Zhumell Rangefinder RF645 - Manual (Page 32)

Film Wind Lock Release
If battery power drops below the camera's operational level, or the
main switch is mistakenly turned off during a long exposure shot (B
or longer than 1 second exposure), the film wind lock mechanism will
interrupt the camera operation and prevent the film from being
advanced any further. To release the film advance lock, press the lock
release with a pointed object such as a ballpoint pen. The film wind
lock will be released and the film can then be advanced.
Note 1: When the battery power becomes depleted, replace with
fresh ones as soon as possible.
Note 2: Do not press the film advance lock release for any reason
other than outlined above.
8. Preliminary Checklist (Before loading film)
9. Ensuring years of enjoyment through proper care and handling
Before Shooting
· This camera will not operate without batteries. Load batteries correctly and check the bat-
tery capacity before use.
· Make sure the camera is in good working order before taking it out for shooting. Before
shooting important events or subjects, it is especially wise to ensure all camera functions
are in good photographing condition by taking test shots on film.
· When carrying the camera by the strap, fastening it on a tripod or fitting it on a bracket of
a large flash unit, be sure the strap ring, tripod socket or mounting lock are the correct size,
that they are in good working condition, and that the camera is securely fastened to these
devices.
About the Batteries
· Batteries left in a camera for prolonged periods may leak, resulting in malfunctioning of
the circuitry or corrosion of internal mechanisms. When the camera is not used for an
extended period, remove the batteries prior to stowing.
· In the event that a battery leak or corrosion is discovered, no matter how seemingly minor;
have a detailed examination performed at a camera service center without delay.
· Stains, dirt or fingerprints on the battery contact may cause malfunctioning or corrosion of
the circuitry. Wipe both contacts of the battery chamber and the ends of the batteries clean
with a soft cloth or paper before loading the batteries to make sure contacts are all clean.
· Do not forget to carry backup batteries when setting out for a long photography trip or
shooting in a cold place.
· Battery power lessens proportionally with the low surrounding temperature. Carry a set of
backup batteries in a warm pocket or container when shooting in a cold place and alternate
use of different sets of batteries.
· If the battery-warning symbol appears on the LCD in the viewfinder, replace the batteries
with a fresh set as soon as possible.
