Turn volume controls of the r eceiver and mixer in use to a minimum
setting before t urn on the microphones or transmitters. After
switches on the receiver, the power switch red indicator illuminates
todenotenormal power status.
(a) Unbalanced Audio Output: Switch the level switch(7) onthe receiver
rear panel tothe leftposition "MIC" , thenadjustvolumecontrol of the
amplifier or mixer toobtainan appropriatesoundlevel of the
microphone.
(b) To obtain same sensitivity andvolumelevelof both wired and wireless
microphonesin a mixer o r amplifier that has morethan 2 microphone
inputsockets, one can adjust the wired microphone volume control in
the mixeroramplifier. After reaching desired sound level, connect to
the AFoutput socketofreceiver. Please note that the unbalanced
volume switch on the backof th e receivershouldswitchto "MIC"
position.
(c) If thereceiver outputlevel is adjusted excessively, it willcause the
saturation d i stortionof the mixer oramplifier when the microphone is
loud.

Make sure that the system performs correctly by placing thesystem
away from noise sources. Place the r eceiver at least 1 meter above
the ground and away f rom noise sources. Place the microphone at
least 1 meter away from the r eceiving antenna, as s hown in Fig. 6.

IfSIGNALLEDindicators(3)of the receiver light on before
switches on the microphone ortransmitter, itindicates the receiver is
receiving interference signals. This s ystem has Pitlotone and
NoiseLock dual-squelchfeatures and no noise output will occur. I f
multiple channels are used andboth SIGNALand AUDIO LEDs
glow andinterference noise a ppear, simply a djust theSquelch
controls (8) clockwise until A UDIO signal indicators to extinguish.
(Fig. 8). However, by adjusting the s quelch controls, it affects the
sensitivity levelof the receiver, therefore, shorten the operating
distance and decreases the stability.

Under normal circumstances, the SIGNAL indicator lights up when a
microphone or transmitter is turned onnear the receiver to indicate
the receiver is ready fornormaloperation. Once sounds to the
microphone and the AUDIO LED indicators (4) will glow according
to the strength of sound level. If no LED glows or no sound outputs,
the system is notfunction properly, thus it must be checked.
