SQUELCH (SQ) setting
When interference is encountered try reducing the sensitivity of the receiver, thus less
susceptible to interference.
1.
Press-release the menu/up button
until
the squelch icon
appears on the
bottom.
2.
Hold setting/down button
until this icon
flashes to denote readiness for
setting.

►
3.
Press menu/up button
or setting/down
button
to select a new squelch level
between 1 and 10 (
: forward,
:
backward).
4.
After a level is chosen, wait 5 seconds to
store the setting.
►
Important
: 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.
CHANNEL SYNCHRONIZING between receiver and transmitter
Align infrared areas of the receiver and transmitter within 10~30cm.
1.
Press the synchronizing button of the
receiver.
2.
The receiver will transmit the frequency to
the transmitter and synchronize the
channels.
If it doesn’t work check that you have the IR sensor panels aligned, that they are facing each
other, devices are within 10~30cm of each other, and try again.
