CAUTION! Risk of reception interference!

If – within the receiver’s frequency range – transmitters transmit on channels from different frequency banks, reception can be subject to interference and inter-modulation. Only the factory-preset frequencies within the frequency banks “1” to “6” are interference and inter-modulation free.

Set all transmitters of a multi-channel system to different channels within the same frequency bank.

The varying accumulation of frequencies within the frequency banks allows you to use as many channels as possible in a crowded frequency band.
