1. SERVICE NOTE

ENGLISH JAPANESE

1-1. CHEMICALS

Some chemicals used for servicing are highly volatile.
Their evaporation caused by improper management affects your health and environment, and wastes resources.
Manage the chemicals carefully as follows.

• Store chemicals sealed in a specific place to prevent from exposure to high temperature or direct sunlight.

•Avoid dividing chemicals into excessive numbers of small containers to reduce natural evaporation.

•Keep containers sealed to avoid natural evaporation when chemicals are not in use.

•Avoid using chemicals as much as possible. When using chemicals, divide only required amount to a small plate from the container and
use up it.

1-2. EXTERIOR PARTS

Be careful to the following points for plastic parts used in this unit.

• Use a piece of cleaning paper or cleaning cloth for cleaning plastic parts. Avoid using chemicals.
Even if you have to use chemicals to clean heavy dirt, don’t use paint thinner, ketone, nor alcohol.

• Insert the specific screws vertically to the part when installing a plastic part.
Be careful not to tighten screws too much.

1-3. UNLEADED SOLDER

This unit uses unleaded solder.
Boards requiring use of unleaded solder are printed with the lead free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)

: LEAD FREE MARK

Be careful to the following points to solder or unsolder.

• Set the soldering iron tip temperature to 350 °C approximately.
If cannot control temperature, solder/unsolder at high temperature for a short time.
Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful!

Unleaded solder is more viscous (sticky , less prone to flow) than ordinary solder so use caution not to let solder bridges occur
such as on IC pins, etc.

• Be sure to control soldering iron tips used for unleaded solder and those for leaded solder so they are managed separately. Mixing
unleaded solder and leaded solder will cause detachment phenomenon.

1-4. SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and

bridges.

2. Check the interboard wiring to ensure that no wires are “pinched” or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the

customer and recommend their replacement.

4. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their

replacement.

5. Check the B+ voltage to see it is at the values specified.

6. Flexible Circuit Board Repairing

•Keep the temperature of the soldering iron around 270 °C during repairing.

• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering or unsoldering.

Danger of explosion if battery is incorrectly replaced.

CAUTION

Replace only with the same or equivalent type.

1-1. 各種薬品の取り扱いについて

現在使用されている薬品の中には揮発性の高い薬品もあります。
それらを不用意に取り扱い蒸発させてしまうと，環境や健康へ影響を与えたり，資源の無駄使いになります。
各種薬品は，下記の点に注意して取り扱ってください。

・ 保管場所を定め，高温になったり直射日光の当たらない場所に密閉して保管してください。
・ 小分け（ハンドラップ等）する数は必要最小限に留め，容器による自然蒸発を防いでください。
・ 作業に使用しない時は，必ずキャップ等をして自然蒸発を防いでください。
・ 薬品を使用する回数を極力少なくし，使用する場合は使用する量だけ容器より出して受け皿に残さないようにしてくだ

さい。

1-2. 樹脂系部品の取り扱いについて

本機に使用されている樹脂系の部品は，下記の点に注意して取り扱ってください。

・ 清掃には薬品を使用せず，清掃紙や清掃布を使用してください。

やむを得ず汚れがひどくて薬品を使用する場合は，シンナー，ケトン，エーテルは使用しないでください。

・ 各部品の取り付けには指定されたねじを使用し，部品に対して垂直に取り付けてください。

また，ねじを締め付ける時は，無理な力を加えないでください。

1-3. 無鉛半田について

本機には無鉛半田が使用されています。
無鉛半田を使用している基板には，無鉛（LeadFree）を意味するレッドフリーマークがプリントされています。
（注意：基板サイズによっては，無鉛半田を使用していてもレッドフリーマークがプリントされていないものがあります）

：レッドフリーマーク

無鉛半田は，下記の点に注意して使用してください。

・ 半田こてのこて先温度は約350℃に設定してください。

温度調節が無理な場合は，高温短時間で作業を行ってください。
注意： 半田こてを長く当てすぎると，基板のパターン（銅箔）がはがれてしまうことがありますので，注意してくださ

い。また，従来の半田よりも粘性が強いため，IC端子などが半田ブリッジしないように注意してください。

・ 半田こてのこて先は，必ず無鉛半田用と有鉛半田用に分けて管理してください。

無鉛半田と有鉛半田が混在すると剥離現象が発生してしまいます。

NOTE FOR REPAIR

2. DISASSEMBLY

• Make sure that the flat cable and flexible board are not cracked of bent at the terminal.
Do not insert the cable insufficiently nor crookedly.

