Tips for opt imum recept ion
! Transmission range depends t o a large extent on location and on t he
selected output power. There should be a “free line of sight ” between
transmit ting and receiving antennas.
! To avoid overmodulating the receiver, observe a minimum distance of
5 m between transmit ting and receiving antennas.
Tips for multi-channel operat ion
! When operating a mult i-channel system, make sure t o only use
intermodulation-free frequencies.
