MAINTENANCE
The Pentax.645 is a precision instrument. Please
read the following instructions concerning
handiling/maintenance.
• Do not drop or strike the camera against solid
objects. In the event the camera may have
sustained a heavy blow or shock, it is
recommended that it be taken to an authorized
Pentax service facility for inspection and possible
repair.
• Should the camera become drenched either by
rain or water, wipe off with a soft dry cloth as
soon as possible.
When used at the beach or
while boating, wipe off the exposed sections as
soon as possible; salt air/moisture damage may
occur if left unattended for long.
• Do not leave or store the camera in a hot and
humid location; for example, the temperature of
an automobile interior during the summer tends
to rise rapidly. Gaseous release from insecticides
such as naphthaline may also prove harmful to
the camera. Camera should be stored
In
a cool,
well-ventilated area
if
at all possible.
• The temperature range at which your camera will
continue to function properly extends from 50°C
to "20°C. Extremely low temperature reduces
the efficiency of the batteries. Therefore, the
camera should be protected against low
66
temperature conditions. Sudden changes of
temperature will often cause condensation of
moisture within or on the exterior of the camera.
Do not subject the camera without proper
insulated protection to sudden temperature
changes; out into the cold outdoors from a warm
room, or vice versa. It is suggested that the
camera be placed in a vinyl bag; allow a wait of
approx. 30 minutes for each 10®C change of
temperature, before removing the camera.
•To remove dust on the lens and viewfinder glass,
use a blower, followed by the application of a
lens cleaning brush. Smudges such as finger
prints should be carefully wiped with a clean, soft
cloth moistened with a few drops of a lens
cleaning solution available on the market. Wipe
the lens surface gently out from the center
toward the edges in a spiral.
• Never attempt to touch the reflex mirror and
focusing screen, lens, etc., with the fingers; they
can be scratched very easily.
• Do not touch or handle the shutter curtains with
the fingers.
• Once immersed into water, the camera will be
rendered inoperable. In such a case, contact
vour nearest Pentax service center.
