4.3 Battery Charging
To recharge the built-in 7.2 Ah accumulator we recommend our
automatic battery charger DL-50A.
Charging should be done within the ambient temperature range of
+10°C to +40°C.
The charger DL-50A is designed for
connecting to 115 Vac or 230 Vac, 50 to
60 Hz mains. For operation, check that
the unit's operating voltage is identical
with your local mains supply. If required,
set the voltage selector switch by means
of a suitable tool to the respective voltage,
changing of the fuses is not required
(DL-50A is factory pre-set to 230 Vac).
For charging the internal battery
connect charger cable of DL-50A to
the 3-pole DIN socket 14 of carrying
case PS.
Plug the mains cable into a suitable
wall outlet. The red pilot lamp
(POWER) lights up.

Charging lasts up to 30 hours depending on the state of the battery
(for 7.2 Ah battery). When the switch-off voltage is reached the
charger switches automatically to trickle charge. The capacity at the
end of charging is about 90% of the full rated capacity.

The built-in lead acid battery is now continuously charged on low
current. The full capacity of the battery is thus guaranteed.
Overcharging the battery is not possible due to automatic controlled
charging function, even if the trickle charge is maintained over a long
period.
The transceiver may be operated while charging.
For trickle charging or buffer operation the charger can be left
unattended continuously connected to mains.
A fully charged battery can be stored for several months.
