Installation
Charge Display
The charge status of the batteries is indicated on the display:
ƒ
batteries are 81 - 100% charged
batteries are 61 - 80% charged
batteries are 41 - 60% charged
batteries are 21 - 40% charged
batteries are 0 - 20% charged
(frame flashes) batteries are almost empty; a warning has been given.
Your handset has a battery management system which has to ascertain the limits of the battery
charge status first before it can output the correct status to the display.
When you insert the batteries for the first time, the charge status will not be displayed correctly
until they have been completely discharged and then completely recharged.
When the handset is placed in the charger cradle, the flashing or lit segments indicate the charging
process or charge status respectively.
Charge Warning
When the batteries' capacity is almost exhausted, the battery icon in the display will flash, and an
acoustic warning is given in the form of three short “beep” signals every minute. If you are making a
call, you have approximately five minutes' talk time left before the handset switches itself off.
Use only rechargeable NiMH batteries. Never use normal, nonrechargeable batteries or fuel cells (see
page 58).
Note
You can replace your handset in the charger cradle after every call if you wish. The charging process
is electronically regulated so that the batteries are always optimally recharged, whatever their
charge level at the time. Do not remove the batteries from the handset unless there is a good reason
for doing so. Removing the batteries interrupts the optimized recharging process.
The capacity of the batteries can be increased by discharging them
completely in the handset when
they have been in use for a long period and then
fully recharging them again.
