10. Setting up the Transmitter
a) Inserting the Batteries/Rechargeable Batteries
The power supply to the transmitter requires 8 alkaline batteries (e.g. Conrad item no.: 652507, pack of 4, order 2) or
rechargeable batteries. For both ecological and economic reasons it is recommended that you use rechargeable
batteries.
Batteries can be charged while in the transmitter using the charging socket (figure 1, pos 9) For this
purpose, see chapter 10. b).
To insert the batteries or rechargeable batteries, please proceed as follows:
• The battery compartment (figure 1, item 7) is on the underside of the transmitter. Slide out the battery compartment
cover and remove it.
• Now insert the eight batteries or rechargeable batteries in the battery compartment. Be sure to observe the correct
polarity of the individual cells (note plus/+ and minus/-). You will find plus and minus labelling in the battery compartment.
• Replace the lid of the battery compartment again and close it.
b) Charging the Rechargeable Transmitter Batteries
Proceed as follows for recharging the rechargeable battery in the transmitter:
• Switch off the transmitter.
• Connect a suitable charging cable to the charging socket (figure 1, item 9). Always make sure the polarity of the
connecting plug is correct; see the illustration next to the charging socket. The inner contact of the charging socket
must be connected to the positive terminal (+) and the outer contact to the negative terminal (-) of the charger.
• The charging current should correspond to approximately 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 charging time takes approx. 14 h.
Do not use any quick chargers, since they will damage the conductor strips on the transmitter PCB. Note
the maximum charging current printed next to the charging socket.
If no charging current is indicated there, we recommend using a charging current of max. 250 mA.
Attention!
Connect the charger only if the rechargeable batteries (1.2V/cell) have been inserted in the transmitter.
Never try to recharge normal batteries (1.5V/cell) with a charger. There is a risk of fire and explosion!
