PRO51.1

There is an interesting test mode in the PRO-51 that, combined with the direct
search feature of the scanner, lets you pick up out-of-band frequencies. You
will have full access to the 66-88 Mhz ranges as well as the cellular base
range of 869-896 Mhz.

Actually, there are several test modes in the PRO-51 (most of these comments
should be true for any Uniden-made Radio Shack scanner, such as the PRO-46).
I'll describe them first and then how to take advantage of one of them to get
the restricted frequencies.

There are three data test modes. These modes completely destroy any frequencies
you had programmed into your scanner, so it's best to use these techniques
before you program your scanner. If you have already programmed it, you'll have
to decide if these new capabilities are worth reprogramming.

Test mode 0. Clear the scanner.
A well-known method of clearing the scanner to all zeros is to hold down the 2
key, the 9 key, and turn on the scanner. All frequencies will be lost.

TEST MODE 1. Fill channels 1-25 with test frequencies.

Press the 2 key, the 9 key, the L/Out key, and turn on the scanner.

This fills channels 1-25 with these frequencies:

 1       30.050
 2       40.840
 3       49.900
 4      138.150
 5      162.400
 6      173.225
 7      406.875
 8      453.250
 9      511.9125
 10     108.500
 11     118.800
 12     127.175
 13     135.500
 14      66.450*
 15      76.825*
 16      87.425*
 17     157.800
 18     482.3625
 19      29.000
 20      54.000
 21     806.000
 22     857.200
 23     888.96*
 24     911.500
 25     954.9125

* indicates not within the PRO-51's normal coverage. More on how to use these
in a minute.

TEST MODE 2. Fill channels 1-17 with test frequencies.

Press 2, 9, Manual

Fills channels 1-17 with these frequencies:

30.00, 40.00, 50.00, 140.00, 155.00, 170.00, 410.00, 460.00, 510.00, 54.00,
109.00, 118.00, 127.00, 135.00, 810.00, 860.00, 950.00.

There is also a display diagnostic mode.

Display Test Mode.

Press 2, 9, Band or 2, 9, Moni.

This put the display in test mode. Every annunciator and every digit element is
turned on in a scan from the left side of the display to the right. To keep
this test mode continuous, release the buttons before the first scan finishes.
This mode does not affect stored memory. Press any key to exit this display
mode.

Now, if you've decided to try test mode 1, you will find several out-of-band
frequencies stored in your memory channels. Channels 14-16 hold frequencies in
the blocked out 66-88 Mhz range, and channel 23 holds a frequency in the
blocked out cellular base range. Once you have these frequencies stored in a
memory channel, the PRO-51's direct search feature will let you search though
these ranges. In the cellular band, the scanner searches in the correct 30 Khz
steps.
