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 your nearest Pentax service center.
