data matches a talk group ID that you have stored in the talk group ID list and have
not locked out. LTR systems are frequently programmed so that each radio has a
unique user ID.
Startup Configuration
Setup/Operation
The Startup Configuration option lets you quickly and automatically lock and
unlock systems based on your desired configuration. Simply hold down a number
button while powering on the scanner or while the opening screens are displayed.
Systems assigned to that number are automatically unlocked and systems
assigned to other numbers are automatically locked. Systems that are not
assigned to any startup configuration are left unchanged.
You could use this feature to give you quick, single-press Quick Key access to
your favorite systems even when you travel to other locations. For example, if you
program your scanner as follows:
When you are in the Fort Worth area, press [1] while turning on the scanner.
System Quick Keys [1], [2], and [3] then allow you to select between the local
systems. When you travel to the Phoenix area, hold [2] while turning on the
scanner. Now, the Fort Worth systems are locked out and System Quick Keys [1],
[2], and [3] allow selection between the Phoenix-area systems.
Multi-Site Trunking
Some systems covering a very large geographic area use multiple antenna sites
that each operate on different frequencies, but that use the same Talk Group ID’s
for traffic. When programming such a system, you program each site’s frequencies
and other settings into the system, then program the channels into channel groups
within that system. Each site can have its own quick key, so you can turn each
individual site on or off while you scan. Since all sites share all the channels within
the system, multi-site trunking is much more efficient than programming each site
as a separate system.
