Canon EOS 5 - Manual (Page 127)

■ 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 32T/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 with a
new one.
