10 banks (ò to é) of 30 (òò to ðé) channels each, a total of 300 channels. You can use each channel-storage bank to group frequencies, such as those used by Mo- torola trunking, EDACS trunking, Marine, CB, Police, Fire, Aircraft and Ham (see “Typical Band Usage” on Page 67).

For example, a police department might use four fre- quencies, one for each side of town. You could program the police frequencies starting with òòò (the first channel in bank 0) and program the fire department frequencies starting with ñòò (the first channel in bank 1). The first digit identifies the bank (ò to é). The second and third digits identify the channel within the bank (òò to ðé).

Search Banks

Your scanner has five preprogrammed search banks and one limit search bank. You can set the lower and higher frequency limit in the limit search bank. (For the default setting, see “Searching a Preprogrammed Fre- quency Range” on Page 30).

UNDERSTANDING YOUR SCANNER'S MODES

You can program each channel with any of four receive modes (AM, FM, MOT, and ED). However, you can not program MOT (Motorola), or ED (EDACS) mode in VHF. Each receive mode affects how your scanner operates when scanning and receiving transmissions, and also af- fects what transmissions you receive when you set the scanner to the closed mode. See “Changing the Receive Mode” on Page 46.

AM Mode

The AM mode sets the scanner to receive transmissions using amplitude modulation (AM), primarily used for air- craft, military, some amateur radio, and some govern- ment transmissions. (Refer to “Specifications” on Page 81 for a list of the frequencies covered.) When the scanner receives a transmission on a channel set to the AM mode, it always stops on the transmission.
