Trunk Search And Scan; Type I And Hybrid Trunked Systems - Radio Shack PRO-433 Quick Start Manual

Trunking Operations

trunk search and scan

You can trunk scan and scan conventional frequencies at the same
time. You can program conventional frequencies in the same bank
as trunking systems, but not while in trunk mode.
To scan both trunking and conventional banks, turn off trunking,
select the banks to scan, then turn on trunking again.
To switch to trunk modes while scanning conventional frequencies,
complete the following steps:
1
. Press TRUNK. The scanner begins scanning both trunking and
conventional banks.
2
. Hold down TRUNK for about 1 second. The scanner switches
to the trunk scan mode.
3
. Hold down TRUNK for about 1 second again. The scanner
switches to the trunk search mode.
To identify a trunked frequency while scanning or searching,
press . The frequency fl ashes twice. Then hold down
confi rmation tone sounds and the ID and the frequency alternate.
To return to normal operation, press .

type I and hybrid trunked systems

Your scanner is preset to scan Type II system IDs. When you scan
trunked frequencies, each Type II user ID appears as an even
number without a dash (example 2160). Your scanner 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 (example 200-14).

NOTES
•
If you notice a mix of odd- and even-user IDs (examples
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 with
the S-Bit function turned off.
If you consistently miss responses even with scan
delay, change your default system type or fl eet map.
