Important User Information  
Do not solder lead wires directly onto the battery.  
Power supply  
Do not allow water to come into contact with the  
battery.  
Connect the AC power adapter of the charging  
unit only to the designated power sources as  
marked on the charger.  
The initial charging of a NiMH battery will cause  
the battery to become warm. This is a normal  
effect of charging NiMH batteries.  
Make sure the cord is positioned so that it will not  
be subjected to damage or stress.  
The batteries are replaceable, however it is not the  
intention to do this frequently.  
To reduce risk of electrical shock, unplug the  
chargers from any power source before  
attempting to clean or move it.  
Only charge the batteries when placed in the  
phone.  
The AC power adapters must not be used  
outdoors or in damp areas.  
Use only the specified battery-packs for your  
product.  
Never modify the cord or plug. If the plug will not  
fit into the outlet, have a proper outlet installed by  
a qualified electrician.  
Never heat or dispose of the battery into a fire,  
which, or else, may cause leakage, burst or fire.  
Limit the distance between the mains socket and  
the cordless phone when charging for easy  
accessibility.  
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.  
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.  
The cordless phone can be charged either when  
switched on or off.  
Do not pull on cables.  
Do not connect the battery's positive and  
negative leads altogether in any circumstances.  
Do not strike or drop the battery. It may cause  
damage to the battery.  
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.  
Do not charge the battery below +5°C  
(+41°F). Be sure to charge the battery  
between +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.  
Only use batteries, mains adapters or desk and  
rack chargers which have been specifically  
designed for use with your product.  
The battery is to be stored in a dry cool place, with  
the ambient temperature of approx. +25°C  
(+77°F) for best performance.  
Use of power sources not explicitly  
recommended may lead to overheating, reduced  
battery performance, distortion of the equipment  
and fire or other damages.  
The battery continues to discharge a minimal  
portion of its power, even if the product is  
switched off or the battery is removed.  
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  
Dispose the battery in accordance with all local  
regulations, applicable in your country.  
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.

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.

Parallel Ringing  
Note: This function is only available in newer versions of the  
exchange.  
The Parallel Ringing function makes it possible for an incoming call  
to ring several phones simultaneously and for the call to be  
answered on any of the phones. The main advantage of this  
function is that you do not risk losing any calls.  
The function requires all the phones involved to be defined in a  
Parallel Ringing list, which must be configured and initiated by  
your system administrator. Because only calls to a main extension  
will be distributed among the phones in the list, this main extension  
also needs to be defined.  
A call to a specific extension will not be distributed to other phones  
in the list, and will only ring that specific extension's phone.  
Parallell Ringing can be temporarily disabled by the phone user  
using the function “Internal Follow-me”. See also section “Internal

Personal Number  
With this feature you can be reached on your normal office phone  
number even if you are out of the office, at home, etc.  
Depending on the functionality of your office exchange, you can  
have either one individual single search profile (standard) or you can  
choose between five individual search profiles (optional).  
A search profile can be designed to fit the situation, i.e. in the office,  
traveling, at home, etc. Both internal or external phone numbers  
can be used in a profile.  
Your search profile is programmed or modified by your system  
administrator. See section “To design and order your search  
profiles” on page 64.  
When the feature is activated, incoming calls are transferred to your  
selected phones or back-up services in the order that you choose.  
If an answering position in the profile is busy, the call can be  
transferred to another predefined position in the profile, i.e. Voice  
Mail or a colleague.  
You can handle the profiles from your own office phone. How to do  
this is described in this section (an operator can also assist you).  
You can also use any of the Personal Assistant applications, if  
available. Contact your system administrator for more information.  
When out of the office, the feature Direct Inward System Access  
(DISA) can be used, if available in your system. How to use DISA is  
described in this section.

To design and order your search profiles  
The search profiles are installed or changed by your system  
administrator. In order to set up your profiles, copy the setting form,  
fill in your new or changed profiles and give it to your system  
administrator.  
Note: If a profile handling application is connected to your  
system, you can edit profiles via your Intranet. See separate  
instructions for the application.

DT590  
Call Forwarding  
Important notes when designing your search profiles:  
Avoid ring times longer than 45 seconds for your profiles.  
Usually the caller hangs up after 3–6 ring signals. If you need a  
longer ring time, the maximum time is 60 sec.  
Consider the time you need to react and answer on each  
answering position in your profile.  
You might need up to 15 seconds to react and answer a call on  
a desk or cordless phone and 20–25 seconds for a mobile  
phone.  
There must be an answering position at the end of every profile  
(Voice Mail or operator/secretary).  
If not, calls might end up unanswered.  
Consider what should happen while you are busy on a phone.  
The available options are:  
Diversion to Voice Mail  
Diversion to the operator  
If an answering machine, a fax or other answering device is  
used as an early answering position, it might interrupt the  
searching.  
Disconnect the answering device, or design the ring times so  
they do not affect the searching.  
If your system admits just one single personal profile, design the  
profile only with your 2–3 most frequently used positions.  
If you add more numbers, there is a risk that the caller hangs up  
before a latter position is called.  
If your system admits 1–5 personal profiles, design the different  
profiles to fit your most frequently used positions.  
Make sure you use as few answering positions as possible for  
each profile. Profile examples:  
In office  
At home  
Traveling  
Absent/not reachable
