Olympus OM77AF Instructions Manual page 73

Q: Why doesn't the flash fire?
A: There are two possible reasons. (1) Flash firing
is automatically inhibited at shutter speeds
faster than 1/100 sec. (when using T-series
flashes and the Power Flash Grip 300). (2) Are
you trying to fire before the unit has been
recharged?
Q: When should I check the batteries?
A: (1) When new batteries are inserted. (2) After
the camera has not been used for a long time.
(3) Before beginning a prolonged period of use.
(4) When it is very cold.
Q: In the finished print, a peripheral portion of the
picture is cut, though I framed it inside the
viewfinder.
A: In some color prints and color slides, a periph-
eral portion of the picture may be eliminated in
the laboratory. It is recommended, therefore,
to leave some margin in composing your picture.
Q: How do I clean the lens?
A: Use a soft, clean, cotton cloth (preferably a
washed one) and a small quantity of pure
alcohol. Slowly wipe the lens with a spiral
motion, from the center outward.
Q: How do I clean the camera?
A: Dust, moisture, and salty air are harmful to
cameras and lenses. Wipe the camera surfaces
clean and let dry after using it in rain or mist.
When used near the sea, wipe it off with a
cloth moistened with clean water, then clean
and store it.
Q: Why are there sometimes scratches on the
film?
A: The cause may be a soiled film passage. The
film compartment may be soiled by film debris
during long use of the camera. Be sure to dust
off the camera periodically.
Q: How can I preserve the camera in a humid
environment, and
mildew on it?
A: Take it out of the case and store it in a poly-
ethylene bag, together with a dessicant such as
silica gel. However, do not use a dessicant that
includes insecticide.
