Maintenance
Recharge batteries after use with the enclosed charger. To prevent a lazy
battery effect, discharge the devices every 5 times completely by using the
automatic switch off (Leave the system on, until it turns off automatically).
Afterwards, charge the devices as usual.
The devices have to be turned off before connecting to the charger. If this
is disregarded, the system might get damaged!
4.1 shows the pinning of the charge connector. Chargers have to be
connected to pin 2 (+) and pin 4 (GND). An external supply (6…8V, 0.5A)
can be connected to pin 3 (+) and pin 4 (GND).
Use only power supplies
which are certified by Frankonia.
Maximum charging
current is 1 A
