3-3-2. REMOVAL OF CCD

1) Unsolder the CCD sensor leads from the sensor PWB.

2) Take out the sensor PWB.

3) Remove the two screws (6), and remove the sensor holder and CCD sensor.

3-3-3. MOUNTING OF CCD

1) Place the lens unit upright (since the CCD sensor mount ID faces upward, care must be taken so as not to damage the front lens of

unit),putthe crystal filterfirst and thenthedust protectionrubberinto the CCDholder of lensunit.Set thecrystalunit with itsthinside

toward the lens unit.

2) Place the CCD sensor so that the its No. 1 pin is at the right lower (Positioning hole to be at right), and put the CCD sensor into the

CCD holder. For smooth and tight fitting, press the right lower part of back of CCD sensor, and then press the left upper part.

Note: Pay attention to the direction of CCD sensor.

3) Placethesensorholdersothatitstworoundmarkingsbevisible,andfixthesensorholderwiththetwoscrews((6)LX-HZ0013TAFF).

4) Mount the sensor PWB so that the CCD sensor leads go thorough the PWB holes.

5) Solder the CCD sensor lead to the sensor PWB.

Note: Take care not to apply excessive heat.

3-3. REPLACEMENT OF CCD SENSOR

3-3-1. BEFORE REPLACEMENT

1) The CCD image sensor is more sensitive to electrostatic breakage than C-MOS LSI. Therefore sufficient means to prevent

electrostatic damage must be taken when it is replaced.

•Ground the soldering iron.

•Ground also the human body, using the wrist strap(through an 1 Mohm resistor).

•Until the CCD sensor is mounted on the PWB, fit it to the conductive sponge, and short-circuit the foot lead.

2) Takeutmostcaresothatthesurfaceglassof CCD sensor andopticalfilterarenotcontaminatedordamaged.If any contamination

is found, for example fingerprint, wipe it off with silicon paper or clean chamois skin.

3) When replacing the CCD sensor, perform quick soldering with a soldering iron which is grounded to prevent static electricity.
