Rotating the Select switch clockwise increases the zone or channel and rotating it 
counterclockwise decreases the zone or channel number. A single beep sounds when the 
channel is changed (if that option is enabled). After the highest zone or channel is 
displayed, wrap-around to the lowest zone or channel occurs and vice versa. If an 
unprogrammed channel is selected, “UNPROGRAMD” is displayed and a tone sounds. 
The radio may also be programmed so that only programmed channels are selected.

The radio can be programmed so that the bar defaults to either the zone or channel display 
when power is turned ON and after a change is made. The delay that occurs before it 
returns is programmed for 1-255 seconds. It can also be programmed to remain in the last 
selected mode.

This programmable feature allows for more than 16 channels in a zone. When enabled 
(using the PCConfigure software), the radio can be configured with up to 16 zones and 54 
channels per zone. This feature forces the radio display to switch the zone and channel 
number indicators. The zone number will be shown on the far right on the display and 
channel number now to the left of the zone number as illustrated in Figure 4.3. The Zone/
Channel Select switch continues to select these functions.

54 Channel/16 Zone Display

The direct Channel Select feature is available if the Channel Select option switch 
parameter is programmed. This feature allows channels to be directly selected using the 
HHC numeric keys or Digital Keypad Microphone. 

For direct selection purposes, channels are numbered sequentially starting with the lowest 
zone. Each zone can be programmed with up to 16 channels, so Zone 1 channels are 
numbered 1-16, Zone 2 channels 17-32, and so on as shown below.
