adjusted to keep the speaker muted except when a signal is being
received on the frequency that is being monitored.
Note: The functionality of the side ▲ and ▼ buttons can optionally be
set to adjust Squelch all the time. See the Advanced Settings section for
details. These instructions reflect the factory default behavior of the side
▲ and ▼ buttons.
To Set Squelch:
 Push the SQL button.
 Using the ◄ and ► buttons on the keypad or the side ▲ and ▼
buttons, adjust the squelch setting from 0 to 24.
 Setting Squelch to 0 results in static being heard all the time, even
when no signal is being received (no Squelch being applied). This will
drain the battery more quickly.
 Setting Squelch to 24 means that only a signal that is extremely strong
will break Squelch (un‐mute the speaker) and be heard.
 Typically, Squelch is set to the lowest setting that causes all
background noise to be muted, but allows desired transmissions to be
received. The Squelch setting may need to be adjusted in different
environments and conditions.
Exit Setting Squelch mode by:
 Pushing the SQL or CLR buttons on the keypad.
 Waiting a few seconds.
 Pushing the Emergency button.
 Pushing the Push‐to‐Talk button.
The previous menu or mode will then continue.
Note: Squelch can be changed in any mode or menu.
