Inspection
In order for your PC to continue operating at optimum condition, periodic in-
spections are necessary. The main components of the PC are semiconduc-
tors and have a long service life, but, depending on the operating environ-
ment, there may be more or less deterioration of these and other parts. A
standard inspection schedule would be once every six months to one year,
but more frequent inspections may be advisable depending on the operating
environment. Try to maintain the inspection schedule once it has been set.
Check to be sure that the power supply, ambient temperature, humidity, and
so on, are within the specifications (see
Appendix B
). Be sure that there are
no loose screws in any of the Units and that all battery and cable connections
are secure. Clean any dust or dirt that has accumulated. Check all fuses, re-
lays, and other replaceable parts.
