Clearing alarms
Clearing an ATG of alarms is important because, depending on how the T5 ATG has been set up,
alarms can: disable channels, start an annunciator, or stop a line test underway. Administrator
privileges will be necessary to clear line alarms on a T5 ATG. For instructions on how to obtain an
Administrator access level, please refer to the
Fuel Management System Programming Guide T5
Series
(000-2142).
