b) Switching on the transmitter
When the new batteries have been inserted, switch on
the transmitter for testing purposes using the on/off switch
(see also Figure 2, Pos. 10). To do this, move the control
knob from the left (OFF) to the right (ON).
The red LED for the operation control (see also Figure 2,
Pos. 13) lights up and shows you the switched-on status
of the transmitter.
The green LED for the low voltage indicator (see also
Figure 2, Pos. 8) lights up permanently and signals the
adequate power supply of the transmitter.
If the power supply drops below 4.3 V, the green low volt-
age indicator will start flashing.
In this case, you should stop operating your model as
quickly as possible. To continue operation of the transmit-
ter, new batteries must be inserted.
After checking the correct function of the transmitter, switch it off again.
