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.

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:  
Follow-me to voice mail  
Follow-me to the operator  
If an answering machine, a fax or other answering service is  
used as an early answering position, it might interrupt the  
searching.  
Disconnect the answering service, 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

extension. Answer the call in the normal way.  
Individual Night Service  
Selected external calls to the operator are transferred to one  
specific extension. Answer the call in the normal way.

Installation  
Connect the adapter to the charger and connect it to the  
mains outlet as shown in the figure below.  
Notes:  
Place the DT292 in the charger and charge it for at least 4  
hours before using it the first time.  
Make sure the local mains voltage corresponds to the  
voltage on the charger.  
Only use the charger that comes with the cordless phone.  
Do not connect the phone to the charger without a battery.  
Place the cordless phone in the charger to charge the battery.  
Complete charging before you subscribe or use the cordless

section “Battery” on page 89.

Installation  
Battery  
The cordless phone is powered by a rechargeable battery. You can  
fully charge an empty battery by placing the cordless phone in the  
charger for 4 hours. A fully charged battery gives you up to 17  
hours calling time or up to 140 hours standby time.  
Note: The calling time and standby time is shortened if the  
hands-free speaking function is used a lot.  
The cordless phone has a battery meter, which indicates the power  
remaining in the battery.  
Note: The cordless phone is powered by a Nickel Metal  
Hydride (NiMH) battery. It can be recharged at any time. To  
keep the battery fully charged, you can put or leave the  
cordless phone in the charger without any problem.  
Reading the battery meter  
When the battery is fully charged, the battery meter on the cordless  
phone display consists of four blocks. The number of blocks  
decreases as the battery discharges. If the battery is almost empty,  
the battery meter and the red light on the cordless phone flash. An  
alarm sounds if there is less than 15 minutes calling time remaining  
in the battery.

Installation  
Charging the battery  
Place the cordless phone in the charger as shown in the  
figure below.  
The battery is being charged when the lower green LED (Light  
Emitting Diode) on the charger is on (and the battery meter on the  
display flashes). If the battery is completely empty it can take a few  
minutes before the lower green LED on the charger is lit.  
When the battery is 90% charged, the LED starts flashing (3  
second intervals) and when the battery is fully charged, trickle  
charging starts (LED lights up for 1 second every 30 seconds) and  
the battery is ready.  
Notes:  
Place the DT292 in the charger and charge it for at least 4  
hours before using it the first time.  
Make sure the local mains voltage corresponds to the  
voltage on the charger.  
Only use the charger that is delivered with the cordless  
phone.  
Do not connect the phone to the charger without a battery.

Installation  
Changing the battery  
Rechargeable batteries have a limited lifespan. If the standby time  
for the cordless phone becomes too low, you should replace the  
battery. Please contact your system administrator or supplier for  
more information.  
Note: Only use the specified batteries (NiMH pack 600  
mAh, 3.6 V).  
The battery does not contain cadmium and is therefore more  
environmentally-friendly than other rechargeable batteries.  
However, all batteries should be treated as chemical waste.  
Clip  
The cordless phone has a clip to attach the phone to your clothes.  
To attach the clip to the cordless phone  
See section “Preparing for use” on page 87 for specific instructions.  
To remove the clip from the cordless phone  
Note: To minimize wear and tear, we recommend that you  
do not remove the clip from the cordless phone too often.  
Remove the clip from the back of the phone as shown in the  
figure below.
