Flat P
anel Display Cleaning
The display is a soft plastic display and must be treated with care during cleaning.
CAUTION. Improper cleaning agents or m ethods can damage the flat panel
display.
Avoid using abrasive cleaners or commercial glass cleaners to clean the display
surface.
Avoid spraying liquids directly on the display surface. Avoid scrubbing the
display with excessive force.
Clean the flat panel display surface by gently rubbing the display with a
clean-room wipe (such as Wypall Medium Duty Wipes, #05701, available from
Kimberly-Clark Corporation).
If the display is very dirty, moisten the wipe with distilled water or a 75%
isopropyl alcohol solution and gently rub the display surface. Avoid using excess
force or you may damage the plastic display surface.
CAUTION. To prevent getting moisture inside the instrument during external
cleaning, use only enough liquid to dampen the cloth or applicator.
