Using the Close Call Feature
Your scanner's Close Call
TM
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
[SQ/
]
. When the feature is on,
CC DND
or
CC Pri
{insert the two icons here]
and their indicating
icons appear on the display. 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 XX.
•
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.
