•
When the feature is on,
appears on the display
and normal operation is briefly interrupted about
every 2 seconds.
Notes:
•
CC DND (Do Not Disturb)
- The scanner checks for a
Close Call hit every 2 seconds only if the scanner is
not currently stopped on a transmission. If the
scanner is on a transmission the scanner waits until
the signal ends to perform a Close Call check. This
prevents breaks in audio during Close Call checks.
•
CC PRI
- Close Call works even if there is a
transmission. Checks for a Close Call hit every 2
seconds.
• 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. Several factors affect
Close Call performance, however. Performance is
increased with higher transmit power, receive
antenna tuned to the target band, and a low
background RF level. Other than the antenna, you
have no control over these factors, but they explain
why performance might vary by both location and time.
• The Close Call feature cannot detect satellite dishes
or any transmitter with a frequency above or below
the frequency ranges listed under “Setting Close Call
Options” in the next chapter.
• 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.
