Batteries Care
1. Battery life of the originally supplied batteries is dependant on storage conditions.
2. Blots and fingerprints on terminals may cause loose connection and corrosion. Wipe
them off before loading the batteries.
3. It is advised to carry spare batteries in remote or foreign locations.
4. Battery performance decreases in low temperatures. Keep them warm when in cold
climates or locations.
External battery case PE401 is available as an optional accessory.
5. Store the batteries in a cool and dry place, away from direct sunlight.
6. Remove the batteries from the camera body when they will not be used for a long
time.
7. Replace the batteries with new ones as soon as they are exhausted. Liquid leakage
from the battery may damage the camera.
8. Read the label warnings of the batteries for their handling.
Battery Power / Battery Care

charge display
Battery power The camera’s power is turned on when the drive
dial is set to “S,” “C” or “M.UP.” In order to prevent
the camera’s batteries from discharging, sleep
mode is automatically established if no operations
are performed for a specific period of time while the
power is ON (with exposure metering status
maintained).
The initial setting for the exposure metering
status maintenance period is 15 seconds. It can be
changed at any time to a period within a 5- to 60-
second range using the custom settings. (C-04 on
page 93)
In sleep mode, operating the shutter button or function setting button restores power
ON status.
In sleep mode, the shutter speed and f-number among the external LCDs go off, and
the marks shown in the figure are displayed. (These marks appear in program AE
mode.)
For the purpose of the descriptions and explanations provided in these
instructions, it is assumed that the camera’s power is on.

Insert the battery according to the polarity indica-
tion in the battery compartment, and close the
battery cover.
Battery used: Sony CR2032 or equivalent

polarity
The button battery supplies power to the magazine's LCD when the film magazine is
detached from the camera.
1. Remove the battery compartment
screw cap.
Use a coin or suitable screw driver and turn it
counter clockwise.
When the magazine is installed onto the body, the power will be supplied to the maga-
zine from the camera body.
You can take shots without installing the battery into the magazine. However, if you
remove the magazine from the body, the magazine does not indicate film sensitivity
or number of shots.
The magazine does not have a battery level indicator. When the magazine LCD panel
becomes dark or disappears, replace the battery. As a rough guideline, the battery
should last approx. one year.
