Scanning & Changing CH NNEL
For an interference- free operation, a cleaner channel might e necessary if the current one
receives too much interference. Before scanning, the transmitter must e switched off.
Press ▲or▼ and the receiver will scan and stop at the next clean channel.
CH NNEL SYNCHRONIZING of the receiver and transmitter
1. To achieve successful synchronization hold the receiver and transmitter within 30cm of each
other.
2. Align oth IR sensor panels
3. To change the transmitter’s channel, press the sync utton on the receiver. The receiver will
transmit the frequency to the transmitter and synchronize the channels.
If it doesn’t work check that you have the IR sensor panels aligned, that they are facing each
other, devices are within 30cm of each other, and try again.
djusting VOLUME level
Volume level can e adjusted y rotating the Power/volume kno . Clockwise to increase the
volume and counterclockwise to decrease the volume.
djusting SQUELCH level
When interference is encountered try reducing the sensitivity of the receiver y turning the SQ
control clockwise, thus less suscepti le to interference. If this still does not solve the pro lem
it means this frequency is not suita le. Adjust the squelch ack to where it was and use the
scan function to locate a clear channel.
Receiver installation
For est operation, the receiver should e at least 1m a ove the
ground and 1m away from a wall or metal surface to minimize
reflections. The transmitter should also e at least 1m away from
a wall or metal surface to minimize reflections. The transmitter
should also e at least 1m away from the receiver. Keep
antennas away from noise source such as motors, automo iles,
neon light as well as large metal o jects.
udio output connection
There are two audio outputs on the ack of the receiver, Mic-level alanced and Line-level
un alanced. Use shielded audio ca le for the connection etween the receiver and the
amplifier/mixer. If the amplifier/mixer has a 1/4"(6.3mm) phone jack, connect a ca le from the
1/4"(6.3mm) un alanced audio output from the receiver to the amplifier/mixer. If the
amplifier/mixer has an XLR input, connect a ca le from the alanced XLR audio output from
the receiver to the amplifier/mixer input.

Rack mounting
The receiver can e ca inet-mounted y either one or two units. If only one receiver is to e
mounted, an optional kit is availa le and it's installed as shown in Fig 1. If two receivers are to
e mounted, they can e assem led y another kit and installed as shown in Fig 2.
