4.2 RECEPTION

1.Turn the POWER /VOLUME CONTROL knob clockwise to turn the transceiver on.

2.Turn the SQUELCH CONTROL knob fully counterclockwise. This state is known as squelch off.

3.Turn up the POWER /VOLUME CONTROL knob until the noise or audio from the speaker is at a desired level.

4.Select a channel that has no signal being received (no one is transmitting on the channel) and only noise is heard.

5.Slowly turn the SQUELCH CONTROL knob clockwise and stop immediately after the noise disappears. This condition is known as the “Squelch Threshold”. If the knob is turned clockwise past this point, weak signals may not be received. No noise or no signal is heard until a signal is received that exceeds the squelch threshold.
