Push the alarm enable/disable button to enable or disable the alarm. If the
green alarm LED is lit the alarm is enabled. If the green alarm LED is not lit,
the alarm is disabled.
The surge counter displays the number of transient voltage surges since
the counter was last reset. The counter is battery powered to retain
memory in the event of a power loss to the diagnostic display panel.
To reset the surge counter remove all power and press the small switch
located inside the unit on the underside of the diagnostic circuit board
(near the communication connectors). This will reset the counter to zero.
