Caring for the Camera and Battery: Cautions Camera Care ˔ Do Not Drop Do not drop the camera or lens or subject them to blows. The product may malfunction if subjected to strong shocks or vibration. ˔ Keep Dry Keep the camera dry. Rusting of the internal mechanism caused by water inside the camera can not only be expensive to repair but can in fact cause irreparable damage. ˔ Avoid Sudden Changes in Temperature Sudden changes in temperature, such as those that occur when entering or leaving a heated building on a cold day, can cause condensation inside the device. To prevent condensation, place the device in a carrying case or plastic bag before exposing it to sudden changes in temperature. ˔ Keep Away from Strong Magnetic Fields Static charges or the magnetic fields produced by equipment such as radio transmitters could interfere with the monitor, corrupt data stored on the memory card, or affect the product's internal circuitry. ˔ Do Not Leave the Lens Pointed at the Sun Do not leave the lens pointed at the sun or other strong light source for extended periods. Intense light may damage the image sensor or cause fading or "burn in". Photographs taken with the camera may exhibit a white blur effect. 832 Technical Notes
