exposure
information.
After
about
five
years, the display may become difficult to
read. If this occurs, have it replaced at an
authorized Canon service facility. Replace-
ment is at the owner's expense.
Liquid crystal may also respond relatively
slowly in temperatures below 32°F/0°C. It
may also darken in temperatures around
140°F/60°C. The LCD panel will return
when the temperature returns to normal.
