In case of the "Optics Contamin" alarm (see Table 10 on page 51) the
window has to be cleaned.
To clean the window:
1. Flush the window with water to remove coarse grains.
2. Clean the window with a lens-cleaning wipe.
CAUTION
Particles between the towel and the window may damage the anti-
reflection coating. Therefore, instead of circular rubbing, the window
should be wiped once across the window. If additional wiping is
needed, a clean part of the towel should be used.
Storage
Place caps on all external connectors if stored unpacked for extended
periods of time in an unconditioned area. Also, maintain a dust cover
on the window during long periods of storage.
