Canon EOS 1000N - Manual (Page 95)

Liquid Crystal Display/Battery
Notes
The LCD panel uses liquid crystal to show
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.
