Care information for lithium ion batteries

This section contains information on how to obtain optimum service life from
your battery.
Use only the system-compatible chargers for charging the batteries!
Half-charged batteries can be stored separately from the units for an exten-
ded period (up to several months) at a storage temperature of 0 °C to
15 °C.
Batteries mounted on the unit become discharged during an extended sto-
rage period due to the idling current consumption of the phone and the bat-
tery. Charge the batteries in the unit once before the storage period and
then at regular 3-month intervals.
Charge flat batteries immediately by placing the unit into its charger.
Discharged batteries can be identified by the 'Battery flat' message or by
the failing unit function.
If the service times of the unit are considerably shorter after extended unit
use, you should replace the battery by a new one.
An important adverse effect on battery service life for which we cannot be
held responsible is any heavy heating of the battery during storage or ope-
ration. For this reason – whenever possible – do not leave the handset or
the batteries in the blazing sun or near heat sources for an extended pe-
riod.

Handling of chargers

All socket-outlets supplying the plug-in power supply units of chargers must
be located near the chargers and be accessible at any time. The socket-
outlets must have been properly installed by qualified personnel.
Before connecting the plug-in power supply unit with the socket-outlet:
Ensure that the available mains voltage is the same as specified on the
power supply unit (e.g. 230 V, 50 Hz).
Chargers and their plug-in power supply units do not contain any service-
able parts.
Repairs must be made properly by trained personnel. Have defective or da-
