Using the Close Call Feature

Your scanner's Close CallTM 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 turn Close Call detection on (CC DND, CC PRI) or Off,

press Func then . 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” on Page 73.
