also can be programmed as “beeps”), and characters will be displayed on LCD. To turn off the

Press [MONI] button to monitor background noise, and at the same time turn On-Off/VOL

There are four ways the monitor function can be configured. Your dealer can program one of the
following four monitor modes:
•
OFF – No audio is heard when the momentary monitor key is pressed.
•
Monitor Momentary – When using any tone mode decode and a receive signal is present
with an incompatible tone or no tone, audio can be heard when the momentary monitor
key is pressed.
•
Monitor Lock – Same as Monitor Momentary, but the momentary monitor key toggles
the audio function “on” or “off”.
•
SQ OFF Momentary – Receiver audio is heard when the momentary monitor key is
pressed.
SELECT CHANNEL
Turn the channel selector knob to change the channel. The channel number is displayed on LCD.
Turn the knob clockwise, channel number will increase; and turn counter clockwise, channel
number will decrease. The factory or dealer programs the channel frequencies of each channel.
SELECT SQUELCH LEVEL
Hold down the [MONI] button, and then press the [LO] key. The current squelch level code is
displayed on the LCD as shown below. Turn the CHANNEL SELECTOR knob to select the
squelch level and press any key, except the [LAMP] button, to store the setting. The LCD
returns to the origin display.
Note: If the squelch level is set too high, you may not efficiently receive weak signals; if the
level is set too low, you may hear a constant white noise, hear a sputtering noise, or hear
unwanted noises.
