CLEANING
When the external cover, monitor, etc. are stained, wipe with a dry cloth.
If the external cover is badly stained, prepare a tepid solution of neutral kitchen detergent.
Moisten the cloth with the aforementioned solution and wring it thoroughly. Then, wipe the
external cover with it.
Cleaning parts which contact the patient
If the forehead rest, face shield and operation switches are stained, prepare a tepid solution of
neutral kitchen detergent. Moisten a cloth with the aforementioned solution and wring it thor-
oughly. Then, wipe these parts with the cloth.
Cleaning the lens
If the lens is stained, wipe it with the accessory silicone cloth. If the stain is not removed,
moisten a worn-out cotton cloth a little with a mixed solution (the ratio of ether 4 to alcohol 1)
and wipe the lens with it.

volatile solvent. To prevent the resin parts from discoloring or deterio-
rating, do not use benzine, thinner, ether or gasoline.
