1. IMPORTANT SERVICE NOTES
BEFORE RETURNING THE VIDEO CAMERA
RECORDER
Before returning the video camera recorder to the user,
perform the following safety checks.
1. Inspect all lead dress to make certain that leads are
not pinched or that hardware is not lodged between
the chassis and other metal parts in the video camera
recorder.
2. Inspect all protective devices such as non-metallic
control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields, isolation resistor/capacitor networks, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
· Plug the AC line cord directly into a 120 volt AC outlet
(Do not use an isolation transformer for this test).
· Using two clip leads, connect a l.5k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all
exposed metal cabinet parts and a known ground,
such as a water pipe or conduit.
· Use a VTVM or VOM with 1000 ohm per volt, or higher
sensitivity or measure the AC voltage drop across the
resistor (See Diagram).
· Move the resistor connection to all exposed metal
parts having a return path to the chassis (antenna
VL-E990E
connections, metal cabinet, screw heads, knobs and
control shafts, etc.) and measure the AC voltage drop
across the resistor. Reverse the AC plug (a non
polarized adaptor plug must be used but only for the
purpose of completing these checks) on the set and
repeat the AC voltage measurements for each exposed metallic part. Any reading of 0.45V rms (this
corresponds to 0.3mA rms AC.) or more is excessive
and indicates a potential shock hazard which must be
corrected before returning the video camera recorder
to the user.

Note:
• Replace if anything is abnormal
(including the noise).
• Replace any part that fails to
perform within the standard.
Remarks
Apply oil to the shaft, then
wipe lightly with a cloth.
6-2. 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 or less.
(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.

adhesive tape and referring to 9-3, operate in the TEST mode (T01) to rewind,
and set the rewinding playback (VS-REW) mode.
(2)Set the torque gauge on the S reel base, press the front end of tension post with
your finger in the arrow A direction so as to ascertain that the winding torque is
as specified. (Check without rotating the torque gauge.)
1.6 ± 0.6mN·m, ripple 0.5mN·m or less
(3)After checking the winding torque remove the torque gauge, and remove the
adhesive tape used in item (1) above (refer to 9-3). The STANDBY mode is set
automatically.

7-3. Checking of reel base height DC3V, without cassette controller assembly (Independent Mechanism)
(1)Remove the cassette controller assembly (refer to 9-2).
(2)Referring to 9-1, apply DC3V to the loading motor and put the system into playback mode.
(3)Taking adequate care so that the master plane does not contact drum, running parts (guide roller, etc.), or the MIC contacts. Fit
the master plane holes to the 2 guides (A and B) in Fig. 2.
(4)Confirm that the heights of the S reel base reel receiving surface and the Tu reel base reel receiving surface below the master plane
top surface are within the set values, using, for example, a slide calliper (Fig. 3).
When checking the S reel base height, press the front end of tension post in the arrow A direction with your finger to release the
tension band, and then check the height in this state (Fig. 1).

10. 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).
Chip ID as per Digital Interface IEEE1394 Standard
The VL-FD1U and other models that follow are newly equipped with the digital interface function. The Digital Interface
IEEE1394 Standard stipulates that each set with the digital interface function be given its specific ID number. The ID
number is written on the E2PROM of the set while it is manufactured. If the E2PROM alone or the PWB having this E2PROM
on it has been replaced for repair purpose, it is necessary to write a new ID number again. (Note that any replacement
part does not have an ID number yet.)
Accordingly, the repair engineer must obtain the new ID number.

2) FLASH MEMORY (IC7702) on main unit
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.
PROM contains the adjustment item data as shown below. If it is changed, data rewriting and confirmation of latest

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, the auto-focus function adjustment is required:
• When the lens has been replaced
• When the CCD has been replaced
2
• When the E
PROM (IC1001) has been replaced
1) Shifting to the auto-focus function adjustment mode
Set the data for the address "09FE" 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 "09FE" 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.
(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 mode 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.

1) When replacing E
Since the adjustment data of gyro is written in IC1001, copy the data of addresses "864, 865" and rewrite them after
replacement.
2) When replacing the gyro sensor: S1501
After replacing with the specified gyro sensor, write the following data in the addresses "864, 865".

VL-FD1U
Item
(1) Auto-focus adjustment
Set the unit to the auto-focus function adjustment mode and write data to the address "09FD" 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.
AddressDataAdjustment item
09FD000CMR censor adjustment
0012WIDE end adjustment
0008TELE end focus ∞ position adjustment
0006WIDE end focus ∞ position 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.
In the camera signal system adjustment mode (write the address "0000" to, " 00") . Set the unit to the adjustment mode and
write data to the address "09FD" one after another. This executes the adjustments automatically. The items to be adjusted are
as listed below. Every time an adjustment is made properly, the data "00FF" is written to the address.
AddressDataAdjustment item
09FD0009Hall offset adjustment

* After completion of 1. Auto-focus adjustment, 2. Iris basic adjustment once restore the regular operation mode. Data "090F" is
written in the address "0003".
(3)Black balance adjustment/A/F noise adjustment
1) Prior to the adjustment, initialize the data for the addresses "0224", "0226", "0228", "022A", "022C", "022E".
Write " FF" (the last two digits are effective) 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.
