Using the Close Call Feature

Unlike searching, which requires the scanner to tune to a
frequency to check for a transmission, Close Call RF capture
directly detects the presence of a strong, nearby signal and
tunes to that frequency.
Close Call RF capture works great for finding frequencies at
venues such as malls and sporting events. You can set the
scanner so Close Call detection works "in the background" while
you are scanning other frequencies, turn off normal scanning
while Close Call is working, or turn off the Close Call feature and
use the scanner normally. You can set the scanner so it alerts
you when the Close Call feature detects a frequency. and you
can also set the frequency bands where you want the scanner to
look for transmissions.
The scanner also automatically stores the last 10 hits received
into a temporary bank called "Close Call Hits" in any Close Call
mode. The hits go away when you cycle power. You can also
store these temporary frequencies into channel storage banks.
Close Call capture 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.
However, if you are in an area with many transmission sources
(such as pager radio transmitters, multi-use radio towers,
traffic control devices, etc.), Close Call RF capture might not
find the transmission you are searching for, or it might find a
transmission other than the one you are searching for.
