Using Signal Attenuation

You can use the Signal Attenuation feature in the manual, search, or Scan Mode.

When the ATT indicator is on, the incoming signal strength is attenuated (reduced) by about 14 dB. This prevents unusually strong signals from over-loading the scanner.

In the Scan Mode, you must individually program each channel you want to use the Signal Attenuation feature.

In the Search Mode

1.Set the search limits and press EJ .

See "The Search Mode" on Page 27.

2. Turn Signal Attenuation on.
