DSC calls.

Shadow watch scan
The USA radio models use shadow watch mode
to scan for incoming DSC signals on CH70 in
any channel bank (USA, CAN, INT).
Shadow watch mode means that the scanning
operation is not shown on the LCD screen
unless a DSC signal on CH70 is detected.
To unlock a locked out channel, press <ESC

The X disappears to show it is now unlocked.
If a signal is received, scanning stops at that
channel and BUSY appears on the LCD screen.
Scanning starts again four seconds after the
BUSY annunciator disappears.
To stop at the current channel and cancel the
SCAN mode, press SCAN again or <ESC.
