Battery testing
The CdS light meter is powered by a
1.35 volt mercury-oxide cell, the Mallory
\
PX
625,
or equ
ivalent,
such as the Varta
Pertri
x
7002. These cells offer a normal
service life of one to two years.
To test the
battery,
hold the camera
horizontally,
look through the
viewfin-
der,
and pull the field-of-view preselec-
tor
lever
(19) outward
,
away from the
lens. If the battery is still
serviceable,
the meter needle will fall within the cut-
out area at the lower
ri
ght-hand side of
the readout
bar.
Battery changing
The battery compartment
cover
is coin-
slotted to permit easy removal. When
inserting a new cell
,
always be sure that
the written side faces upward before
repla cing the
cover
plate.
