Cleaning the Screen
To clean smudges from the screen, use a soft cloth and a non-
abrasive, non-hydrocarbon cleaner. Use a good quality optical cleaning
solution and lint-free paper wipes.
Cleaning the Mirrors
The WN-5220-S’s optical mirrors can become dusty in normal
operation, particularly if the operating environment is dusty. When the
WN-5220-S is serviced, these mirrors may also accumulate accidental
smudges and fingerprints. Dust and smudges on the mirrors can
seriously degrade the WN-5220-S’s performance, so these should be
removed as soon as possible.
Because the mirrors are front surface mirrors and the lens is coated,
use care when attempting to clean them. They are easily scratched if
improperly cleaned. Use an inert dry dusting gas or dry, filtered
compressed air to remove dust from the mirrors. To remove smudges,
use an optical quality liquid cleaner and a disposable commercial lens
tissue. If the liquid is not a spray, apply it to the tissue first.
