1.3 About Commands
The transceiver supports commands to provide more advanced control and configuration
features. A command is simply a key press, or series of key presses, that cause the unit to
perform a function. This section provides an overview of the command architecture.
1.3.1 Command Levels
In order to accommodate all the commands required to provide the necessary operation,
commands have been divided up into levels (abbreviated as 'L1', 'L2' etc). This results in the most
common commands needing the fewest key presses to access.
There are five command levels in all, three of which are available to the operator (Operator
Commands). For each command level up to 10 commands are available: 1-9, and '#'. Note: for
command level 1 (L1) only, the ESC (*) button has an associated function as you cannot go a level
down. The zero (0), and the ESC (*) key are reserved to move between the command levels as
follows:
step up through command levels
step down through command levels
When stepping through command levels, the level is shown as a subscript digit in the 4
th
character
position on the lower line of the display, see figure. Note that this display position is left blank for
the default level (L1).
Figure 1-6. The Screen showing 'Level 3” in the Command Level Display Position
The Operator Command levels 2 and 3 (L2 & L3) are 'time limited', if the user gets into one of
these command levels and does not enter a command within 5 seconds, the unit automatically
returns to command level 1.
Note that after exiting a L2 or L3 command, the timer is reset to 5 seconds, so if you want to return
to level 1 immediately, you have to press level down key ('ESC' or '*'). This allows you to perform
another command on that level without having to start over from level 1.
In addition to the three command levels available to the operator, the unit can be put into a mode
that allows access to maintenance and supervisor commands. These restricted command levels
(L4 & L5) are to allow authorized personnel to set operating policy for the radio through use of
'Permissions', and perform other maintenance and configuration functions; these are explained
later in the manual.
The restricted command levels (L4 and L5) should NEVER be enabled in flight. Incorrect
use could render the unit non-functional! These levels exist for configuration and
maintenance use only.
