Step 1
Notes:
1.
If an unexpected error occurs (such as blinking 02, 30, or 99 numbers
on the two-digit display, a steady C6 displayed on the two-digit display,
the system loops, or the system hangs), then go to "Undetermined
Problem PIC 9860" on page 3-104.
2. Be sure that all programs or operating systems are stopped (get help if
needed).
3. Some system unit components do not cool correctly when the top cover
is off. For this reason do not power the system unit on longer that 10
minutes with the top cover off.
4. If the Service Request Number (SRN) provided by the customer does not
solve the problem, go to the "Problem Determination Procedure" on
page 3-22.
You should have an SRN either from information recorded on the
"Appendix B. Problem Form" from the Problem Determination Guide or
from diagnostic tests results. If needed, see "Service Request Number
Description" on page 2-17 for a description of the SRN.
DO YOU HAVE A SERVICE REQUEST NUMBER?
NO Go to "Problem Determin':ltion Procedure" on page 3-22.
