CHANNEL scanning
For an interference- free operation, a cleaner channel might be necessary if the current one
receives too much interference. To operate the scanning:
1 Press MENU button to make the frequency icon appear on the bottom.

2 Press ENTER button until this icon flashes to denote readiness for setting.

3 Press ▲(up) or ▼(down) button to find and locate a clear, interference- free channel.

4 After a channel is chosen, press ENTER button or wait 5 seconds to store the setting.

Channel synchronizing between receiver and transmitter
Align infrared areas of the receiver and transmitter within 10~30cm.
Changing the receiver’s channel
1 Press the synchronizing button of the
transmitter.
2 The transmitter's LED will glow to denote
synchronizing signal transmitted.
3 The channel/frequency of the receiver will
change and then the synchronization is
complete.
Changing the transmitter’s channel
1 Press the SYNC button of the receiver
2 The receiver’s LCD will show to
denote synchronizing signal being sent.
3 The channel/frequency of the transmitter will
change and then the synchronization is
complete.
If it doesn’t work check that you have the IR sensor panels aligned, that they are facing each
other, devices are within 10~30cm of each other, and try again.

SQUELCH (SQ) adjusting
When interference is encountered try reducing the sensitivity of the receiver, thus less
susceptible to interference. To operate the squelch setting:
1 Press MENU button to turn to the squelch setting page.

2 Press ENTER button until this icon flashes to denote readiness for setting.

3 Press ▲(up) or ▼(down) button to select a new squelch (sensitivity) level between 1
and 10.

4 After a squelch (sensitivity) level is chosen, press ENTER button or wait 5 seconds to
store the setting.

Audio output connection
There are three audio outputs on the back of the receiver, Mic-level balanced (channel 1 and
channel 2), and Line-level unbalanced (mixed). Use shielded audio cable for the connection
between the receiver and the amplifier/mixer. If the amplifier/mixer has a 1/4"(6.3mm) phone
jack, connect a cable from the 1/4"(6.3mm) unbalanced audio output from the receiver to the
amplifier/mixer. If the amplifier/mixer has an XLR input, connect a cable from the balanced XLR
audio output from the receiver to the amplifier/mixer input.
Mixed unbalanced audio output

Individual balanced audio output
Rack mounting
The receiver can be cabinet-mounted with accompanied kit as illustrated below.
