Using the Close Call Feature

Your scanner’s Close Call™ feature lets you set the scanner so it detects, displays

the frequency 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 [SQ/C]. When the feature is on, CC DND(

c) or

CC Pri(C) and their indicating icons appear on the display. Using CC Priority,

normal operation is briefly interrupted about every 2 seconds.

Notes:

• 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 96.

• 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.

• The “Close Call” mode can detect frequencies on the default band step only.
