True Diversity
The Volume Control of the receiver is set too high, it may over-drive the input of the
mixer, causing distortion. Conversely, if the receiver output is set too low, the overall
signal to noise ratio of the system may be reduced. Adjust the output level of the receiver
such that highest sound pressure level going into the microphone causes no input
overload in the mixer, and yet permits the mixer level controls to operate in their normal
range (not too high or too low ).
This provides the optimum signal to noise for the entire system.

RF Interference
If you encounter receiving interference (from other than an operating TV station), often it
can be overcome by adjusting the receiver's squelch control, as described on below.
Please note that wireless frequencies are shared with other radio services. According to
FCC requlations, wireless microphone operations are unprotected from interference
from other licensed operations in the band. If any interference is received by any
Government or non-Government operation, the wireless microphone must cease
operation. The abovestatement is valid in the U.S.A.
Receiver Squelch setting
The squelch control setting is per LCD display on the front panel of the receiver is preset
at the factory, but can be adjusted if you must use the system in a high RF interference
area. If there is audio output from the receiver when your transmitter is OFF, adjust the
squelch control so the system will receive the signal from your transmitter but squelch
or eliminate the unwanted background RF noise. This adjustment can cause a reduction
in usable range of the wireless transmitter, so set the control to the lowest position which
reliably mutes the unwanted RF signal.
RACK MOUNTING
1. If external antenna is used, low loss RF shielded cable should be used and the length
of the cable
should not exceed 3m.
2. Do not place the receive antenna within 1 m of another receiver or antenna.
3. The receiver antenna should be kept away from any metal surface.
