General Operation
3.4.2 Zone / Channel Select
The front panel Select switch is used to change the zone and channel. Pressing this switch
toggles between the zone and channel select modes, and rotating it changes the zone or
channel. An optional beep can be programmed to sound when the switch is pressed or the
channel is changed.
The current mode is indicated by the bar over the zone or channel display. For example,
when the bar is over the zone display (see following illustration), the zone select mode is
enabled.
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.
3.4.3 Direct Channel Select
The direct Channel Select feature is available with the Handheld Control Unit (HHC)
only, and if the Channel Select option switch parameter is programmed. This feature
allows channels to be directly selected using the HHC numeric keys or Up/Down switch.
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. For example, Zone 1/
Channel 16 is selected by Channel 16, and Zone 2/Channel 16 is selected by Channel 32.
