/ CCD BOARD ASSEMBLY (CAMERA SECTION AND BOARD ASSEMBLY)
2.6.1 Precautions
(1) Take care in handling the CCD IMAGE SENSOR, OP LPF
and lens components when performing maintenance etc.,
especially with regard to surface contamination, attached
dust or scratching. If fingerprints are present on the surface
they should be wiped away using either a silicon paper,
clean chamois or the cleaning cloth.
(2) The CCD IMAGE SENSOR may have been shipped with a
protective sheet attached to the transmitting glass. When
replacing the CCD IMAGE SENSOR, do not peel off this
sheet from the new part until immediately before it is
mounted in the OP BLOCK ASSEMBLY.

(5) Remove the OP LPF.
2.6.3 Assembly of CCD BASE ASSEMBLY and CCD
BOARD ASSEMBLY
(1) Set the OP LPF to the OP BLOCK ASSEMBLY so that the
OP side touches the OP BLOCK ASSEMBLY.
NOTE 2a:
Pay careful attention to the orientation of the OP LPF.
(2) Set the SHEET to the OP LPF not to come off the right
position.
(3) Attach the SPACER to the OP BLOCK ASSEMBLY.
(4) Fasten them together with the two screws (1, 2).
(5) Set the CCD BOARD ASSEMBLY in the CCD BASE
ASSEMBLY, and then solder it by the 14 points (SD2).

This helps prevent the tape from being damaged when
the CASSETTE HOUSING ASSEMBLY is moved up-
ward at the unloading end.
(4) Apply DC 3V to the electrode on the top surface of the
LOADING MOTOR ASSEMBLY to set the MECHANISM
ASSEMBLY to the EJECT mode.
Unloading end is EJECT mode.
(5) If there is any slack tape in the tape transport system, wind
it inside the DVC CASSETTE TAPE by turning the REEL
DISK ASSEMBLY (SUP) from the backside of the SLIDE
DECK ASSEMBLY.
(6) Peel off the PVC TAPE and take out the DVC CASSETTE
TAPE from the CASSETTE HOUSING ASSEMBLY.

3.4 MECHANISM COMPATIBILITY ADJUSTMENT
3.4.1 Tape pattern check
(1) Connect the JIG CONNECTOR CABLE to the set.
As for the connection procedure, JIG CONNECTOR
BOARD and see 3.5 ELECTRICAL ADJUSTMENT.
(2) Remove the COVER(ADJUST)
(3) Play back the compatibility adjustment tape.
(4) While triggering the HID1, observe the waveform of
ENV_OUT.
(5) Confirm that the waveform is free from remarkable level-
down, and entirely parallel and straight.
(6) In case any level-down is observed on the left hand side,
straighten the level by turning the GUIDE ROLLER (SUP)
of the POLE BASE ASSEMBLY.
In case any level-down is observed on the right hand side,
however, straighten the level by turning the GUIDE ROLL-
ER(TU) of the POLE BASE ASSEMBLY.
(7) After adjustment, try the unloading motion once, and con-
firm that the waveform is flat (straight) when the tape has
been played back again.
Moreover, perform readjustment as required.
(8) When the recording has been played back again, play back
the self-recording to confirm that the waveform is flat.
