How to insert the battery
• As the shutter is electronic, it will not
operate without a battery.
•
If the shutter is operated without a
battery the safety device will activate
and the mirror will stop partway up.
Inserting the battery
1) Lift up the crank at the bottom of the
camera case and turn
it in a coun-
terclockwise direction.
2) Take out the battery case and replace
the battery.
3) Re-insert the battery case making sure
that the (+) (red) and (-) (blue) marks
6
correspond. If this is done incorrectly,
the safety mechanism will activate
when the shutter is released.
To secure the battery case, press down
and turn the crank in the direction
of the
arrow until
it aligns with the red dot.
The alkaline battery should last about 6
months, while the silver-oxide about one
year with average
use at normal tempera-
tures. When the
TIL Pentaprism is used ,
the battery will last
less as it also must
activate the meter.
The battery supplied with your camera
may be
~lightly below full capacity as
it is considered to have discharged
spontaneously.
Also,
be sure to remove the battery when
the camera
is not in use for an extended
period
of time, as the battery may
deteriorate and cause damage
to the
contact points.

Battery Check
1) Press the battery check button at the
back
of the camera.
2) If the red shutter speed indication
lamp does
not light up, there is no
battery in the case, the battery is
drained, or the battery contact is
loose.
3) When inserting film or before taking a
picture, check the battery.
When the
battery power becomes insufficient the
mirror will stop partway up, blocking
the viewfinder. This safety device has
Battery check
been incorporated to prevent inac-
curate shutter speed.
•
To reset the mirror, press the safety
device release
button with a sharp
object, and press the shutter button
for
one blank exposure. The mirror will
then return
to the original position.
• Insert the battery when the
mirror
is back in the normal position, not when
it is partway up, as it consumes the
battery.
