Power Supply

• Use only the special rechargeable lithium ion battery (NP-50) to power this camera. Use of any other type of battery is not supported.

• The camera does not have a separate battery for the clock. The date and time settings of the camera are cleared about 12 hours after power is totally cut off (from both the battery and USB cradle). If this happens, be sure to reconfigure these settings after power is restored.

LCD Panel

• The liquid crystal panel of the monitor screen uses high-precision technology that provides a pixel yield in excess of 99.99%. This means that some pixels may not light or may remain lit at all times. This is due to the characteristics of the liquid crystal panel, and does not indicate malfunction.

Lens

• Never apply too much force when cleaning the surface of the lens. Doing so can scratch the lens surface and cause malfunction.

• You may sometimes notice some distortion in certain types of images, such as a slight bend in lines that should be straight. This is due to the characteristics of lens, and does not indicate malfunction of the camera.

Special AC Adaptor

• Power cord precautions for use in Singapore The power cord set is not supplied. The power cord used must comply with relevant national and/or international standards.
