Camera Cleaning

·Do not apply any solvent such as thinners and/or alcohol to clean the external parts of the camera.

·To wipe dirt or fingerprints from the camera surface, apply a soft cloth or silicone-treated cloth after blowing dust off the camera.

·Do not apply silicone-treated cloth to glass portions such as viewfinder windows or eye- piece lenses. Such chemically treated cloths may damage the optical coatings of the glass. Blow the dust off the glass surfaces and wipe dirt off the glass with lens cleaning tissues or well washed micro fiber cloth, using a lens cleaning liquid available at camera stores.

LCD (Liquid Crystal Display)

·The LCD may occasionally flicker or flare under bright ambient light. Such phenomena are not malfunctions, but typical attributes to LCD devices.

·The LCD may darken in an extremely high atmospheric temperature over 60° C or 140° F. The LCD appearance will return to normal when cooled to room temperature.

·The display speed of LCD may slow down in a low atmospheric temperature. This is not a malfunction, but rather an inherent characteristic of LCD technology.

Operational Conditions of Camera

·Temperature range: -5deg. C to +40deg. C or 23deg. F to 104deg. F. Relative humidity range: Less than 80%. If left in the direct sunlight or on the dashboard of a car, the camera may far exceed operational temperature range, causing damage to the camera. Do not leave your camera in conditions of heat or direct sunlight. If accidentally overheated, place your cam- era in a cool place until it returns to a normal room temperature before further use.

Storage and Maintenance

·Your camera is a precision instrument. It is strongly recommended that you visit a service center or a repair station for routine checks every one to two years and for overhauls every three to five years. The best service will be provided at Bronica/Tamron service centers.

·Store the camera in a dry, dust free, cool place. Put caps on the camera and lens openings, cavities, accessory mounting devices or electric terminals before storing your camera and lenses.

·Do not store your photographic equipment in cabinets or drawers containing insecticides, disinfectant, adhesives or other chemical substances. Chemical fumes are extremely harm- ful to precision mechanisms, electronic devices, optical elements of cameras and photo- graphic films.
