wipe lightly with a cloth.

5-2. Precautions

(1) When replacing any part, always replace the cut washer that was

removed with a new one.

(2) This mechanism does not have control adjustment. If the control

cannot be set as required, clean and or replace parts.

(3)On the oil

a) Always use the specified oil. (Using another kind of oil can cause

various kinds of trouble.)

b) Always use clean oil, without any mixed-in dirt, to lubricate bearings.

(Using oil with dirt mixed in can cause the bearings to wear or to
stick.)

c) One drop of oil is the amount shown in the Fig. 1, on the point of a

pin.

(4)Perform circuit repair, tape running adjustment, etc. with the cassette

controller assembly attached to the mechanism.

(5)When operating the mechanism separately, apply voltage to the

loading motor. However, the terminal voltage must be DC3V~4V.
(When the mechanism is connected to the main PWB, do not apply
external voltage to the loading motor. It may cause a trouble.)
(Forcing the gears to turn by hand entails danger of breakage.)
If the mechanism is separated from the unit, the capstan motor may rub
and be damaged if spacing under the mechanism is inadequate.

(6)To install the cassette controller, push section A in the Fig. 2. Do not

push anything else.

(7)Do not deform any of the mechanical parts.

8-3. How to operate with the circuit board without the cassette controller assembly.

In this method, if the procedure is followed incorrectly there is danger of damaging the mechanism and the tape, so except in special
cases, such as when measuring the VSR torque, do not perform this procedure. Normally operate this unit with the cassette controller
assembly attached.
Be sure to follow each caution mentioned.

(1) Apply DC3 ~ 4V to the loading motor to enter the standby mode.
(2) Securely press the movable piece

9. ADJUSTING THE ELECTRICAL CIRCUITS

Before starting the electric circuit adjustment

• The adjustment methods described herein are used, in most cases, when the expendable mechanical parts, including
the video head, have been replaced, at which time the electrical circuits need to be readjusted. Before adjusting the
electrical circuits, make sure that the mechanism works properly (i.e., the mechanism is properly adjusted). Incase of
the occurrence of any problem to the electrical circuits, be sure to use the specified measuring instruments to locate
the area to which the problem is occurring, and then take the necessary action, including repair, replacement or
adjustment, exactly as instructed in the electrical adjustment methods that will follow.
Do not attempt to make adjustments without using the proper measuring instruments.

• This machine is configured so that the electrical circuits inside its PWB unit are composed, for the most part, of high­density, small surface-mounted component parts for downsized machine body.
To perform repair service or parts replacement, do so using a soldering iron, but in as short a time as possible; this is
because surface-mounted component parts are generally so small in size and susceptible to heat, as compared with
the large discrete parts used in TV sets, desk-top video decks, etc., that attempting to heat their electrodes for a longer
time than is necessary with a soldering iron may result in their becoming defective.
This applies particularly when replacing the laminated chip capacitors.
For this purpose, ceramic soldering irons with a temperature regulator are recommended (iron tip temperature 250°C
and soldering time 5 seconds or shorter).

5) When the adjustment is complete:
Press the "CONTINUE" key to let the "CAM ADJ" display disappear from the screen.
Note: Before terminating the adjustments, make sure that the adjustment mode is neither the auto-focus function adjustment

mode nor the camera signal system adjustment mode (these modes are mentioned later).

• Camera unit adjustment modes
The camera unit is adjusted in two types of modes: the auto-focus function adjustment mode and the camera signal system
adjustment mode.

Note: E

2

PROM contains the adjustment item data as shown below. If it is changed, data rewriting and confirmation of latest data

must be performed.

1) E2PROM(IC705) on the Main unit
Lens data and Signal system adjustment data

(3)Auto-focus function adjustment mode

• The camera unit uses a microprocessor-controlled auto-focus zoom lens.
The auto-focus circuit incorporated in this unit is designed to execute the image processing where the focusing action is done by
taking advantage of the fact that the high-frequency components in the image signals increase as the focus intensifies. Moreover,
to achieve high magnifying power with a small lens, the camera unit incorporates the inner focus system in which the focus is shifted
by moving the master lens (rear lens) back and forth. This inner focus system is a full-range focus type by which the focus can be
shifted from approximately 10 mm to the infinity. It should be noted, however, that since the closest subject distance at the telephoto
end is fixed at 1.5 m, subjects in a closer range than 1.5 m at the telephoto end will be out of focus. For this reason, the unit is
designed so the zoom control is automatically shifted to the wide angle side until the position is found where the subject can be
focused on.

