c) Charging Rechargeable Batteries in the Transmitter
The transmitter is equipped with a charge socket (see figure 3, pos. 4) to charge the inserted recharge-
able batteries.
Please note the following safety instructions and information:
If batteries are inserted in the transmitter a charger must not be connected. Conventional
batteries (1.5V/cell) must not be recharged. There is a risk of fire and explosion!
Only charge rechargeable batteries (1.2V/cell) intended for this purpose.
The transmitter has to be switched off during the charging process.
Please also observe the correct polarity of the connector plug. The inner contact of the
charge socket has to be connected to the plus connection (+) and the outside contact to
the minus connection (-) of the charger.
The charging current should be approx. 1/10 of the capacity value of the inserted
rechargeable batteries. For rechargeable batteries with a capacity of 2000 mAh this
corresponds to a charging current of approx. 200 mA and the charging time takes approx.
14 hours.
In order to avoid damages of internal circuit paths and connections, please don't use fast
chargers.
Since a protective diode is integrated in the transmitter, do not use chargers that briefly
interrupt the charging current in order to measure the current rechargeable battery voltage.
In this case, the rechargeable batteries must be removed from the transmitter.
With NiCd rechargeable batteries a memory effect can occur. If NiCd rechargeable batteries
are charged when they are not fully discharged, their capacity diminishes in the course of
time. Thus, such rechargeable batteries must be discharged with an appropriate charger
outside of the transmitter and then charged completely again.
