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, 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 0-99 seconds. It can also be programmed to remain in the last
