Radio Shack PRO-92 owner manual AM Mode

Page 25

You can set each of the scanner’s channel storage banks to open or closed mode.

In open mode, the scanner scans signals transmitted in all systems. In closed mode, the scanner scans signals transmitted only under the following conditions:

•When the signals are in the FM mode.

•When the signals are in the LT, MO, or ED mode and the signal's ID code matches the programmed ID code.

•When the signals are in the PL or DPL mode and the signal's ID code matches the programmed ID code.

Note: When the signals are in the PL or DPL mode, the scanner receives all signals on a channel when the ID code is set to NONE.

You can also select the users or talk groups you want the scanner to receive in closed mode.

When you set a channel storage bank to open mode, + (open) appears under the bank’s number while scan- ning. When you set a channel storage bank to closed mode, – (closed) appears under the channel storage bank's number while scanning. Or, OPEN or CLOSED appears while the scanner is in manual mode or while the scanner is receiving a signal during scanning.

See “Changing the Open/Closed Mode” on Page 58 for more information about setting the open and closed modes.

AM Mode

This sets the scanner to receive transmissions using am- plitude modulation (AM). AM is used for aircraft, military, some amateur radio, and some government transmis- sions. When the scanner receives a transmission on a channel set to the AM mode, it always stops on the transmission.
