Important Information about the Battery
Use the battery only as directed. Never use a damaged or flat
battery.
Heat and cold reduce the performance and the lifetime of the
battery. A handset with either a hot or a cold battery can be
temporarily out of operation, even when the battery is fully
charged.
Dispose of used batteries in accordance with your local regula-
tions. Make use of available recycling facilities.
Never throw a battery into a fire.
Charging and Discharging
The battery can be charged and discharged hundreds of times.
When the operating time (i.e. call and standby time) has
become noticeably shorter than normal, the battery should be
replaced.
A fully charged but unused battery discharges itself in approx.
one week at room temperature.
In order to achieve long operating times, you should discharge
the battery at intervals by not placing the handset in the charg-
er, and leaving it switched on until it switches itself off. Only use
this method to discharge the battery.
Extreme fluctuations in temperature have an effect on the
charging capacity of the battery.
