Maintenance should be carried out at least twice a year and

> Wipe the external surfaces of metal and plastic parts free of
dust and dirt with a cotton cloth. Silicone grease can be used
for this purpose.
> Clean the contacts of the unit with a non-greasy organic
solvent.
> Check the glass surfaces of the eyepiece and the lens. If neces-
sary, remove dust and sand from the lenses (preferably using a
non-contact method). Cleaning of the external surfaces of the
optic should be done with substances designed especially for
this purpose.
