4 Other Functions and Options
Wiper operation varies according to the mounted
accessories. Refer to the operation manual of the accessory
to use.
* (NOTE)
• Do not operate the wiper with dust, oil, foreign obstacles stained
on the glass surface. Otherwise, the glass may be damaged.
Completely clean the glass before operation.
• If the wiper is operated in the low-temperature environment or for
wiping snow, condensation may form on the glass.
• Do not operate the wiper in a dry condition without moisture.
Otherwise, rubber blade deterioration or incomplete wiping may
result.
• Replace the rubber blade when worn, deformed, or damaged, or
when incomplete wiping occurred. Contact your Canon dealer.
• To use the wiper manually, set the power switch of the wiper to
“OFF”.
Do not manually use the wiper while it is turned “ON”.
4-5 Nitrogen Gas Filling
(Option)
To prevent fog or condensation on the internal surface of the
lens, you can fill the lens barrel with nitrogen gas.
Nitrogen gas should be refilled at the periodic overhaul, and
before the critical event.
* (NOTE)
To refill nitrogen gas, gas canister and filling tool are required.
Contact your Canon dealer or your Canon sales representative.