• When remove a connector, don’t pull at wire of connector. It is possible that a wire is snapped.

• When installing a connector, don’t press down at wire of connector.
It is possible that a wire is snapped.

• Do not apply excessive load to the gilded flexible board.

Cut and remove the part of gilt
which comes off at the point.
(Be careful or some
pieces of gilt may be left inside)

DISCHARGING OF THE ST-196 BOARD’S CHARGING CAPACITOR (C901)

The charging capacitor (C901) of the ST-196 board is charged
up to the maximum 330 V potential.
There is a danger of electric shock by this high voltage when the
capacitor is handled by hand. The electric shock is caused by
the charged voltage which is kept without dischar ging when the
main power of the unit is simply turned off. Therefore, the
remaining voltage must be discharged as described below.

Preparing the Short Jig

To preparing the short jig, a small clip is attached to each end of
a resistor of 1 kΩ /1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to
prevent electrical shock.

Note: High-voltage cautions

Discharging the Capacitor

Short-circuit between two points
with the short jig about 10 seconds.

2-3. IMAGER INCLINATION ADJUSTMENT

Checking Method

1. Use the copy stand or place a mirror on the wall, and adjust the accuracy so that the camera is opposed to the mirror.

2. Use the AE master lens as an inspection lens.

3. Obtain the inclination angle with the Photoshop, and perf orm as follows according to the angle:

• For the angle above ± 1.0 degree, be sure to repair the camera.

• For the angle abov e ± 0.5 degree and below ±1.0 degree, repair the camera according to the user's requirement level.

• For the angle below ± 0.5 degree, check again the angle to satisfy the specified value.

Adjusting Method

1. Loosen the fixed screw.

2. Adjust the inclination with the adjusting screw.

• For an image that tilts to the right, rotate the screw clockwise.

• For an image that tilts to the left, rotate the screw counterclockwise.

3. Tighten the fixed screw.

2-5. IRIS RING REMOVAL/INSTALLATION

Removal

Rotate the iris ring clockwise, and remove it at the stop position (iris-in end).
At this time, do not rotate the iris joint gear of the Aperture Unit.

Installation

1. With the Aperture Unit set in the charge position (see "2-7. Aperture Unit Charge Position Setting" ), install it on the front
frame set.
* The Aperture Unit has been set in the charge position, if it is not removed.
However, the iris ring must be in the removed state (where the iris joint gear is not rotated).

2. Install the iris ring with it's a punch mark aligned with a line that connects the iris joint gear shaft and the optical axis center.

2-6. APERTURE UNIT INSTALLATION

*The Aperture Unit is supplied by being set in the charge position (initial position), but if this position is disordered when the

Aperture Unit is removed, or if the charge position is to be set again, perform as follows.

*Refer to "2-7. Aperture Unit Charge Position Setting" for the confirm method at the charge position.

2-7. APERTURE UNIT CHARGE POSITION SETTING

1. Check that the Aperture Unit is in a free state.

2. After confirming that the Aperture Unit is in a free state, rotate the gear by 3 turns.

3. After rotating the gear by 3 turns, set the Aperture Unit where the holes in the gear and the Aperture Unit coincide. This
position is the charge position.
*Refer to "2-8. Aperture Unit Free Position Setting" for the setting and the confirm method at the free position.

2-8. APERTURE UNIT FREE POSITION SETTING

1. Set the Aperture Unit to a free position once, if the gear was rotated accidentally and the charge position is disordered, or if
the charge position was shifted during disassembly.

Gear rotating
direction to set
the charge position

In a free state, the edge of this spring
will move up and down about 1 mm if
the gear is moved a little.

Gear rotating
direction to make
the unit free

In a free state, a hole in the gear almost
coincides with a hole in the Aperture Unit.

As viewed from gear
(Hole in the gear)

First, check the spring edge position.

If the edge of spring is located downward,
rotate the gear in the arrow direction to
search a free position.

* In a free position, the edge of spring is

located upward.

Note: The spring is deformed and cannot

be used if the gear is rotated too
much from a free state.
