[SCAN Y/N]:Enables top panel Scan mode on/off key.
**Once Scan is enabled, the following parameters should be checked.
[PRIORITY SCAN]: When enabled, the radio will check the priority channel as it
is scanning (every other channel), and while receiving on a non-priority chan-
nel (see Lookback A & B times below). There are two choices on how the pri-
ority channel is set:
          1-[FIXED]: Selects a fixed priority channel (cannot be changed by 
                    the user). This is set in the [CHANNEL NUMBER] block.
          2-[SELECTED]: Priority channel is the last selected channel before 
                       scan was intiated (i.e., a "user-selectable" priority).
[QT/DQT IN PRIORITY]: Disables the programmed QT/DQT decode tone during scan.
This allows a slightly faster scan rate, but the priority channel will now be
carrier squelched during scan.
[SCAN RESUME TIME]: Scan resume time interval from the end of a received call
to the time scan automatically resumes(0.5-3.0 sec. @ 0.5 sec.steps;def; 2sec.)
[LOOKBACK TIMES]: The Priority channel checking intervals while receiving on a
non-priority channel.
 {Lookback A}: Pri. ch.- no carrier present. Set short interval so as not to
 miss a call. (0.5-3.0 sec. @ 0.5 sec.steps; default:0.5sec.)
 {Lookback B}: Pri. ch.is busy, but tone squelched. Set longer than Lookback A
 since the it is busy with different tone(0.5-3.0 @ 0.5 steps; def: 2sec.)
