CHANNEL scanning
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.
First, press "SET" till the display shows .
Then press UP or DOWN to go to the next clean channel.
After the setting is made, the data will be automatically saved.
CHANNEL SYNCHRONISING of the receiver and microphone
a.Limit the distance between the receiver and microphone within 30cm.
b.Align both infrared areas
c. To change the receiver’s channel, please press the synchronising button of the microphone.
The receiver’s channel will be changed to the same channel as the microphone.
d.To change the microphone’s channel, please press the SYNC button of the receiver and
will appear on the receiver’s display, followed by
indicating data transferred. Please try again if appears.

Receiver installation
For best operation, the receiver should be at least 1m above
the ground and 1m away from a wall or metal surface to
minimise reflections. The transmitter should also be at least
1m away from a wall or metal surface to minimise 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.
Audio output connection
There are two audio outputs on the back of the receiver, Mic-level balanced and Line-level
unbalanced. 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 (LINE OUT) from the receiver to the amplifier/mixer. If
the amplifier/mixer has an XLR input, connect a cable from the balanced XLR audio output
(MIC OUT) from the receiver to the amplifier/mixer input.
Rack mounting
The receiver can be cabinet-mounted by either one or two units. If only one receiver is to be
mounted, an optional kit is available and it's installed as shown in Fig 1. If two receivers are to
be mounted, they can be assembled by another kit and installed as shown in Fig 2.

2. Battery power LED
3. Power switch
4. LCD
5. Menu button
6. Setting button
7. IrDA synchronising button
8. Battery compartment
9. Color cap
10. IrDA sensor area
Battery installation & indicator
This microphone requires 2 x AA batteries to operate.
To install, remove the battery cover and slide the batteries into the battery compartment &
replace the battery cover.
Note: Batteries contain a corrosive acid that may leak and damage the microphone when
stored for a long period. Batteries should be removed from the microphone before storing
without use for more than 4 weeks.
When the microphone is switched ON a red LED (2) will blink once to indicate the batteries
installed are in good condition. If the LED remains illuminated the batteries have expired
and require replacement.
Channel synchronising of the receiver and microphone
1. Limit the distance between the receiver and microphone within 30cm.
2. Align both sensor areas
3. To change the receiver’s channel, please press the synchronising button of the microphone
and will appear on the LCD. If the receiver’s channel is synchronised,
will appear. Otherwise, please try again if the LCD shows .
4. To change the microphone’s channel, please press the synchronising button of the receiver.
