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.
