Cleaning the Objective Lens
• Do not wipe or rub the objective lens if there is dirt or dust on it. Doing so could scratch the
surface of the lens.
• Do not wipe the objective lens with disinfectant ethanol, eyeglass cleaner, or silicone-coated
paper. Doing so could corrode the surface of the lens or leave streaks.
For information about lens cleaning paper, lens cleaner, and blowers, contact your sales
representative or local Canon dealer.
If the objective lens is dirty, clean it according to the procedure below.
1
Check for any dirt.
Illuminate the objective lens with a penlight to check for dirt.
2
Blow away any dust or dirt.
Use a blower to blow away any dust or dirt on the lens. Do not
use a brush to dust off.
Do not allow the blower to touch the objective lens.
