Consequently, when servicing these products, replace the cath- ode ray tubes and other parts with only the specified parts. Conductors extended Under no circumstances attempt to modify these circuits. Wire insulation recessed Unauthorized modification can increase the high voltage value more than 4 mm and cause X-ray emission from the cathode ray tube. Fig.7, v Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have been returned to original positions, Afterwards, perform the following tests and confirm the specified values in order to verify compli- ance with safety standards. 1. Leakage current test Confirm specified or lower leakage current between earth ground/power cord plug prongs and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.). a b Measuring Method : (Power ON) cExternallyZAInsert load Z between earth ground/power cord plug prongs and externally exposed accessi- exposed V ble parts. Use an AC voltmeter to measure across both terminals of load Z. See figure 9 and accessible part following table 2. Fig. 8 2. Grounding (Class 1 model only) Confirm specified or lower grounding impedance between earth pin and externally exposed accessible parts (Video in, Video out, Audio in, Audio out or Fixing screw etc.).

Warnings for accident prevention in handling battery

WARNING: Fire, Explosion, Leakage and Burn Hazard. Do not recharge, Disassemble, Heat Above 212°F, Incinerate, Or Expose Contents To Water. Be Sure The Battery Is Inserted In The Right Direction. The lithium battery incorporates inflammable substances such as lithium and organic solvent, etc. inside. If the lithium battery is handled in a wrong way, it may cause injury, fire and other dangerous accident caused by heating, bursting, firing, etc. Be sure to follow the instructions mentioned below to prevent you from an unexpected accident before unpacking, in and after using the battery. 1. Be careful of short-circuit. If the positive (+) and negative (-) terminals come into contact with each other or with other metallic material, the battery is shortcircuited. If many batteries are left disorderly and their terminals are in contact with others, some of the batteries may generate heat, burst or fire and resultingly cause accident. 2. Neither immerse battery in water nor throw it into fire. If the lithium battery is immersed in water or thrown into fire, it may fire or burst violently. 3. Avoid heating the battery. If the lithium battery is heated at a temperature of 100°C or more, the electrolyte may leak from the battery because the plastic materials such as gasket and separator are damaged or the battery may burst or fire because the battery is heated by internal shortcircuit. 4. Avoid directly soldering the battery. If the lithium battery is directly soldered, the electrolyte may leak from it because the plastic materials such as the gasket and separator are damaged or the battery may burst or fire because it is heated by internal shortcircuit. 5. Avoid charging the battery. If the primary battery is charged, the battery may generate gas inside and it may resultingly cause expansion, burst or fire of the battery. 6. Avoid dismantling the battery. If the lithium battery is dismantled, some kind of gas is generated and it stimulates the throat or the dismantled battery may fire because the negative lithium reacts on water and generates heat. 7. Avoid deformation with pressure. If the lithium battery is deformed with pressure, the electrolyte may leak from it because of warp or damage in the sealing, or the battery may burst or fire because it is heated by internal shortcircuit. 8. Don’t use batteries of different types or old ones mixedly. If batteries of different brands/types are mixedly used or new and old batteries are mixedly used, it may cause expansion, burst or fire of the batteries because they are over-discharged by difference in their characteristics of voltage, capacitance, etc. 9. Avoid setting of the battery in wrong polarities. If the battery is set in wrong polarities (+ and - poles are set reversely), the battery may be shortcircuited and it may resultingly cause heating, bursting or firing in the battery. 1-3, 1.7 SERVICE CAUTIONS 1.7.3 Connection of the wires 1.7.1 Precautions 1.

In general, chip parts such as resistor, shorting jumpers (0- ohm resistor), ceramic capacitors, diodes, etc. can not be reused after they were once removed. 4. When installing parts, be careful not to do with other parts as well as not to damage others. 5. When removing ICs, be careful not to damage circuit pat- terns. 6. Tighten screws properly during the procedures. Unless speci- fied otherwise, tighten screws at torque of 0.196 N·m (2.0 Connector kgf·cm). 1.7.2 How to read the disassembly and assembly Fig. 1-7-1 (For Cabinet Parts)

SECTION 3 INSTALLATION MANUAL

For installing and operating the system which this camera is incorporated in, be sure to follow the instructions mentioned below. 1. Use the AA-V31U isolation transformer to supply the power to every unit of the system. 2. Ground the AA-V31U. (Please refer to “4. Check of grounding (AA-V31U)”) 3. Cover disused power outlets of the AA-V31U with protection brackets respectively. 1. Safety precautions • Before starting installation, carefully read “Safety precautions” appearing on pages 4 to 8 of the instructions. 2. Connection of system components • Connect each unit referring to “Connection” appearing on page 9 of the instructions. • Please install isolation transformer near the equipotential terminal of video cart. • When installing the system, power supply cords should be routed so that they are not pinched by items placed upon or against them. Besides that, when moving the system, please pay special attention to power cords as the cart will not be fallen down. Please do not connect other equipment to the signal in - or outputs during use of the system at the patient - unless you are using facility for galvanic separation, e.g. electro-optical transimitter. The system may not be changed without additional checking of the safety provisions of EN 60601-1-1. Please note that the party (person or company) which is assembling, installing or modifying a medical sytstem is responsible that it complies with all relevant requirements of that standard. 3. Connection of each unit to the power supply unit • Connect the power cable of each unit to the isolation transformer (AA-V31U) referring to the following figure. The plug of each power cable must be fastened by a band and a holder, which needs to be fastened with a screw- driver. Washer Use exclusive screws to fasten Cover disused power outlets of the the plug and tighten the screws AA-V31U with exclusive protection with the special screwdriver. brackets, (Pay need to the orientation of and fasten each protection bracket each screw.) with exclusive screws that need the special screwdriver for tightening. When fastening the band to the AA-V31U with an exclusive screw, be sure to put two washers (two different types) on the screw so that they are inserted between the band and the AA-V31U. • When fitting the cover to the DZ-VCA3U for medical use, be sure to disconnect the power cord from the AC outlet in the hospital/clinic to avoid getting an electric shock. • Be careful not to insert a screwdriver or the like into the AC outlet. 3-1, 4. Check of grounding (AA-V31U) • If the AA-V31U is connected to an AC outlet that is not grounded or is poorly grounded, the indicator lamp of the AA- V31U goes on. In such a case, reconnect the AA-V31U to another AC outlet that is perfectly grounded. 5. Check of operation • Check main operations of the system referring to the instructions. 6. Liaison slip of customer data • When all the above-mentioned work is complete, fill out the liaison slip of customer data and send it to the sales office concerned. 7. Sterilization When returnings to repair this camera, the camera head must be sterilized by following the instructions of the steriliz- ing app aratus referring to the following example of sterilization. Example of sterilization • Sterilization by ethylene oxide gas Gas composition : Ethylene oxide gas 20% Carbon dioxide 80% Temperature : 104 to 140 F Humidity : 40 to 60% RH EO density : 500 to 600 mg/liter Action time : 4 hours Degassing method : Aeration Shelf condition : By aerator, 122 F Shelf time : 18 hours or more (48 hours or more at the room temperature and a general atmospheric pressure) This equipment is not waterproof. Don't sterilize the equipment and accessories in a way other than the above-mentioned condition, otherwise it may cause a failure in the equipment. 8.
