CAMERA CARE
E Cleaning
Keep your camera in top condition by following
these suggestions for periodic cleaning. See the
precautions on page 7 for other important infor-
mation.
. Cleaning the lens surface—
Blow off dust with a blower brush and gently
wipe the lens surface with a piece of lens
cleaning paper moistened with lens cleaner.
Clean in a spiral motion from the center out-
wards.
. Cleaning mirror and focusing screen—
Use a blower brush reserved for this pur-
pose only. If more cleaning is necessary do
not attempt to do it yourself. Take the camera
to an authorized Canon service facility.
3. Cleaning the film chamber—
Use a blower brush to remove accumulated
film dust particles that might scratch the film.
Be careful not to touch the shutter curtain.
4. Cleaning the film pressure plate and film guide
rails—
Lightly wipe the surface with a piece of lens
cleaning paper moistened with lens cleaning
fluid. Be careful not to touch the shutter curtain.
Use of aerosol spray dust removers is not rec-
ommended.

E Liquid Crystal Display/Battery Notes
1) LCD Information
The LCD panel uses liquid crystal to show expo-
sure information. After about five years, the dis-
play may become difficult to read. If this occurs,
have it replaced at an authorized Canon service
facility. Replacement is at the owner's expense.
Liquid crystal may also respond relatively slowly
in temperatures below 32°F/0°C. It may also dar-
ken in temperatures of around 140°F/60°C. The
LCD panel will return when the temperature re-
turns to normal.
2) Blinking Empty Battery Indicator
There are two situations in which the blinking
empty battery indicator will appear in the LCD
panel: (1) when the battery is nearly exhausted or
(2) when the camera's self-test process detects
an internal malfunction. If the blinking empty bat-
tery indicator appears,
perform the following
operations:
1. Remove the battery, wipe the battery terminals
and reload it. Check the battery again. If the
blinking still appears, replace the battery witha
new one.
