CLOSE CALL
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 nding 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 o normal
scanning while Close Call is working, or turn o 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,
trac control devices, etc.), Close Call RF capture might not
nd the transmission you are searching for, or it might nd a
transmission other than the one you are searching for.
