Battery information
This device has an internal, 
nonremovable, rechargeable battery. Do 
not attempt to remove the battery from 
the device as you may damage the 
device. This device is intended for use 
when supplied with power from the 
following chargers: AC-3, AC-4, AC-5, 
AC-8, AC-15, DC-4, DC-9, and DC-13. 
The exact charger model number may 
vary depending on the type of plug. The 
plug variant is identified by one of the 
following: E, X, AR, U, A, C, K, or B. The 
battery can be charged and discharged 
hundreds of times, but it will eventually 
wear out.
Talk and standby times are estimates 
only. Actual times are affected by, for 
example, device settings, features being 
used, battery condition, and temperature.
If the battery has not been used for a 
long time, to begin charging, you may 
need to connect the charger, then 
disconnect and reconnect it.
If the battery is completely discharged, it 
may take several minutes before the 
charging indicator is displayed.
When your charger is not in use, unplug 
it from the electrical plug and the device. 
Do not leave a fully charged battery 
connected to a charger, as overcharging 
may shorten the battery's lifetime. If left 
unused, a fully charged battery will lose 
its charge over time.
Always keep the battery between 15°C 
and 25°C (59°F and 77°F). Extreme 
temperatures reduce the capacity and 
lifetime of the battery. A device with a 
hot or cold battery may not work 
temporarily.
Do not dispose of batteries in a fire as 
they may explode. Dispose of batteries 
according to local regulations. Recycle 
when possible. Do not dispose as 
household waste.
