6 RF Channel Change
In order to ensure an interference-free operation of a radio control system it may be necessary to change the
RF channel preset by the manufacturer. Changing the RF channel can become necessary due to
interference or in the event that a RF channel is already in use by another system. The RF channel can be
changed either by reprogramming the TransKey (external programming) or by using the RF channel
selection feature of the transmitter unit as described below.
NOTE
!
The features described in this section are available with standard transmitter units, furnished with
a key switch and horn push-button. Should these control elements not be available, these features
may not function either in part or entirely.
6.1 Working Principle
The operating RF channel of the transmitter can be changed, using the push buttons in the LED/Push button
panel. For this, the transmitter must first be brought into
Programming Mode . The respective RF channels
are displayed by the 4 LEDs located to the left and right of the STATUS LED. Each RF channel has been
assigned a specific colour code, shown in the 'RF Channel Tables'.
