1.3 REPLACING THE CCD IMAGE SENSOR
䡵
The image sensor is interchangeable only with a specified
image sensor.
䡵
New image sensors and crystal filters should be handled so
as not to leave fingerprints or grease on their glass surfaces.
To remove attached dirt or grease, blow on the glass surface
until it becomes misted then wipe it gently with a cotton
swab. (Do not use alcohol or other similar substances.)
䡵
After replacement, all of the adjustments should be performed
from the beginning.
䡵
Note that the image sensor is susceptible to static damage.
Be sure to take anti-static measures before replacing it.
䡵
After an image sensor has been removed, an electrical charge
may remain on the terminals of the camera circuit for a cer-
tain period of time.
If a new image sensor is inserted into the socket in this con-
dition, the image sensor may be instantly damaged by the
remaining electric charge. To prevent this happening, wait a
while (2 to 3 minutes) after removing an image sensor until
inserting another one in the socket.
䡵
After the CCD board has been removed from the lens as-
sembly, the back-focus adjustment should be performed
again.
