Description
This LED is red and lights for a major alarm condition. Major
alarms occur for hardware or software conditions that
indicate a serious disruption of service or the malfunctioning
or failure of important circuits. The LED goes off when all
major alarms have cleared.
This LED is yellow and lights for a minor alarm condition.
Minor alarms indicate a less critical error condition. The
modulator may continue to operate with some loss of
functionality. The LED goes off when all minor alarms have
cleared.
This LED is yellow and lights when any one of the RF
carriers is set to continuous wave (CW) mode.
This screen displays status and operating screens controlled
by the front panel keys.
The Down Arrow key decrements a displayed value or
navigates through a set of displayed values. This key is only
active when the display has a flashing value, which indicates
that the value can be changed. This key is primarily used for
decreasing a displayed value such as frequency or level.
The Up Arrow key increments a displayed value or navigates
through a set of values. This key is only active when the
display has a flashing value, which indicates that the value
can be changed. This key is primarily used for incrementing a
displayed value such as frequency or level.
