MANUAL

10.3.1For 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).
