Part 3: Adjustment
Memory IC handling
Memor y IC (IC808) on the main board stores the data for the ser vice
adjustments, and should not be replaced except for the case of defective device.
The data of lamp replacement monitor timer is stored in the IC808.
Please note that the lamp replacement monitor timer is reset when the memory
IC (IC808) is replaced. (Lamp replacement monitor time can not be set to the
previous value.)
Caution to memory IC (IC808) replacement
When IC808 is replaced with new one, the CPU writes down the default data of
the service adjustments to the replaced IC. As these data are not the same
data as factor y shipped data, it should be required to perform the re-
adjustments following to the "Electrical Adjustments".
Please note that the lamp replacement monitor timer is reset.
Caution of Main Board replacement (in the case IC808 is not defective)
When the main board is replaced, IC808 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".
In this case, the lamp replacement monitor timer can be kept the value as before.
