channels, the channel frequency may be displayed instead of the alias if the Display
Information option switch is programmed.
Figure 4.2 Channel Display
If channel scanning is enabled, the channel number will change to show the current active
channel being scanned. The Channel Identifier Alias will also change to identify the
current active scanned channel.
4.1.6.2 Channel Lock Option
A programming option will lock the channel display during scanning. This feature lets the
radio user always see and confirm the selected operating channel for the radio. The default
is this channel lock is disabled.
When the option is programmed, the channel number will continue to show the selected
channel only. The Channel Identifier Alias will change to show the current scanned active
channel. If the option is not enabled, then the channel number and alias will both change to
indicate the current scanned active channel as described.
4.1.6.3 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.
