Adjusting the Squelch
The Garmin Signal™ VHF radio sets the squelch level automatically to filter out static noise. To listen for weak VHF signals that might not break squelch, you can set the squelch level manually.

The manual squelch setting applies only to the current channel. When you switch channels and return to the original channel, the saved manual squelch setting persists.
You can return to the squelch screen and select Auto to restore automatic squelch for the current channel. You can reset all squelch levels to restore automatic squelch for all channels (Restoring Factory Default Settings).
