SCANNING THE SCAN LISTS

Press

SCAN

to begin scanning the lists you have

stored.

Note: If you have not stored any IDs,

SCAN

scrolls on

the display, but your scanner does not stop on an ac-
tive conversation.

To remove a scan list from active scanning, use the
number keys to enter the scan list’s number. The scan
list number turns off, and the IDs in that list are not
scanned.

Note: One scan list must always be active. You cannot
remove all of the scan lists.

To restore a scan list to active scanning, use the num-
ber keys to enter its number again.

Press

SRC

to return to the scanner’s previous function.

SCANNING TYPE I AND HYBRID
TRUNKED SYSTEMS

Your PRO-91 is set to scan Type II user IDs by default.
When you scan trunked frequencies, each Type II user
ID you see appears as an even number without a dash
(such as 2160). Your PRO-91 can also scan Type I
trunked systems. Each Type I ID appears as a three- or
four-digit number, followed by a hyphen, followed by a
one- or two-digit number (such as 200-14). If you no-
tice a mix of odd- and even-user IDs (such as 6477,
2160, 6481, 6144, and 1167), then you are probably
monitoring either a Type I or hybrid (a combination of
Type I and Type II user IDs) system (see “Types of
Trunking Systems” on Page 39).

You might also notice that you are missing responses
when you hold on an active ID. Unlike Type II systems,
Type I and hybrid systems require a fleet map that sets
specific fleet-subfleet parameters. It is easy to select a
fleet map to scan; what is not always easy is selecting
or programming a map that is being used in your partic-
ular area.
