Service Adjustment Menu Operation

ice adjustments, and should not be replaced except for
the case of defective device.
If replaced, it should be performed the re-adjustments
following to the “Electrical Adjustments”.
The data of lamp replacement monitor timer is stored
in the IC1801.

shipped data, it should be required to perform the re-
adjustments following to the “Electrical Adjustments”.
Please note that the lamp replace counter is reset.
