13. Others About the Monitor/Viewfinder • Do not press the monitor with excessive force. Uneven colors may appear on the monitor and it may malfunction. • If the camera is cold when you turn it on, the picture on the Monitor/Viewfinder will be slightly darker than usual at first. However, the picture will return to normal brightness when the internal temperature of the camera increases. Extremely high precision technology is employed to produce the Monitor/ Viewfinder screen. However there may be some dark or bright spots (red, blue or green) on the screen. This is not a malfunction. Though the Monitor/Viewfinder screen parts are produced with highly controlled precision technology, some pixels may be inactive or always lit. The spots will not be recorded on pictures on a card. About the Lens • Do not press the lens with excessive force. • Do not leave the camera with the lens facing the sun as rays of light from the sun may cause it to malfunction. Also, be careful when placing the camera outside or near a window. • When there is dirt (water, oil, and fingerprints, etc.) on the surface of the lens, the picture may be affected. Lightly wipe the surface of the lens with a soft, dry cloth before and after taking pictures. • Do not place the lens mount facing downwards. Do not allow the lens mount contacts A to become dirty. • To improve the dust- and splash-proof performance, the mount of the interchangeable lens (H-HS12035) is embedded with the lens mount rubber. If you change the lens repeatedly, friction with the lens mount rubber may leave scratches on the camera's mount. However, those scratches do not affect the performance of this unit. For the replacement of the lens mount rubber, contact Panasonic. 413
