Canon EOS 3 - Manual (Page 7)

Handling Precautions
(11) After detaching the lens from the camera, put on the lens caps or put
down the lens with the rear end up to avoid scratching the lens
surface and electrical contacts.
(12) Even when the Main switch is set to <H>, a small amount of power
is still supplied to the camera’s LCD panel. However, this does not
affect the number of film roils which can be taken with the battery.
In time, the camera’s LCD (liquid-crystal display) panel indications may
become light and difficult to read. If this happens, have it replaced (at
cost) by a Canon Service Center.
At low temperatures, the display response of the LCD panel may become
slower. And at 60°C or higher temperatures, the display may blacken. In
either case, the display will return to normal at room temperature.

If the battery power falls to a very low level or a camera misoperation or
malfunction occurs,
“be”
will blink on the LCD panel. In such a case,
follow the procedure below:
(1 ) Press the battery check button to check the battery power. If the
battery power is low, replace the battery.
( 2 ) If the battery power is normal, remove the battery and reload it.
( 3 ) Release the shutter once.
If the
“be”
then turns off, the camera is back to normal. However, if this
procedure is repeated and
“be”
still continues to blink, the camera has a
malfunction. Take it to your nearest Canon Service Center.
