Your scanner's Close Call feature lets you set the scanner so it detects, alerts you to, and displays
the frequency of a nearby strong radio transmission. You can set the scanner so the Close Call
feature checks for a Close Call hit every 2 seconds in the background while you are scanning,
searching, listening to the weather frequency, etc. or use Close Call Only mode. Close Call
'Do-Not-Disturb' will only check for close call signals when you are not receiving transmissions.
You can also select the frequency band(s) to look for transmissions. When the scanner detects a
Close Call hit, it alerts you according to the alert settings.
'Hits with Scan' is a special system that automatically stores the last 10 Close Call hits until you
cycle power.
The Close Call feature works well for locating the source of strong local transmissions such
as mobile and handheld two-way radios in areas with no other strong transmission sources.
Performance is increased with higher transmit power, a receive antenna tuned to the target band,
and a low background RF level.
The Close Call feature works better with some types of transmissions than others.
It might not correctly display frequency information for transmitters using a highly directional
antenna (such as an amateur radio beam antenna) or if there are many transmitters operating at
the same time in the same area.
