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.
