３ Blow away the dust and garbage of a objective lens by Blower
４ When not becoming beautiful by Blower, use clean gauze or a cleaning paper including some
anhydrous ethyl alcohol and Mixed- solution of ether.
Please wipe lightly to draw a circle little by little outside from a center with clean gauze or
cleaning paper containing the mixed-solution.
５ If cleaning of an object lens is completed,
IR filter knob is pushed in and a observation light intensity control knob is returned to the
position at 10:00 of a clock.
A point after having finished wiping it
※Throw away the cleaning paper (gauze) used once. By wiping with the mixed-solution using a
new cleaning paper (gauze) again, it can wipe more finely.
※If it wipes while garbage had been attached, or it wipes strongly, a crack may go into an object
lens.
※Please do not use the chamois leather and silicone crossing.
※Please warn safekeeping, the handling enough mixture liquid evaporates and because it is easy
to catch fire.
※When there is the dirt which I do not get with mixture liquid, it may be able to take, if a swab is
absorbed with little water and it wipes lightly. After this work、please wipe a lens with The
above-mentioned mixed-solution finely.
Please contact our company or an agency of a buying request when there is the terrible dirt
which you do not get even if you wipe it.
