Use this
PIC
to analyze the 880 SRA number.
Notes:
1.
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 than 10 minutes with the top cover off.
2. When you set the power switch on the system unit to Off, wait
30 seconds before setting the power switch to On.
Step 1
Be sure that the system unit external power cable is plugged into
both the system unit and the outlet and that the outlet has the
correct voltage. If needed, see Section 5.
