2.4 Recharging the Battery using DL-5A/5W
(1)
(3)
(2)
The drop-in charger DL-5A/5W is designed for connecting
to 115 VAC or 230 VAC, 50 to 60 Hz mains. First of all ,
check that the unit's operating voltage is identical with your
local mains supply. If required, set the voltage selector
switch
(3) by means of a suitable tool to the respective
voltage, changing of fuses is not required. DL-5A/5W is
factory set to 230 VAC!
Plug the mains cable into a suitable wall outlet. The red
pilot lamp (
1) lights up.
For charging, insert the complete hand-held transceiver
FSG 5W or just the removed Ni-MH battery pack upright
into the charging chamber. A certain position of the battery
pack is not required.
If the battery is discharged, the charger switches
immediately to rapid charge (yellow lamp (
2) lights up).
Rapid charge - yellow pilot lamp (2) lights
The duration of charge depends on the state of the battery and is approx. 10 hours
at 250 mA (for a 1.5 Ah battery).When the switch-off voltage is reached the charger
switches automatically to trickle charge. The capacity at the end of rapid charging is
about 90% of the full rated capacity.
Trickle charge - yellow pilot lamp (2) goes off
The Ni-MH battery pack 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 and temperature controlled charging function, even if the trickle
charge is maintained over a long period.
Batteries in chargers operating on trickle charge are fully charged.
IMPORTANT!
•
To prevent fire or shock hazard, do not expose the unit to rain or
moisture.
•
To avoid electrical shock, do not open the cabinet. Refer repairing to
qualified personnel only.
•
The chargers must not be operated on or near heaters or in direct
sunlight.
•
Charging should be done within the ambient temperature range of
10°C to +40°C, otherwise the battery may not be fully charged.
•
The VHF Transceiver FSG 5W with attached battery pack may be
operated while being inserted into the drop-in charger, e.g. for
temporary fixed base use.
•
If a fully charged battery is removed briefly from the charger and then
reinserted the charging cycle starts again from the beginning: brief
rapid charging (yellow LED lights) followed by trickle charge. The Ni-
MH battery incurs no damage.
•
If the battery is flat it is first recharged on trickle charge until its terminal
voltage reaches a certain limit where rapid charging switches on
automatically.
