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 batteries 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 study 1: transmitter is on, receiver is on, but no RF signal received.
1-1. Transmitter and receiver are having different frequencies. In this case, please adjust
either transmitter and receiver to the same channel.
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 transmitter (if available) of the same model and
same frequency to switch on the receiver. If this transmitter can function with 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 receiver (if available) of the same model and same frequency to double
check and send it back to Chiayo's authorized agent for service.
Case study 2: transmitter could not be switched on.
The battery is weak or wrongly installed and please replace or recharge the batteries.
Otherwise, please check according to 1-2 above.
Case study 3: strong interference signal received.
If interference could not be solved by adjusting the squelch (SQ) control to maximum,
Please stop using this channel and change to another one.
