Adjusting the squelch level
The IC-M1 has a squelch even
though there is no control knob for
it. In order to receive signals prop-
erly, as well as for scan to func-
tion, the squelch must be
adjusted to a suitable level.
1
While pushing [SQL], rotate the channel selector.
- The first click of the channel selector indicates the current
squelch level.
- There are 5 squelch levels to choose from: 0 is completely open;
4 is the maximum squelch level.
2
Release [SQL] when the desired squelch level is indicated
in the function display.
NOTE: The squelch level 1 is designed for receiving weak
signals so that the squelch delays to close. If you want to
cut the squelch noise, set the level to 2 or more.
