Monitor Speaker Volume Levels
The monitor speaker volume levels are the levels for the various functions heard through the optional monitor
speaker. All adjustment controls are located on the base station circuit board. Turn the controls clockwise to
increase the volume and counterclockwise to decrease volume.
To set the monitor speaker volume levels:
1. Set the master MON VOLUME control to the midrange position.
2. With a vehicle detected at the menu sign (alert tone sounding), adjust the MON ALERT control so that the
alert signal coming through the monitor speaker is at a suitable level.
3. Press and hold the headset
T
alk switch and speak into the headset microphone. Adjust the MON TALK
control so that the talk audio coming through the monitor speaker is at a suitable level.
4. Press the headset
P
age switch and speak into the headset microphone. Adjust the MON PAGE control so that
the page audio coming through the monitor speaker is at a suitable level.
5. While you listen to audio coming from the menu sign, adjust the MON IN control so that the menu sign audio
coming through the monitor speaker is at a suitable level.
*Note
If any monitor functions are not desired by the customer, turn the related adjustment control fully
counterclockwise to silence the function.

Listen Level (Menu Sign Microphone Sensitivity)
The listen level is the volume of the menu sign audio heard in the headset.
To set the listen level:
1. Turn the headset/belt pack off and then on. (This sets the volume control to midrange.)
2. Have someone drive a vehicle up to the menu sign. When the vehicle is detected, you will hear the vehicle
alert tone in the headset/belt pack.
3. Press and release the headset
T
alk switch to cancel the alert tone and allow you to listen to the audio from the
menu sign.
4. Adjust the MENU MIC SENS level control for the desired volume (clockwise to increase volume;
counterclockwise to decrease.)
The Listen Level should now be properly adjusted. Because the headset/belt pack volume control was set at
midrange, there will now be enough range (up/down) in the headset/belt pack volume control to allow operators to
set the headset volume to a preferred level.
Menu Sign Talk Volume Level
The menu sign talk volume level is the volume of the headset/belt pack audio heard at the menu sign.
To set the menu sign talk volume level:
1. Move the DAY/NIGHT switch on the base station to the DAY position.
