Olympus OM-PC, Instruction Manual

Page: 71 / 78

A: (1) When new batteries are inserted into the
camera, (2) when you are using the camera after
it hasn't been used for a long time, (3) when
you think the batteries may be worn out, and
(4) when the temperature is extremely low.
(If the battery voltage is low, the shutter may
not fire when using the self-timer; even if the
batteries check out OK.)
Q: What type of batteries should I buy?
A: Buy two SR44 silver-oxide batteries or LR44
alkaline batteries. Do not use HR44 mercury
batteries or two different types of batteries of
the same size, or mix an old battery with a new
battery.
Always replace both batteries at the same time.
Q: How long do the batteries last?
A: Generally, SR44 batteries will last about one
year and LR44 batteries about six months.
Q: The batteries seem to have been worn out while
I was shooting in cold weather. What can I
then do to take pictures?
A: Bring them to room temperature by keeping
the camera inside your coat close to your body.
They may recover and allow you to resume
shooting. Never heat batteries with an electrical
appliance or other device.
Q: I took my picture at an intermediate point be-
tween two aperture numbers.
A: No problem. Your picture is correctly exposed.
Q: In the manual mode, I took my picture at an
intermediate shutter speed.
A: Intermediate shutter speeds cannot be used. If
you have set the shutter speed dial at an inter-
mediate position, the shutter will fire at either
of its neighboring shutter speeds.
Q: I want to take macro pictures with flash in the
programmed mode. Is it possible?
A: The programmed mode tends to give a larger
aperture, causing the picture to turn out over-
exposed or not have enough depth of field. It is
recommended, therefore, to use the aperture-
preferred "OTF" auto flash mode for macro
shots.
Q: In the program mode, "1000" and
blink even with the lens set at its minimum
aperture.
A: This indicates overexposure with a lens having
less than five aperture stops. In this case, use an
ND filter suited or a slower film.
Q: In the program mode, it seems that the
shutter speed displayed in the viewfinder differs
from the actual shutter speed.
