6-1-4 After Making Adjustments
After finishing all adjustments, test the monitor in
all directions. If, for example, the monitor does not
meet adjustment specifications when facing north,
reposition the monitor to face east and readjust.
This time, try for an adjustment closer to the ideal
setting within the tolerance range. Test the unit
again in all directions. If the monitor again fails to
meet specifications in every direction, contact
your Regional After Service Center for possible
CRT replacement.
