Thank you for choosing this wireless microphone system!
Our products are designed to last and for user friendly operation. Each system consists of:
1. a receiver
2. a handheld or beltpack transmitter
3. a pair of antennas
4. a switching adaptor
5. an operation manual
For more details, please take a few moments to read this operating manual to have a thorough
understanding of the function and operation of both transmitter and receiver.

Changing CHANNEL / FREQUENCY
This can only be done by pressing UP or DOWN buttons. After a desired channel is selected, it
will be automatically saved and stored into the memory.
CHANNEL scanning
For an interference- free operation, we may need a cleaner channel if the current one receives
too much interference. To perform the scan function, the transmitter must be switched off. After
a channel button is hold pressed for 3 seconds, the receiver will do an auto channel scan
upwards/downwards until it stops at the next cleaner one. Then change the transmitter’s
channel accordingly.
Adjusting VOLUME level
Volume level can be adjusted by rotating the designated volume knob. Clockwise to increase
the volume and counterclockwise to decrease the volume.

Channel synchronizing of the receiver and transmitter
1.To achieve a trouble-free synchronization, please limit the distance between the receiver and
transmitter to within 30cm.
2.Align both sensor areas
3.To change the receiver’s channel, please press the synchronizing button of the transmitter.
The transmitter will transmit synchronizing signal to the receiver and change its channel.
4.To change the transmitter’s channel, please press the synchronizing button of the receiver.
The receiver will transmit synchronizing signal to the transmitter and change its channel.
Adjusting SQUELCH level
The squelch control is on the back of the receiver. When strong interference happens to the
operation, you can use a small screw driver to increase the squelch level by turning the
switcher clockwise. If the interference is too strong even the level is already set to maximum,
the currently in-use channel is not applicable in this location and a change to channel is
recommended.
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 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.
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 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.
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.

Battery installation & indicator
This transmitter 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 transmitter when stored
for a long period. Batteries should be removed from the transmitter before storing without use
for more than 4 weeks.
When the transmitter is switched ON, a red LED will blink once to indicate the batteries
installed are in good condition. If the LED remains illuminated, it means the batteries are
weak and require replacement.

1. Channel setting
Use MENU button to go to the CHANNEL｜FREQUENCY page.︰
After pressing the SET button for 3 seconds, the cursor will flash to allow changes to be made.
Pressing SET / MENU buttons will increase / decrease the channel number. The corresponding
frequency will change accordingly. 3 seconds after selecting a channel, it will be automatically
saved.
2. Battery type setting
Use MENU button to go to the BATTERY TYPE page.︰
After pressing the SET button for 3 seconds, the cursor will flash to allow changes to be made.
Press SET button to select either NiMH (rechargeable battery) or AKLN (alkaline battery). 3
seconds after selecting a battery type, it will be automatically saved.
Remark: NiMH battery must be selected when rechargeable battery is being used. Never
select AKLN (alkaline) when transmitter is intended for charging as alkaline battery isn’t
rechargeable. Wrong battery selection will result in battery sensing electronics to display wrong
and misleading status information.
