Using the Close Call Feature
Your scanner’s Close Call™ feature lets you set the scanner so it detects, displays
the frequency of, and lets you hear a nearby strong radio transmission. You can set
the scanner so the Close Call feature works “in the background” while you are
scanning other frequencies, turn off normal scanning while the Close Call feature 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 finds a frequency. You can
also set the frequency band where you want the scanner to look for transmissions.
To toggle Close Call mode, press . When the feature is on, ( ) or
( ) and their indicating icons appear on the display. Normal operation is
briefly interrupted about 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 the Set CC Bands:
option on Page 102.
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.
Next, turn the Scroll Control to select an option.
