Preprogrammed Systems and Lockout Options
Preprogrammed Systems and Lockout Options
Your scanner is preprogrammed with over 500 channels covering police, fire, and
ambulance operations in the 25 most populated counties in the US. The following
list details the preprogrammed information.
By default, only the Nationwide systems are unlocked, and your scanner begins to
scan them when you turn it on. To speed up scanning, you can lock out systems
that are beyond your reception area (typically no more than 25 miles using the
supplied antenna). Suggestion: Do not unlock all the preprogrammed sites. You
may wish to lock all the sites and unlock only those in your area by using their
Quick Key.
Follow these steps to lock out systems.
1. Press and hold .
2. While continuing to hold , rotate the Scroll Control to select a system you
want to lock out.
3. While continuing to hold , press [L/O] to lock out the system.
4. Repeat Steps 2, and 3 to lock out additional systems.
The preprogrammed systems provide a starting point; you will want to find out
more information about your local radio systems so you can customize the
programming to better suit your listening preferences.
Notes:
• The list is subject to change.
• You might hear transmissions on frequencies assigned to very distant stations.
This will happen if a local system also uses the same frequency. Disregard the
text tag for these transmissions (e.g. if you are in California, you aren’t really
receiving Florida transmissions even if the scanner displays Dade County).
• To free up memory, delete systems that you will not be monitoring.
• Data used for the preprogrammed information was supplied courtesy of
