UNDERSTANDING BANKS
Channel Storage Banks
To make it easier to identify and select the channels you
want to listen to, channels are divided into 10 banks (0–9)
of 50 (00 to 49) channels each. Use each channel-stor-
age bank to group frequencies, such as those used by
the police department, fire department, ambulance ser-
vices, or aircraft (see “Guide to the Action Bands” on
Page 67). For example, the police department might use
four frequencies, one for each side of town. You could
program the police...

UNDERSTANDING YOUR 
PRO-92’S MODES
You can program each channel with any of seven receive
modes. Each 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 “Open and Closed
Modes” on Page 63). The following sections describe
each mode and how they affect your scanners operation.

With few exceptions, such as the VHF Aircraft and Ma-
rine bands, almost every other VHF or UHF radio system
uses some form of coded squelch. By far, PL is the most
popular mode among non-trunked systems. For most
scanning use, try setting PL mode for all non-trunked
channels. If you operate the bank in open mode, the
scanner will display the appropriate code.
AM Mode
This sets the scanner to receive transmissions using am-
plitude modulation (AM). AM is used for aircraft, military,
some amateur...

When the scanner receives a transmission on a channel
set to the PL mode, it first decodes the PL tone included
with the transmission. In the Open mode, the scanner
stops on the transmission and displays the PL tone on
the bottom line of the display (or displays None if no tone
is included). In the Closed mode, the scanner only stops
on the transmission if the PL tone matches the tone that
you specified for the channel.
PL tones range in frequency from 67 Hz to 254.1 Hz. You
select a PL tone by...
