2-2-2. 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 ▼(down) or ▲(up) 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 ▼(down) or ▲(up) 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.
2-2-3. 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 ▼(down) or ▲(up) button to turn to
the squelch setting page.
2 Hold SET button until this icon
flashes to denote readiness for setting.
3 Press ▼(down) or ▲(up) button to select a
new squelch level between 01 and 10. The
default level is 01.
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 default level (LE-01) and use the scan function to locate a clear, interference-free
channel.
