Recommendations and tips

... for the diversity receiver
• Make sure that the antenna and the earphones cable do not cross.
• For best results, make sure that the transmitter sensitivity is correctly
adjusted.
... for optimum reception
• Transmission range depends to a large extent on location and can vary
from about 10 m to about 150 m. There should be a “free line of sight”
between transmitting and receiving antennas.
• To avoid overloading the receiver, observe a minimum distance of 5 m
between transmitting and receiving antennas.
... for multi-channel operation
• When operating a multi-channel system, you should only use the chan-
nels within one frequency bank. Each of the frequency banks “ 1 ” to
“ 20 ” accommodates factory-preset frequencies which are intermodu-
lation-free.
• The frequency banks “ U1 ” to “ U6 ” allow you to freely select and store
receiving frequencies (see page 17).
• When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
