Squelch

The squelch is used to eliminate any annoying background noise when there

are no signals present.

Make sure to rst select a channel not in use before setting the

squelch in your PM-500 SWF VHF Marine radio.

S1 - max sensitivity (min squelch)

S2 - med sensitivity (med squelch)

S3 - min sensitivity (max/tight squelch)

1. Press SQL/UIC momentarily. S shows on the

display and the current squelch level will ash.

2. Press SQL/UIC while the squelch level shows to

change the squelch level to the next step.

3. Press and hold SQL/UIC to save and exit the

squelch setting.

Think of squelch as a gate. If you increase

the squelch level to maximum it raises the

‘Squelch gate’ so only the strongest sig-

nals get through.

If you decrease the squelch level to mini-

mum it lowers the ‘Squelch Gate’ to the

extent that weak signals can get through.
