1.4 REPLACEMENT OF COLOR CCD IMAGE SENSOR
䡵
The CCD image sensor is not interchangeable with any-
thing other than the specified one.
䡵
Be careful in handling a new image sensor neither to leave
fingerprints on the glass surface nor to make it stained with
grease.
To clean dust and greasy stain, breathe out to mist the glass
surface and gently wipe it with cotton swab, etc. (Do not
use alcohol and the like.)
䡵
After replacement of the CCD image sensor, the camera
needs to undergo electrical adjustment.
䡵
The image sensor has a weak characteristic in electrostatic
destruction. When replacing, make sure of electrostatic
shielding of the CCD image sensor.
䡵
For a while after removing the image sensor, there are elec-
tric charge remaining at the circuit terminals. If a new im-
age sensor is set into the socket in such a condition, it may
damage it in a moment because of stored electric charge.
When replacing the image sensor, wait a few (2 to 3) min-
utes after removing it before setting new one into the
socket.
