Charging and using the Ex battery pack
To charge the Ex battery pack, place the handset in
the charging unit with the keypad facing forwards.
The battery is supplied partially charged. Charge
●
the battery before using it for the first time until
the charging light extinguishes (<3h). Full battery
capacity is only reached following a number of
charging cycles.
Depending on the technology, the battery capacity
diminishes after several charging cycles.
When the battery is fully discharged (battery low
warning tone), the charge status indicator adapts
to the actual battery capacity.
For future charging – you can replace your hand-
●
set in the charging unit each time it has been
used. Charging is electronically controlled which
ensures that the Ex battery pack is charged opti-
mally.
The Ex battery pack should be replaced by approp-
●
riately trained service personnel:
– Due to ageing: the capacity of the Ex battery
pack can diminish to the extent that it is no lon-
ger sufficient (increasingly faster discharge) for
the intended operating life.
– If there is a noticeable change in the battery
(appears thickened, damaged by a fall, etc.)
– If used in other devices or unsuitable chargers.
The charging status is indicated by the charge status
indicator. This flashes while charging:
