Question:  What user functions can be controlled via the base station's front panel channel display / control? 
Answer:  Front Panel Channel Display screen. The following default information is displayed onscreen:






• The channel label (user can create custom names for each of the 4 channels available)
• The channel listen (volume) level (volume bar increases / decreases depending on volume level set)
• The number of people listening and talking on the channel (show by the L and T letters followed by a numerical value)
