GENERAL SAFETY PRECAUTIONS
PRODUCT COMPLIES WITH DHHS PULES 21CFR SUBCHARTER J APPLICABLE AT DATE OF MANUFACTURE SAFETY PRECAUTION
GENERAL GUIDELINES
1.
When service is required, observe the original lead dress. Components, wires or cables that indicate evi- dence of overheating or other electrical or mechanical damage should be replaced.
After servicing the camera, power supply and electronic viewfinder, all the protective devices, such as insulation tape, shields and isolation R-C combinations must be properly installed.
Potentials as high as 5KV are present when the electronic viewfinder is operating. Operation without the camera head side covers, finder case ass’ys of electronic viewfinder and covers of power supply unit pres- ents a danger of shock hazard from the camera power supply.
Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions that should be taken when working on high-voltage equipment. Always discharge the anode of the picture tube to the main chassis before handling the tube.
After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
LEAKAGE CURRENT COLD CHECK
Conduct this test on the power supply unit with the camera disconnected and repeat with the camera power supply unit and electronic viewfinder properly assembled. Also, repeat test with and without available approved accessories/cables/connectors.
Turn the AC switch on.
Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed termi- nal, screwheads and coaxia! connector.
The resistance measured should not be less than (infinity).
Any resistance value below this range indicates an abnormality which requires corrective action.
Repeat the test with the AC switch in the “off” position.
LEAKAGE CURRENT HOT CHECK
Conduct this test on the power supply unit with the camera disconnected and repeat with the camera, power supply unit and electronic viewfinder properly assembled. Also, repeat test with and without available approved accessories/cables/connectors.
Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. Connect a 1.5K 10 watt resistor, paralleled by 0.15\1F capacitor, between each exposed metallic part on the unit and a good earth ground such as a water pipe, as shown in figure 1.
Use an AC voltmeter, with 10002 /volt or more sensitivity, to measure the potential across the resistor . Check afl exposed metallic parts of the cover (Cable connection, Handle bracket, metallic cabinet, Screwheads, Metallic overlays, etc), and measure the voltage at each point.
Reverse the AC plug in the AC outlet and repeat each of the above measurements.
The potential at any point should not exceed 0.75 V RMS.
A leakage current tester (FLUKE MODEL: 8000A equivalent) may be used to make the hot checks. Leakage current must not exceed 0.5 milliamp.
In case a measurement is out side of the limits specified, there is a possibility of a shock hazard, and cor - rective action must be taken before returning the instrument to the customer.

RADIATION
The potential source of x-radiation in electronic viewfinder is the high-voltage section and picture tube. It is important to use a periodically checked and accurate high-voltage meter, to monitor and check the high voltage.
Rotate the brightness control and contrast fully counterclockwise for this test.
Observe that the high voltage does not exceed the specified value.
Excessive high voltage may cause a possible x-radiation hazard.
The camera system should be repaired as soon as possible.
It is essential to use the specified picture tube to avoid a possible x-radiation hazard.
ELECTROSTATICALLY SENSITIVE (ES) DEVICES
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor ‘chip’ components. The following techniques shouid be used to help reduce the incidence of component damage caused by static electricity.
1.
Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercial- ly available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test.
After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
Use only a grounded-tip soldering iron to solder or unsolder ES devices.
Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static” can generate electrical charges sufficient to damage ES devices.
Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.
Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material).
Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed. CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such
as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES device).

Electrical Adjustment Procedures Preparations:
To achieve the best adjustment results, warm up the camera for approximately 30 minutes before adjusting.
To prevent short-circuits between the camera body and the undersides of the process and deflection circuit boards, place insulating tape on those portions of the circuit boards that may come in contact with the camera body.
Note: All board drawings and adjustments are referenced to the foil side of the printed circuit board.
[1] +9V ADJUSTMENT
Cautions:
Adjust the voltage to +9 volts. This adjustmert should al-
ways be performed before any other camera adj sstments as
voltage adjustment will affect overall camera adjustment.
Unless complete camera alignment is to be periormed, it is
not necessary to adjust the voltage if the errors less than +0.02 volts.
1. To adjust the voltage to +9 volts, connecta voltmeter to the +9 volt regulator at test point TP%O5 on the deflection circuit board.
2. Adjust +9V contro! VR6001 so that the volsneter indi- cates +9 volts + 0.01 volts.
