Operating Procedure:
1. Press the rotary controller  to activate and move the cursor to the SQ parameter.
When the SQ cursor starts to flash, the squelch level is ready to be set.
2. Rotate the rotary controller clockwise to increase the SQ level; counterclockwise to
decrease the level.
3. Press the rotary controller once to confirm and save the selected SQ level or wait 5
seconds (without touching anything) and the parameter will automatically be saved.
NOTE: The higher the level indicators, the lower the sensitivity - which shortens the
transmission range. The lower the level indicators, the higher the sensitivity
which increases the transmission range. However, when the SQ is set at full
level (5 bars), the "AutoScan" function will be disabled and users can freely
select any group or channel manually.
