2.Press the SQL key, then press 
(Down) key until squelch level is minimum. This state is known as squelch off.
3.Select a channel that has no signal being received (no one is transmitting on the channel) and only noise is heard.
4.Turn up the POWER SWITCH/VOLUME CONTROL knob until the noise or audio from the speaker is at a desired level.
5.Press the SQL key, then press the 
(Up) key and stop immediately after the noise disappears. This condition is known as the “Squelch Threshold”. If the 
(Up) key is pressed beyond this level, weak signals may not be received. No signal can be heard until a signal is received that exceeds the squelch threshold. The SQUELCH ADJUSTMENT mode will automatically turn off in about 5 seconds. To turn off the SQUELCH ADJUSTMENT mode immediately, press the SQL key.
6.To change channels, press the 
(Up) or
