OPEN AND CLOSED MODES
When set to the open mode, the scanner
stops on any ID code and only uses the ID
list to look up ID text tags.
When set to the closed mode, the scanner
stops only on signals that have an ID code
which is found in the ID list for the bank.
Note: When you select a channel manually,
any transmission opens squelch, regardless
of the current mode.
The open or closed mode is set in each
channel storage bank.

When no ID code is programmed into the
scanner, it receives the signal in MOT or ED
mode. In open mode the scanner stops on
any transmission. If the ID is stored, the text
tag appears in the display. Otherwise, the
talk group ID appears in the display. In
closed mode the scanner only stops on a
transmission if the ID is stored. This is very
useful when you want to narrow the scan in
areas where numerous entities utilize the
same trunking system. For example, if the
police department, sheriff’s department, fire
department and EMS all use the same sys-
tem in your area you can program the identi-
cal trunking frequencies on 4 separate
banks. Then by manually storing their re-
spective group IDs into corresponding banks
(i.e. police IDs in bank 1, sheriff’s IDs in bank
2, fire rescue IDs on bank 3, and EMS IDs on
bank 4) and setting the banks to the closed
mode, you can choose which service you
want to listen to. (See “Turning Channel-
Storage Banks Off and On” on Page 25.)

A General Guide to Frequencies
Reception of the frequencies covered by
your scanner is mainly "line-of-sight." That
means you usually cannot hear stations that
are beyond the horizon.
