Before repairing, check the type of the battery used in
the camera and its volcage. Confirm that the battery is
silver oxide type having 1.56 V. (1.58 V under normal condition.)
A mercury battery (1.3V) or different ctype of battery causes
inaccuracy of the meter reading or immovability of the meter needle.
The meter needle will not move when a battery is puc in a battery
compartment up side down.
The meter reading will noc be accurate if the winding lever is
pressed at full aperture metering.
The meter reading will not be accurate if the winding lever is
not fully pressed at stopped down metering.
Estimate intentional over or underexposure by 0.5 or 1 step by
the eye in the view finder roughly as shown in figure.