In the auto-focusing system of this until, the following constitute the important factors:

• Master lens position detection data

• Iris position detection data

• Zoom lens position detection data

2

These detection data are handled and stored by the microprocessor, lens by lens, into the E

PROM.

Therefore, in the following cases, (3) auto-focus function adjustment is required:

• When the lens has been replaced

• When the CCD has been replaced

2

• When the E

PROM has been replaced

• When the CCD PWB and Camera PWB has been replaced

1) Shifting to the auto-focus function adjustment mode
Set the data for the address "0000" to " 01".

]

This makes the screen fade temporarily in white and shifts to the auto-focus function adjustment mode.

* When this adjustment mode has been shifted to, make the adjustment according to (5) Camera unit adjustment procedure.
* In this adjustment mode, the lens can not be operated.

2) Shifting to the normal operation mode
Set the data for the address "0000" to " FF".

]

This makes the screen fade temporarily in white and shifts to the normal operation mode.

]

Press the "CONTINUE" key, and the "CAM ADJ" display goes out of the screen, enabling the normal operation.

33

VL-NZ50S/H/E/W/NZ80H
VL-NZ100S/H/E

(4)Camera signal system adjustment mode

In the camera signal system adjustment mode, the automatic white balance is disabled to allow for the adjustment of the camera
unit. At this time, the white balance mode is fixed at the INDOORS mode and the focus mode is switched to the manual focus mode.

1) Shifting to the camera signal system adjustment mode
Set the data for the address "0000" to " 00".

]

This shifts the camera signal system adjustment mode.
* When this adjustment mode has been shifted to, make the adjustment according to (5) Camera unit adjustment procedure.

2) Shifting to the normal operation mode
Set the data for the address "0000" to " FF".

]

This shifts the mode to the normal operation mode.

Item

(1) Auto-focus adjustment

Set the unit to the auto-focus function adjustment mode and write data to the address "0000" one after another. This executed
the adjustments automatically. The items to be adjusted are as listed below. Every time an adjustment is made properly, the data
"FF" is written to the address. After each adjustment, make sure that the adjustment has been made properly, and then go on to
the next adjustment item.

Address Data Adjustment item

0000 0012 WIDE end adjustment

0006 WIDE end focus ∞ position adjustment
0008 TELE end focus ∞ position adjustment

000D Zoom tracking adjustment

Note 1: To adjustment of ∞ position is executed by actually picking up the image of subject. For this adjustment use the subject with

clear profile.
Especially, if the adjustment of TELE end focus ∞ position is made without picking up the image of remote subject,
adjustment failure may occur.

Adjustment of WIDE end focus ∞ position: 3 m or more
Adjustment of TELE end focus ∞ position: 50 m or more

Note 2: In case of ∞ position adjustment the field depth is important to ensure the adjustment accuracy. If the field depth is high,

the focus becomes too stable , which may cause incorrect adjustment of ∞ position. Therefore the adjustment must be made
with low field depth (with iris opened).

The iris can be opened with the high-speed shutter.

1. It returns to the normal operation mode.

2. In the normal operation mode, set the high-speed shutter mode until the iris is opened. (Refer to the operation manual.)

3. Display “CAM ADJ” with the remote control for service.

4. It shifts to the auto-focus adjustment mode.

5. Perform the ∞ position adjustment.

6. After completing the ∞ position adjustment, return the high-speed shutter mode to the normal mode.

Adjustment method

(2)Iris basic adjustment

This is for adjusting the operating point of the hole element installed in the iris meter of the lens.
The adjustment is automatically done by sequentially writing the data at the address "0001" in the camera signal system
adjustment mode.The items to be adjusted are as listed below. Every time an adjustment is made properly, the data "00FF" is
written to the address.

Address Data Adjustment item

0001 0009 Hall offset adjustment

000A Iris offset adjustment
000B Iris close adjustment

In the camera signal system adjustment mode (write the data " 00" to the address "0000"), set the unit to the
adjustment mode.

(3) Black balance adjustment/ A/F noise adjustment

1) Prior to the adjustment, initialize the data for the addresses "0026", "0028", "002A", "002C", "002E", "0030".
Write " FF" to all of these address.

2) Write the data " 01" to the address "0001" This starts the adjustment automatically.
When the adjustment is completed properly, the data "00FF" is written automatically.
