SYSTEM AND GROUP SCANNING

SYSTEM AND GROUP SCANNING

General

Introduction

The scan feature monitors, in sequence, the systems and/or groups in the scan list. When a message is detected that the transceiver is programmed to receive, scanning stops and the message is received. Shortly after the message is complete, scanning resumes (unless it has been disabled). System and group scanning or group scanning only may be used (see next page), and the operation of each type is as follows. Refer to page 23 for more information on systems and groups.

System Scanning - Detects calls on all systems in the system scan list. If system scanning is not used, calls are detected on only the currently selected system.

Group Scanning - Detects calls on all groups in the group scan list. These groups are from the selected system and also from scanned systems if system scanning. If group scanning is not used, calls are detected on only the selected group. In addition, calls may be detected on higher priority LTR-Net and LTR groups (see “Priority Calls” on page 45).

Scan On-Off

System and/or group scanning are turned on and off by pressing FCN SCAN. When either type of scanning is enabled, is indicated in the display (see following illustration). Then when group scanning is actually occurring, dashes are displayed instead of a group number (if the numeric display mode described on page 20 is selected). Group scanning is not indicated if the alpha display mode is selected, and system scanning is never indicated. The monitor mode must be disabled for scanning to occur (see page 49).
