Setting Volume and Squelch
SQUELCH sets the minimum signal level that must be present for
the HTX-242 to amplify the signal through the speaker or to stop
when scanning. Follow these steps to set the squelch.
1. Rotate SQUELCH fully counterclockwise.
2. Set VOLUME so you can hear the background hiss between
transmissions.
Note: If you do not hear hissing, turn TUNE/M-CH to select a
frequency that does not have communications in progress.
3. Slowly turn SQUELCH clockwise until the hissing stops.
If you turn SQUELCH too far clockwise, you might miss parts of
transmissions. If you do not turn SQUELCH far enough clockwise,
you hear hissing between transmissions and the HTX-242 might
not scan properly.
