6.3.1 Objective Lens

Note: Do not wipe off or rub the objective lens when there is dust or other substances on it.
This could scratch the lens surface.
Note: Never wipe the objective lens with disinfecting ethanol, eyeglass lens cleaner, or cleaning
paper containing silicon.
The lens surface could be damaged or the surface may not be completely wiped off.
Note: Do not let the tip of a blower touch the objective lens.
Use the procedure below to clean the objective lens when it is dirty.
Please order the lens cleaning paper, lens cleaner, and blower from a Canon representative or distributor.
1 Check for any dust or dirt.
Shine the light of a pen light, for example, onto the objective lens, and check how much dirt is
present.
2
Wipe off any dust or dirt.
Remove the brush from the blower brush, and use the
blower to blow away any dust or dirt on the objective
lens.
3
Wipe off the objective lens.
Gently wipe the lens with Canon-designated lens
cleaning paper that has been wet with the Canon-
designated lens cleaner.
Starting from the center of the lens, wipe the lens in
increasingly larger spirals toward the circumference.
Change the paper, and wipe several times until the dirt
is removed and the cleaner is completely wiped off.
