10.3.1 For cleaning the outer surfaces of the lenses and eyepieces,
wipe them with a clean cloth included in the single set of spare parts, by
first blowing off grains of sand and dust from the surfaces.
In case of severe contamination of the optical parts, do their
cleaning as follows:
– Obtain a Q-tip (used for ears cleaning). If not available, wind
a small amount of cotton wool around the end of a wooden stick, after
having sharpened the stick end
– Moisten the cotton wool (or Q-tip) with alcohol or ether, or their
mixture and then shake the stick to remove excess of liquid;
– Wipe the glass with the cotton wool (or Q-tip) several times
without touching the eyepieces with hands
– Replace the cotton wool (or Q-tip) with a dry one and perform
circular strokes with the cotton wool moving it from the center to the edge to
finish the cleaning.
It should be remembered that the unit should be de-energized
during the process of optical surfaces cleaning. Perform cleaning of the
monocular pair, fixing assembly and unit accessories to remove dust, dirt,
etc. (if any).
