10. Getting started with the transmitter
In the operating instructions, the numbers in the text always relate to the illustration opposite
or the illustrations within the section.
Cross references to other illustrations are indicated with the respective illustration number.
a) Inserting the batteries/rechargeable batteries
For the power supply of the transmitter you will need 8 alkaline batteries (e.g. Conrad item no. 650117) or
mignon rechargeable batteries (AA). For ecological and also for economical reasons it is recommended to
use rechargeable batteries, since they can be recharged in the transmitter via a built-in charging socket.
To insert/replace the batteries or rechargeable batteries, please proceed as follows:
• The battery compartment lid (1) is located on the bottom
of the transmitter. Please press the serrated triangle (2)
and slide the lid off sideways.
• Now insert the 8 batteries or rechargeable batteries in
the battery compartment.
Pay attention to the correct polarity of the cells. The mi-
nus pole of the battery or rechargeable battery (3) must
have contact with the spiral spring (4).
• Afterwards slide the lid of the battery compartment back
on and let the locking mechanism click into place.
b) Loading the rechargeable batteries for the transmitter
• If rechargeable batteries are used to operate the model,
you can connect a charging cable to the charging socket
(5) and charge the rechargeable batteries in the trans-
mitter when the transmitter is switched off.
• It is very important that you pay attention to the correct
polarity of the connector plug. The inner contact of the
charging socket must be connected with the plus con-
nection (+) and the outside contact with the minus con-
nection (-) of the charger.
• The charging current should be approx. 1/10 of the ca-
pacity 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 is approx. 14 hours.
In order to avoid damages of internal circuit paths and connections, please don't use fast charg-
ers.
Since a protective diode is integrated in the transmitter, no chargers can be used that briefly
interrupt the charging current in order to measure the current rechargeable battery voltage. In
this case, the rechargeable batteries have to be taken out of the transmitter.
