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.
Important! There are many options and settings in Search/Close Call Options
that affect and compliment the settings for Close Call. Please review those first.
