PRODUCT SAFETY NOTICE

Many electrical and mechanical parts have special safety-related characteristics. These are often not evident from visual
inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for a
higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this
Service Manual. Electrical components having such features are identified by marking with a on the schematics and
the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety
characteristics as the HITACHI recommended replacement one, shown in the parts list in this Service Manual, may create
shock, fire, or other hazards. Product safety is continuously under review and new instructions are issued from time to time.
For the latest information, always consult the current HITACHI Service Manual. A subscription to, or additional copies for,
HITACHI Service Manual may be obtained at a nominal charge from HITACHI SALES CORPORATION.

1 Flange back adjustment wheel

If focus needs to be adjusted after the lens has been mounted, loosen
the Flange back lock screw ( 7 ) and rotate the Adjustment wheel to
adjust.

2 DC iris level adjust POT

Adjust DC iris level manually.

3 BLC (Back Light Compensation) mode

switch
When strong light (sun, sky, illumination,
etc.) is present behind the object being
photographed, the object will appear dark.
In this case, put this switch in the BLC
position.

4 Sync mode switch

For setting the sync mode.

L.L.: Line Lock mode
INT.: Internal sync mode

5 Line phase adjustment POT

This POT is used to adjust phase when the Sync mode switch is set
to L.L. position.

CHAPTER 2 DISASSEMBLY

Procedure

CAUTION: Take great care when disassembling the block, because the components may be popped out by the

tension force of absorber (spring).
Reassemble the block, following instructions for "Reinstalling Front Block". Reassemble the other
components by the reverse procedure to removal.

(1) Remove the two screws and then the tripod base.
(2) Remove the screw and then the side panel.
(3) Remove the screw and then the back panel.
(4) Remove the five screws and then the main cover in the direction of the arrow.
(5) Remove the four screws, disconnect the flexible flat cable, and then remove the PCB2 assembly.
(6) Remove the two screws and then the PCB1 assembly. (*1) (*2)
(7) Disconnect the flexible flat cable.
(8) Remove the four screws and then the main base. (*3)

*1: The VK-M212E is not equipped with light shading rubber or crystal filter.
*2: The crystal filter will detach automatically: Be careful not to damage it.
*3: Hold the main base when removing the screws so that the CCD frame, FB adjust wheel and front spring plate do not pop

out by the tension force of absorber (spring).

REINSTALLING FRONT BLOCK

(1) Align portions A and A’.
(2) Align portions B and B’.
(3) While contracting the absorber, turn the CCD frame approx. 45° in the direction of the arrow to align portions C and C’.

Hold the absorber by hand until step (6) so that the absorber does not expand.
(4) Install the FB adjust wheel.
(5) Install the front spring plate so that hold D is set to the position shown in the illustration.
(6) Use the four screws to fix the main base.
(7) Use the screw to fix the locking plate.
(8) Install the crystal filter and light shading rubber (only for VK-C212E).
(9) Use the two screws to fix the PCB1 assembly so that hold E is set to the position shown in the illustration.

Note: Reinstall the other components using the reverse procedure to removal.
