5. Replace the cover of the battery compartment.
6. Press CLR, FUN, MONTR, MONTR or just turn the power to the PC OFF
and then ON again to clear the error message on the Programming Con-
sole.
Daily and periodic inspections are required to keep PCs working in top condition.
PC are constructed out of semiconductor components, which although have an
extremely long life time, can deteriorate under improper environmental condi-
tions. Periodic inspections are thus required to ensure that the required condi-
tions are being kept.
Inspection is recommended at least once every six months to a year, but more
frequent inspections will be necessary in adverse environments.
Take immediate steps to correct the situation if any of the conditions in the follow-
ing table are not met.

• Always turn off the power supply before replacing a Unit.
• After replacing a faulty Unit, check the new Unit to make sure that the same
problem does not appear again.
• When returning a Unit for repairs, provide as many details about the problem
as possible in writing and attach it to the Unit before delivering it to your
OMRON representative. (See inside back cover for regional offices.)
• To clean bad contacts, use a clean cotton cloth soaked in industrial alcohol and
be sure to remove any threads from the cloth before mounting the Unit.
