5. SET-UP CONSIDERATIONS 
It is important to set the volume control on the radios to the appropriate levels during initial set-
up. Setting them too high will cause considerable distortion within the system. The input 
circuitry was designed to use audio from the speaker output jack with the volume control set to 
comfortable listing level using the radio’s internal speaker. This normally occurs with the 
radio’s volume control set to the 9 or 10 o’clock position. When properly set, the appropriate 
activity LED on the ACS panel will blink on received voice peaks when the radio is NOT 
selected (panel volume control pushed in and not selected for transmit). An easy way to set the 
radio volume is to tune the radio to an unused channel and open the squelch. With the radio 
NOT selected, increase the radio’s volume on noise until the activity LED just lights steady on. 
The volume control on the radio can then be marked to easily return to this setting if 
inadvertently moved.
