Using Trunk Tracking Scan Delay

Many trunked systems have a period of 2 or more seconds between a query and a reply. You can program a 5- second delay so the scanner holds on an ID for 5 seconds to wait for a reply. The scanner continues to monitor the frequency for 5 seconds after the transmission stops before resuming scanning.

Press DELAY to turn trunk tracking scan delay on or off. DELAY appears when trunk tracking scan delay is set.

Note: If you consistently miss re- sponses even with trunk tracking scan delay set, you might need to change the default system type or the fleet map you are using. See “Scanning Type I and Hybrid Trunked Systems” on Page 33.
