Mercury Battery Loading and Checking

The built-in exposure meter of the Canon F-1 functions
only when the mercury battery is properly loaded.

Insert a coin into the groove of the battery
compartment cover and turn it to the left to remove

the cover.

Insert the battery into the compartment with negative
pole first.

Replace the compartment cover and turn to the right to
tighten.

Before inserting the battery, wipe off fingerprints or

stains on the battery poles with a dry cloth. Unclean
poles may cause corrosion and damage the camera.

A 1.35V H-D mercury battery should be used — a

Mallory PX-625 or Eveready EPX-625 is recommended.
Do not use 1.4V mercury batteries.

Be sure to insert the battery in the correct direction.

Otherwise, the meter will not function properly and the
cover cannot be screwed-in.

If the camera will not be used for an extended length of

time, the battery should be taken out of the battery
compartment to prevent possible damage to the termi-
nals from battery corrosion.
