If the camera is exposed to an electronic interference, it will turn itself off to protect the memory card.
Camera Maintenance
-Use a soft brush (available from photo stores) to gently clean the lens and LCD assemblies. If this does not work, lens-cleaning paper with lens cleaning fluid can be used.
Clean the camera body with a soft cloth. Do not allow this camera to come into contact with solvent materials such as benzol, insecticide, thinners etc. This may damage the body shell of the camera and also affect its performance. Rough handling can damage the LCD monitor. Take care to avoid damage and keep the camera in its protective carry case at all times when not in use.
Do not attempt to disassemble or modify the camera.
Under certain conditions, static electricity can cause the flash unit to fire. This is not harmful to the camera and is not a malfunction.
When images are uploaded or downloaded, the data transfer may be affected by static electricity. In this case, disconnect and re-connect the USB cable before trying the transfer again.
