Precautions
Releasing the shutter with no film in the camera
The film transport mechanism has a built-in safety lock
that prevents the shutter from being released after the
last exposure on a roll of film, or when there is no film
in the camera. When the Shutter Release Button locks
under these conditions, do not force it. To release the
shutter, set the Multiple Exposure Lever to "MULTI",
and the shutter will release.
Mirror Lock-up
When the mirror is locked in the up position and the
camera is outdoors in sunlight, there is a small
possibility that sunlight can enter the lens, focusing on
the rubberized cloth focal plane shutter and burning it.
Therefore, when the mirror is in the locked-up position
and you are photographing outdoors in sunlight, return
the mirror to its down position as soon as you are fin-
ished with mirror lock-up photography.
The position on the Shutter Speed Dial
If the shutter is released with the this setting on
the Shutter Speed Dial and the PD Prism Finder
is not attached to the camera, the mirror will lock up
and the Film Advance Knob will not move. If the
camera is left in this condition, the battery will loose
power within a couple of hours.
Photographing at low temperatures
When photographing at low temperatures, please
note the following points to assure camera per-
formance:
1. Use a fresh battery.
2. When using electronic flash, set the Shutter
Speed Dial to 1/30 sec. or slower.
3. Place the camera in the outside are only at
the moment of exposure.
When working in extremely low temperatures, it
may be impossible to wind the Film Advance Crank
after the shutter is released. If this occurs, place
the camera in a warm place, and then firmly press
the upper Shutter Release Button as far as it goes.
A battery that malfunctions in very low temperatures,
will become usable when it is exposed to normal
temperatures. The battery should not be exposed
to rapid and extreme changes in temperatures.
