Canon FT QL - Mercury Battery Loading and Checking

Mercury Battery Loading and Checking
The built-in exposure meter of the Canon FT functions
only when the mercury battery is properly loaded.
1 Press thumb against the battery compartment cover
and turn to the left to remove.
2 Face the central contact of the mercury battery in¬
wards and insert.
2 Replace the cover by turning it to the right.
■ Before inserting, wipe all battery poles clean of finger¬
prints or stains with a dry cloth. Unclean poles may
cause corrosion and damage the contact points of the
camera.
■ A 1.3v M20 (#625) mercury battery should be used—
equivalent to Mallory RM-625R, Eveready E625N,
Burgess Hg-625R.
■ Be sure the battery Is inserted in the correct direction
by referring to the diagram on the compartment cover.
Otherwise, the meter will not function properly and the
cover cannot be screwed in.
■ When the camera is not to be used for a long period,
remove the mercury battery and keep in a dry place.
