vice 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 IC1841.

when the memory IC (IC1841) is replaced.

writes down the default data of the service adjust-
ments to the replaced IC, refer to the service adjust-
ment table. As these data are not the same data as
factory shipped data, it should be required to perform
the re-adjustments following to the “Electrical
Adjustments”.
Please note that in this case the lamp replace counter
will be reset.
●
Caution of Main Board replacement (in the case
IC1841 is not defective)
When the main board is replaced, IC1841 should be
replaced with the one on previous main board. After
replacement, it should be required to perform the re-
adjustments following to the “Electrical Adjustments”.
