Manual Tuning — allows you to manually scan through the entire range of available frequencies without programming. (See “Specifications” on Page 52 for a list of the available frequency ranges.)

Weather Radio — allows you to listen to NOAA weather broadcasts without program- ming. See “Listening to the Weather Band” on Page 23.

UNDERSTANDING BANKS

Channel Storage Banks

A bank is a storage area for a group of chan- nels. Channels are storage areas for fre- quencies. Whereas a channel can only contain one frequency, a bank can hold nu- merous channels.

To make it easier to identify and select the channels you want to listen to, your scanner divides the channels into 10 banks (ò to é) of 30 (òò to ðé) channels each, a total of 300 channels. You can use each channel-stor- age bank to group frequencies, such as those used by Motorola trunking, EDACS trunking, Marine, CB, Police, Fire, Aircraft and Ham (see “Typical Band Usage” on Page 40).

For example, a police department might use four frequencies, 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 set-

ting, see “Searching a Preprogrammed Fre- quency Range” on Page 18).

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 (Motor- ola), or ED (EDACS) mode in VHF. Each re- ceive mode affects how your scanner operates when scanning and receiving trans- missions, and also affects what transmis- sions you receive when you set the scanner to the closed mode. See “Changing the Re- ceive Mode” on Page 28.

AM Mode

The AM mode sets the scanner to receive transmissions using amplitude modulation (AM), primarily used for CB, aircraft, military, some amateur radio, and some government transmissions. (Refer to “Specifications” on Page 52 for a list of the frequencies cov- ered.) When the scanner receives a trans- mission on a channel set to the AM mode, it always stops on the transmission.

FM Mode

The FM mode sets the scanner to receive transmissions using frequency modulation (FM), used for most public safety transmis- sions, as well as broadcast, business, and amateur radio transmissions. When the scanner receives a transmission on a chan- nel set to the FM mode, it always stops on the transmission.

Motorola Mode

You can set your scanner so it decodes the talk group IDs used with Motorola trunking systems. This setting is called the Motorola mode.
