The scanner module can be installed in any MULTIPLEX ROYAL evo transmitter which is fitted with an HFM-S Synthesizer RF module. It
enables the user to search the transmitter’s frequency band for channels which are already in use. The channels in use, and the field strength
of each transmitter, are displayed in a clear graphic (bar) form on the transmitter screen. When you switch the transmitter on the scanner also
checks automatically whether your selected transmission channel is free. The transmitter only activates the RF module (power-on guard) if that
channel is actually vacant. This is an extremely useful aid, and represents a major contribution to improved security in model sport. The scanner
module can be installed very easily at any time; it is simply plugged onto the HFM-S Synthesizer RF module.
