2. Measure to establish uniformity of the high voltage PWB to improve
productivity.
1.Model Name:
AR280/285/335
2.General:
A change has been carried out in the high voltage PWB used in the models listed above.
The new high voltage PWB is the same one which is used in model AR405.
This action has been carried out as a measure to establish uniformity of the models listed
above with model AR405. It is important to note that both the old parts and the new parts
can be used in the models listed above.
3.Action:
From the 1st lot of February 1999 production.
3. Parts change carried out in accordance with a change to in-house production
