receiver’s LED will become the
same as the transmitter’s, which
means the receiver has been
successfully synchronized.

transmitter’s LCD will become
the same as the receiver’s,
which means the transmitter has

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.

CHANNEL scanning
For an interference- free operation, a cleaner channel might be necessary
if the current one receives too much interference. To operate the scanning:
1 Press ▲(up) or ▼(down) button to make the frequency icon
appear on the bottom.
2 Hold SET button until this icon flashes to denote
readiness for setting.
3 Press ▲(up) or ▼(down) button to find and locate a clear,
interference- free channel.
4 After a channel is chosen, press SET button or wait 5 seconds
to store the setting.

SQUELCH (SQ) setting
When interference is encountered try reducing the sensitivity of the
receiver, thus less susceptible to interference. To operate the squelch
setting:
1 Press ▲(up) or ▼(down) button to turn to the squelch setting
page.
2 Hold SET button until this icon flashes to denote
readiness for setting.
3 Press ▲(up) or ▼(down) button to select a new squelch level
between 1 and 10.
4 After a level is chosen, press SET button or 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.
