CHIAYO SDR-8200 - Manual (Page 6)

Operation
Chiayo Transmitters and Receivers have factory preset to allow immediate usage after
switch-on.
However, please note that the transmitter Sensitivity function is dependent on application
such as close proximity singing or tripod mouth speech. To avoid overmodulation and
distortion, please check whether the preset sensitivity level is suitable for your particular
application. For close proximity singing purposes, please select lowest sensitivity level
whereas for tripod mount speech purposes, please select a higher sensitivity level.
If you have made changes to the setting, after making proper selection on Transmitter and
Receiver settings the system is ready for operation. However, both antennas of the receiver
must be installed to assure a good reception.
First switch on the receiver by pressing the Power On / Off switch. The LCD display will show
the information last stored.
Switch on the matching transmitter with the correct matching frequency. The LCD display will
show the information last stored.
The LED RF indicator on the receiver front panel will light up indicating RF signal has been
received. If this is not the case, please check and verify the frequency setting on both
transmitter and receiver. When transmitter is moving around, the Diversity A B switch will light
on alternately to indicate the stronger reception on either A or B antenna.
When voice is spoken into the microphone, the LED AF indicator on the receiver front panel
will light on and flashes according to the intensity of the AF signal.
There are two different audio outputs at the rear side of the receiver: Balanced ( Microphone
level ) and Unbalanced ( LINE level ). Please select the matching output to match the input of
the connecting Mixer or Amplifier.

least 1m above the ground and at least 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, as
