Changing CHANNEL / FREQUENCY
1. Press-release SET button until the CHANNEL-FREQUENCY page appears.
2. Press ▲(UP) or ▼(DOWN) button to select a new channel. As the channel changes, the
frequency changes accordingly, too.
3. After a channel is chosen, wait 5 seconds to store the setting.
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.
1. Press-release SET button until the AUTO SCAN page appears.
2. Press ▲(UP) or ▼(DOWN) button to find and locate a clear, interference- free channel.
3. After a channel is chosen, wait 5 seconds to store the setting.

Adjusting VOLUME level
1. The setting can be made right on the homepage.
2. Press ▲(UP) or ▼(DOWN) button to choose a new level.
3. After the setting is made, wait 5 seconds to store the setting.
Adjusting SQUELCH level
When interference is encountered try reducing the sensitivity of the receiver, thus less
susceptible to interference.
1. Press-release SET button until the SQUELCH SETUP page appears.
2. Then press ▲(UP) or ▼(DOWN) button to choose a new level between 1 and 10.
3. After a level is chosen, wait 5 seconds to store the setting.
Since increasing the squelch level will also reduce the reception distance, it’s recommended to
choose the lowest level that can eliminate the interference.
If this still does not solve the problem it means this frequency is not suitable. Adjust the squelch
back to its preset level and use the scan function to locate a clear, interference-free channel.
Receiver installation
1. 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.
2. 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.
3. 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.
Unbalanced 6.3mm phone jack connection
Balanced XLR connection
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 microphone requires 2 x AA batteries to operate.
To install, remove the battery cover and slide the batteries according to the correct polarity 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 if it is not to be used for a
prolong period of about 4 weeks or more.
When the microphone is switched ON a blue LED②will blink once to indicate the batteries
installed are in good condition. If the LED remains illuminated, it means the batteries are
weak and a replacement is required.
Channel setting
1. Use MENU button⑤to go to the CHANNEL｜BATTERY STATUS page.
2. The upper-right channel number will flash to allow changes to be made.
3. Press SET button to change the channel number.
4. 5 seconds after selecting a channel, it will be automatically saved.
Battery type setting
1. Use MENU button⑤to go to the BATTERY TYPE page.
2. Press SET button⑥for 3 seconds, then the cursor “←”will flash to allow changes to be
made.
3. Press SET button to select either NiMH (rechargeable battery) or AKLN (alkaline battery).
4. 5 seconds after selecting a battery type, it will be automatically saved.
Important: NiMH battery must be selected when rechargeable battery is being used. Never
select AKLN (alkaline) when microphone 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.

Instructions
Tips to obtain the best results for a wireless microphone system
1.For transmitter, please use only fresh alkaline battery. Do not use general purpose (carbon
zinc) battery.
2.Transmitter and receiver should be as close as possible, but not less than 1m.
3.Position the receiver so that it has the least possible obstruction between it and the
transmitter. Line of sight is best.
4.If external antenna is used, low loss RF shielded cable should be used and the length of the
cable should not exceed 3m.
5.The receiver antenna should be kept as far away as possible from any metal surface.
6.A receiver can not receive signals from two transmitters at the same time.
7.Turn off the transmitter when not in use. Remove the battery if the transmitter is not to be
used for a period of time.
8.If the volume Control of the receiver is set too high, it may over-drive the input of the mixer,
causing distortion. Conversely, if the receiver output is set too low, the overall signal to noise
ratio of the system may be reduced. Adjust the output level of the receiver such that highest
sound pressure level going into the microphone causes no input overload in the mixer, and
yet permits the mixer level controls to operate in their normal range (not too high or too low).
This provides the optimum signal to noise for the entire system.
Simple DIY trouble shooting:
Case 1: Transmitter is on, Receiver is on, but no RF signal received.
1-1 Transmitter and Receiver are having different frequencies.
If in this case, please change either transmitter or receiver to the same frequency. This can be
easily done by its unique function of frequency synchronization.
1-2 Transmitter is faulty
When step 1 is verified to be correct, then either Transmitter or Receiver is faulty. To prove this
transmitter is faulty, please use another functional transmitter (if any) of the same model and
same frequency to switch on the receiver, If this transmitter of the same frequency could trigger
on the receiver, then this proves that the other transmitter is faulty. Send it back to CHIAYO's
authorized agent for service.
1-3 Receiver is faulty
When steps 1 & 2 failed to bring any result, then the receiver could be faulty. To verify, please
use another functional receiver (if any) of the same model and same frequency to double check
and send it back to CHIAYO's authorized agent for service.
Case 2: Transmitter could not be switched on.
Battery is weak or wrongly installed. Please check the batteries to see whether to recharge or to
replace them.
Case 3: Strong interference signal received.
If interference could not be solved by adjusting the squelch (SQ) control to maximum, please
stop using the current frequency. Please operate the SCAN function of the receiver to search
for the next cleaner frequency
