Radio Shack 20-163 manual Scanner Setup, To set the attenuator mode

Page 14

With the attenuator on, the scanner might not receive weak signals. You can reduce interference using two attenuator modes:

•Global – (Default) The attenuator setting is applied to all channels, bands, or groups.

•Normal – Lets you set the attenuator in each channel, band, or group.

You cannot set the attenuator while scanning.

To set the attenuator mode:

1. To set Global mode, press FUNC and then ATT. On the display “G” appears.”

2. To set the attenuator for each channel, press FUNC and then ATT. On the display “G” disappears. For each channel:

•On – Press ATT. “A” appears.

•Off – Press ATT again. “A” disappears.”

Scanner Setup

A frequency, expressed in kHz or MHz, is the tuning location of a station.

Your scanner saves frequencies to channels and groups the channels into banks. The scanner’s 10 banks each hold 100 channels (1,000 channels total).

The scanner is preset to the most common AM or FM receive modes for each frequency range. However, some amateur transmissions may operate in a different mode. If the transmission sounds weak or distorted, you may have the channel set to the wrong receive mode:

AM – Amplitude Modulation, primarily used for aircraft, military, some amateur and government transmissions.
