The Keyboard

MANUAL

The MANUAL button puts the scanner in Manual mode. From Manual mode,

you can examine or program individual scan channels. By repeatedly pressing the

MANUAL button, you will step through all the scan channels that contain

frequencies. Even locked frequencies will appear when you press the MANUAL

key, but if a channel has been cleared, MANUAL will skip over it.

You can switch to Manual mode at any time (while in Search mode or Scan

mode) by pressing the MANUAL button.

Down arrow

Above the SEARCH and SCAN buttons are Up arrows and there is a separate

button to the right of the MANUAL button that is labeled with a Down arrow.

These buttons are used to direct the direction of searching, scanning, and step-

ping through channels. The use of these buttons is not symmetrical, so it may be

a bit confusing when and how they are used.

The Up arrows above the SEARCH and SCAN buttons are there simply to let

you know that when you do a search or scan, they will occur in an ascending

order. You will move from the lower limit to the upper limit in a search and from

the lower channels to the higher channels in a scan.

The Down arrow, however, can be used to stop searching or scanning without

leaving the modes, and to change the direction of both searching and scanning. It

is also used to step down through a frequency range while in Manual mode.

Using the Down arrow while searching

During a search, if you press the Down arrow, the search will be halted on the

frequency it was searching at the time of the key press, but the scanner will

remain in search mode. If the frequency is active, you will hear it. You now have

two options with the Down arrow button. If you press it briefly, the scanner will

search downward by the search bank increment to the previous (that is, lower)

frequency and stop on it, whether it has activity or not. You can continue step-

ping downward through the search range in this manner. The scanner will still

skip over any frequencies that have been locked within the search bank.

If you press and hold the Down arrow button for a moment, the scanner will

begin searching through the search bank moving from the upper limit (but

starting at the frequency you were on) to the lower limit. In other words, by

pressing and holding the Down arrow, you can make the scanner search from

high to low instead of its normal search from low to high. This is not a “mode,”

however. That is, if you start searching downwards, the next time you press the
