When no signals are present, the squelch on the transceiver 

automatically mutes the speaker so you will not hear 

background noise.  Using the MON key, you can open the 

squelch to unmute the speaker.  This allows you to:

•  confirm the channel activity so you don’t make a call while another 

party is using the same channel

•  adjust the volume level without having to wait for a call
•  listen to an intermittent call (due to a weak signal) without it 

continuously cutting out

To manually open the squelch, press and hold the MON key.

•  When squelch is open, the   icon appears on the display and the 

LED lights green.

To return to normal operation, release the MON key.

You can adjust the default squelch level of the transceiver.

  With the transceiver power OFF, press and hold the MENU 

key while turning the transceiver power ON (for 1 second).

  Press the   or   key to select “Sq”.

  Press the MENU key then press   or   to select “Sq- 0” 

(open), “Sq- 1” (default setting), or “Sq- 2” (tight).

  Press the MENU key to confirm the selection.

  Press the PTT, MON, or CAL key to exit Setting Mode.
