Installing the Battery
The Mamiya M645 uses one 6v silver
oxide (4SR44) or one 6v alkaline bat-
tery (4LR44).
1. Pull the Battery Chamber Latch (26)
slightly toward the lens and the Chamber
Cover will open.
2. Insert the battery into the chamber making
sure that the polarity of the battery matches
the diagram in the chamber.
3. Make sure that the Battery Removal
Ribbon (A)
passes under and over the battery.
CAUTION:
1. Carefully wipe the battery's contacts with a clean, dry cloth
before inserting the battery into the camera.
2. If the camera will not be used for a while, remove the battery
from the camera.
3. Properly dispose of used batteries.
4. An unused battery may loose some of its charge, even if the
battery is stored in a cool, dry place. Consequently, check the
condition of a battery after installing it into the camera by using
the Battery Check Button.
