TRANSCEIVER PROGRAMMING

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.
