Important Information
discharging and charging of the battery pack avoids early capacity
losses of the cells.
7 Do not constantly change half-charged or even almost fully charged
battery packs. When operational reasons request changing the battery
pack, you should extend the change intervals so that the battery pack is
discharged to the greatest possible extent before it is replaced, but

without endangering safe unit function due to a discharged battery
(provide a operational standby period!).
8 If the service times of the unit are considerably shorter after extended
use of the unit, try the battery pack cure:
Discharging: Use the unit (handset) until the "battery-low" indication
appears.
Charging: Charge the battery pack as described in the Operating Manual.
Repeat this cycle (discharging, charging) several times.
With each pass, the battery pack regains a part of its initial capacity.
9 Harmful influences regarding the battery pack service life and beeing
outside of the manufaturer's control include:
Extremely low and high temperatures during storage and operation,
Permanent charging in the charger,
Deep discharge in the unit or while storing.
Handling battery chargers
• All two-pole-and-earth socket outlets for the plug-in power supply units
must be located near the chargers to be connected and must be
accessible at all times. The two-pole-and-earth socket outlets must have
been properly installed by qualified personnel.
Before plugging the power supply unit into the socket outlet: Make sure
that the available mains voltage matches the voltage indicated on the
plug-in power supply unit (e.g. 230 V, 50 Hz).
• Chargers and plug-in power supply units do not contain any user-
serviceable parts. Repairs must be carried out properly by qualified
personnel. Have defective or damaged chargers / power supply units
replaced by genuine spare parts only, even if only the cord is damaged.
• Warning – Handling of damaged power supply units!
Disconnect the socket outlet from the supply (remove or disable fuse of
