** Remark: The above specifications are subject to change without prior notice.
Important
1. Please make sure that the output DC voltage range of the switching power covers that
specified by the receiver before turning it on.
2. The RF indicator will glow to denote RF signal received after turning on the transmitter.
3. The receiver and transmitter must be the same frequency.
4. While using the transmitter, the audio signal indicator will glow to denote audio signal
received.

Adjusting VOLUME level
Both channel’s volume level can be adjusted separately by rotating its designated
volume knob.
Scanning & Changing CHANNEL
First turn on main power switch, the 7-segment display LED will show current channel number.
For an interference- free operation, a cleaner channel might be necessary if the current one
receives too much interference. Before scanning, the transmitter must be switched off.
Press ▲ and the receiver will scan and stop at the next clean channel.
CHANNEL SYNCHRONIZING of the receiver and transmitter
Align infrared areas of the receiver and transmitter within 10~30cm.

Instructions
Changing the transmitter’s channel
Press the sync button on the receiver. The receiver will transmit the frequency to the transmitter
and synchronize the channel.
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.
Adjusting SQUELCH level
When interference is encountered try reducing the sensitivity of the receiver by turning the SQ
control clockwise, thus less susceptible to interference. If this still does not solve the problem it
means this frequency is not suitable. Adjust the squelch back to where it was and use the scan
function to locate a clear channel.

Audio output connection
Unbalanced output: ¼” PHONE PLUG connector provides unbalanced audio output signal
from this jack to the mixer/amplifier.
Use an audio output cable with ¼” PHONE PLUG
connectors. Connect one end from the unbalanced output jack of the receiver, and the other
end to the “LINE IN” or “MIC IN” jack of the mixer/ amplifier.
Level switch setting: When connecting to the LINE /AUX IN of a mixer/amplifier, switch to
“LINE” position. DO NOT use the “MIC” position as they may not deliver a sufficient high
output level. When connecting to the “MIC IN” jack of a mixer/amplifier, switch to “MIC”
position. Overload distortion may occur at the wrong level position.

Mixed audio output
OUTPUT B can deliver mixed audio signal of both channels. After connecting to the amplifier
/mixer, slide the OUTPUT MODE to MIXED position and then CHANNEL A’s audio signal will
be delivered through OUTPUT B.
Receiver placement
For best operation, the receiver should be at least 1m above the ground
and 1m away from a wall or metal surface to minimize reflections. The
transmitter should also be at least 1m away from a wall or metal surface
to minimize reflections. The transmitter should also be at least 1m away
from the receiver. Keep antennas away from noise source such as
motors, automobiles, neon light as well as large metal objects.
