3. Connect the mains adapter to the charger and connect it to the mains out-
let.
If you place the charger on a wall, screw the wall mount to the wall.
4. Place the cordless phone in the charger to charge the battery.

Getting started 14
Complete charging before you subscribe or use the cordless phone. The
green light of the charger is turned off when charging is completed. For more
information about charging the battery, please refer to “Battery” on page 15.

Getting started 15
5. Subscribe the cordless phone to the telephone network. Follow the proce-
dure in “Subscribing to a network” on page 97.
When the cordless phone is subscribed to a telephone network, the cordless
phone is ready for use. See also “Telephone networking in short” on page 34.
The cordless phone is powered by a rechargeable battery. You can fully
charge a flat battery by placing the cordless phone in the charger for 3 hours.
A fully charged battery gives you up to 15 hours calling time or up to 150
hours stand-by time. The cordless phone has a battery meter, which indicates
the power left 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.
BATTERY

Getting started 16
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 bat-
tery discharges. If the battery is almost flat, the battery meter and the red light
on the cordless phone flash. An alarm sounds if there is less than 15 minutes
calling time left in the battery.
Charging the battery
Place the cordless phone in the charger as shown in the picture below.

Getting started 17
If the lower green light on the charger is on (and the battery meter on the dis-
play flashes), the battery in the cordless phone is being charged. As soon as
the battery is fully charged, the lower green light is turned off and the battery
meter on the cordless phone stops flashing.

Getting started 18
If the battery is completely flat it can take a few minutes before the lower
green light on the charger comes on.
Changing the battery
Rechargeable batteries have a limited lifespan.
If the stand-by time for the cordless phone becomes too low, you should
replace the battery. Please contact your system manager or supplier for more
information.
Warning
Only use batteries as specified in “Technical specifications” on page 127.
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.

Getting started 19
The cordless phone has a clip to attach the cordless phone to your clothes.
•How to attach the clip to the cordless phone: see “Preparing for use” on

•How to remove the clip from the cordless phone: see the drawing below.
Note
To minimize wear and tear, we recommend that you do not remove the clip
from the cordless phone too often.
