... for multi-channel operation
• For multi-channel operation, you should only use the channels within
one frequency bank. Each of the frequency banks "1" to "20" accom-
modates factory-preset frequencies which are intermodulation-free.
• When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
