the life cycle.  
Do not use battery packs from different types, brands or of  
different capacities.  
The battery is to be stored in a dry cool place, with the ambient  
temperature around of +25°C (+77°F) for best performance.  
The battery continues to discharge a minimal portion of its  
power, even if the product is switched off or the battery is  
removed.  
Dispose the battery in accordance with all local regulations,  
applicable in your country.  
Warnings  
Smoke or fumes  
Stop operating the products and turn off immediately in case of  
smoke or fumes. Unplug the mains adapter and remove the  
batteries from the phone immediately. Continued operation may  
result in fire or electrical shock.  
LCD  
If the liquid crystal display breaks, avoid injury by not letting the  
liquid crystal touch the skin, getting it into the eye or into the  
mouth or getting cut by the broken glass.

Important  
Preventing malfunction  
Never place the equipment in close proximity of electric motors,  
welding equipment or other devices generating strong (electro)  
magnetic fields. Exposure to strong (electro) magnetic fields  
may cause malfunction and corrupt the communication.  
Moving the equipment rapidly between warm and cold  
temperatures may cause condensation (water droplets) to form  
on its internal and external surfaces. Water droplets may cause  
malfunction of the equipment and corrupt or end  
communication or damage the equipment. When condensation  
is noticed, stop using the equipment. Switch off the phone,  
remove the battery and unplug the mains adapter from the  
power outlet. Wait until the moisture evaporates from the  
equipment before putting it in operation again.  
Avoid accidental drop of the phone. Use the clip, security clip or  
carrying case specified for carrying purposes of the phone.  
Avoid the phone being squeezed between furniture and your  
body when carrying the phone in your pocket or attached to  
clothing.

Fixed Diversion, Diversion when there is no answer, Diversion when  
your extension is busy and Diversion when charging) or an  
individual one.  
If you urgently need to talk to someone who has forwarded his  
calls, the system is also equipped with a bypass function.  
Depending on the type of diversion, you are also able to record  
your Personal Greeting for your mailbox, see section “Change your  
Personal Greeting” on page 66.

Group Features  
When you are working together in a team, the following group  
features can be very useful.  
Group Hunting  
Your phone can be included in one or several hunt groups. In a  
hunt group, all members are represented with one common  
directory number. 16 hunt groups can be programmed, each  
containing 1 to 20 members. A member can be either an extension  
number, an operator console or a fictive number. Please ask your  
system administrator if you require this function.  
Note: The number of cordless extensions in a hunt group is  
limited to eight (including tandem configurations).  
Incoming calls to the hunt group are directed to free extensions in  
the group. The hunt order within the group can be changed to suit  
your needs. If all members of the hunt group are busy, an incoming  
call is being queued. If no one answers this call before the  
programmed time, the call is forwarded to the programmed  
diversion address (e.g. operator).  
Note: If all members in a hunt group are busy, the Callback

Networking  
Networking is the connection of several premises within a  
company. The connection can be set up via leased lines, public  
lines, Local Area Network (LAN) or Wide Area Network (WAN). Ask  
your system administrator about details regarding networking.  
IP Calls  
IP calls are internal calls sent via an internal data network (LAN or  
WAN) and the transfer of data and voice is made on the same line.  
If you are connected to an internal data network, the IP connection  
is made automatically. To minimize the traffic on the network, the  
speech quality is decreased.  
If the speech quality is not acceptable, you can disconnect the  
IP call and switch to a non-IP call (Alternative network). The switch  
from the IP net to the non-IP net is made during the call, so the call  
does not have to be disconnected.  
If you want to switch to a non-IP net during the call:  
»
Press.  
*61*  
Press.  
During the procedure the other party is put on hold. When the  
procedure is ready, you will receive a special ringing tone and the  
call is resumed in the non-IP net.  
Note: A switch to a non-IP call can only be performed if the  
original call is an IP call, otherwise you will receive a blocking  
tone.

Useful Hints  
Useful Hints  
Connections between external lines  
With your BusinessPhone Communication Platform, you can  
establish an external call diversion or a conference with more than  
one external party or transfer an external call to another external  
destination (e.g. a mobile phone). These features are very useful for  
everyday business life.  
Note: When these features are used, your BusinessPhone  
Communication Platform will occupy at least two external  
lines.  
However, there may be disadvantages in connecting to several  
external lines. We would therefore like to draw your attention to the  
following:  
Please do not transfer external calls to an external  
mailbox, to information systems or to external parties  
before they have answered.  
If you are connected to two external lines, cancel one call  
by pressing “R” and “1”.  
If the external parties are not persons (mailbox, automated  
information or attendant systems, etc.), connections on external  
lines can last a long time, which can be costly. Moreover, such calls  
may occupy two of your systems external lines. You can restrict  
connections between the external lines by reprogramming your  
system.  
Please ask your system administrator or contact our service center  
for more information.

Installation  
Battery  
The battery compartment with the Li-Ion battery is placed on the  
rear side of the handset.  
Charging the battery  
The battery requires charging when the Battery icon in the display  
indicates low level.  
Place the phone in the charger. The charging status is shown by  
the Battery icon in the display. An empty battery is fully charged  
after approximately 4 hours, indicated by a filled Battery icon.  
Replacing the battery  
If the standby time for the cordless phone becomes too low, the  
battery should be replaced by a new one. Please contact your  
system administrator or your certified Ericsson Sales partner for  
more information.  
After replacing the battery with a new one, the Battery icon can  
indicate an empty battery even though it is fully charged. Placing  
the phone in the charger for a while will remove the problem.  
Note: To avoid fatigue of the phone’s battery connector,  
use the charger instead of repeatedly replacing an empty  
battery with a new one.
