3.2.1 Hardware Control Buttons
To the right of the touchscreen, there are 6 pairs of
hardware control buttons which are part of the front
panel overlay. Located to the left of the buttons are
Status LED’s which are green under normal, no
fault conditions. The hardware buttons provide
immediate control of 6 main transmitter functions:
a. Power Control - Auto/Manual
b. Remote - Enable/Disable
c. Power - Raise/Lower
d. Exciter - A/B
e. Drive - A/B
f. Transmitter - On/Off
The Status LED’s light amber (yellow) for a warning and red for a fault condition in the
transmitter subsystems. LED’s light green if the sub-system is normal. This provides
quick sub-system status information without having to be familiar with a menu
structure.
