The monitor on this page is giving a signal that
a continuing error has been detected during a
self test. When a continuing error is detected,
monitoring i s stopped until t h e error i s
resolved,
the error code is flashed on the LCD bar
graph and stored in memory,
the Bypass LED comes on and the OK LED
flashes at 5 Hz.
If the error goes away, monitoring is resumed
and the OK LEDs flash at 5 Hz. T h e error
code, however, remains stored in the monitor
and may be read by using the user-invoked self
test.
