TO OPERATE THIS SYSTEM...
Simply turn on the transmitter and the receiver: they will automatically
“nd” each other.
1. Adjust the antennae to the best receiving angle (about 90 degrees).
2. Connect the external power plug to the back panel power socket .
3. SYNC frequencies between transmitter and receiver as follows:
A . Manual mode: press Freq/Scan for 1 second till the display icks, then press
Freq/Scan to change group, then press Freq/Scan again for 1 second to choose
the channel.
B. Automatic mode: press Freq/Scan shortly, then display ickers circling, and
automatically sets to the clearest channel.
C. Take off battery cover on transmitter, set the SYNC window towards to
receiver’s SYNC indicator. Press power button briey, while the power display on
the transmitter ickers, meaning a successful synchronisation.
4. To shut down, press power button for 3 seconds.

TROUBLESHOOTING
PROBLEM
No signal (neither receiving nor
sending)
Receiver has no signal
Receiver has RF signal but no AF
signal
The AF signal has too much
background noise
AF signal is distorted
Working distance shorter and signal
unstable
SOLUTION
Battery in transmitter is low or the receiver is
not switched on
The frequency is different between receiver
and transmitter, or over receiver’s range
(SUW35)
The squelch is set too high
Receiving output is too low. Also, there may
be frequency interference.
The frequency deviation of transmitter
adjusts more or receiving output is too high
Receiver’s squelch is set too high, or
the antenna setting of the receiver is
unsuitable. Possibly strong electromagnetic
surroundings.
