Talk Permit Tone - When enabled, a short tone
sounds after a request for a group call has been
approved by the main controller. This indicates that
speaking can begin. When disabled, no audio feed-
back is used to indicate when speaking can begin.
System Scan - Selects the Priority Monitor Scan list
selected by the channel (see “Priority Monitor Scan
Screen” description in Section 3.6.7). If “No Scan
List” is programmed, scanning is not selectable on
that channel.
Auto Scan - When enabled and a channel is selected,
the radio automatically begins scanning the scan list
associated with that channel. When disabled, scan-
ning can only be started manually by the Scan option
switch.
