Charging and
Discharging
A battery may be charged and discharged hundreds of times,
but eventually it will be used up. When you notice that operat-
ing time (i.e. talking and standby time) is much shorter than
normal, it is time to replace a battery.
If, for any reason whatsoever, you do not use the charger for a
longish period, withdraw the AC adapter from the mains out-
let. Overcharging can reduce the useful life of a battery, so do
not leave a battery in the charger for more than one week. A
fully charged but unused battery discharges in about one
week at room temperature.
To produce long operating times, you should discharge the
battery from time to time, i.e. do not place the handset in the
charger and leave it switched on until it switches itself off. Do
not discharge the battery in any other way.
Extreme temperatures affect the ability of a battery to charge.
Charging the Battery
First-time
Startup
Charge the battery for at least eight hours before using the
handset for the first time. This helps to lengthen the battery’s
useful life. Place the handset in the charger regularly to obtain
the optimum battery charge.
Charging a
Spare Battery
To charge a spare battery, open the flap on the inside of the
charger (1). Insert the spare battery in the compartment (2)
and then close it again with the flap (3).
