• Watch the Ready light carefully. As each
system is tested, the light emits either a short
(1/4 second) or a long (3/4 second) flash to
indicate whether the system has passed or
failed. A short flash means that the system
being tested has passed; a long flash means
that it has failed.
Table 6.1 on the next page lists the confi-
dence tests in the order in which they occur.
If you see a long flash, use the table to
determine which system failed the test, then
call an authorized service representative.
For example, if the fifth test yields a long
flash, the keyboard has failed the confidence
test.
