WITH YOUR TRANSCEIVER

2. Make sure your antenna is securely connected to the antenna connector.
3. Make sure the SQUELCH control is turned fully counterclockwise.
4. Turn on the unit and adjust the volume control.
5. Select your desired channel.
6. To transmit, press the PTT button and speak in a normal tone of voice.

SQUELCH

The squelch function cuts out annoying background noise when no signal is being
received. To do this, set the channel selector to a channel where no signals are pre-
sent or wait until signals cease on your channel.
MIDLAND M-20 is supplied with two types of squelch: manual and automatic.
Manual: rotate the squelch knob in a counter-clockwise direction and stop be-
fore you hear a 'clic', then rotate it clockwise to the point where the
background noise just stops. Do not set the squelch too high, other-
wise weak signals will not be able to open the squelch circuit.
Automatic: rotate completely the squelch knob counter-clockwise and stop after
you will hear a 'clic . Now the squelch will be automatically adjusted
according to the background noise.
