2-1 Precautions Against Electrical Hazards to Serviceman When disassembling the equipment after checking it for a trouble symptom, give care to the following: 1)
Be sure to unplug the equipment before disassembly.
2)
Be sure to turn off the main switch on the equipment when removing electrical parts such as PCBs, probe, and cable.
3)
Safety alert symbols
4)
The indication
used on this equipment and in this service manual have the following meaning
“ Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. ”
“ A caution message is inserted here. ”
2-2 Precautions Against Mechanical Hazards to Serviceman When disassembling the equipment, give care to the following to protect serviceman from hazards: 1)
Keep the working environment neat.
2)
Wear working gloves to protect your hands from getting injured by burrs on the unit and casing.
3)
Use only proper tools suited to work being made.
4)
Be sure to observe the specified disassembly procedure shown in SECTION 9.
5)
Take sufficient care not to damage component with undue load.
2-3 Precautions Against Germ Hazards to Serviceman 1)
When it is necessary to touch the equipment, options and/or other peripheral devices at a customer who uses intracorporeal (transesophageal, transurethral, transvaginal, transrectal) probes that need sterilization, take special care to protect your hands against germs, irrespective of the usage of the equipment: whether it is used in the operation room or not.
2)
Service tools are subject to germ pollution in hospitals and, therefore, need periodical sterilization.
3)
Be careful not to directly touch anything assumable to have germ pollution. If necessary, ask the customer for effective protection against germs.

PRECAUTIONS
2-4 Precautions for Keeping Electrical Safety 1)
Be sure to ground the equipment securely.
2)
Perfectness in grounding, screw tightening, and cover installation is essential. Negligence of it could cause a possibility of leakage current from outer fitting which may lead to serious damage to a patient being diagnosed.
2-5 Precautions for Keeping Mechanical Safety Take care to the following to prevent the equipment from being damaged or broken during disassembly and reassembly work. 1)
Be sure to observe the specified disassembly procedure.
2)
Take care not to damage component parts by undue load.
3)
Take care not to damage component parts by undue load.
4)
Use only the specified screws and nuts. Using any other screws and/or nuts would affect not only mechanical performance, but also electrical performance of the equipment.
2-6 Precautions for Keeping Chemicals Safety Whenever grease, oil or other chemicals is used for maintenance service, options and/or peripheral devices, be sure to clean the equipment and/or devices after service work.

SECTION 2
MN2-2008 PRECAUTIONS
2-8 Care to be Taken in the Field 1)
Check for trouble symptoms.
2)
Check for connection to optional devices and other peripheral devices.
3)
Record the contents of the battery backup memory.
4)
After working, restore the equipment according to the above mentioned contents of memory if necessary.
5)
After completion of work, put back the peripheral devices to the original condition.
2-9 Precaution for Monitor repairing 1)
Subjecting the unit to strong shocks may result in damage to the CRT or malfunction, therefore care must be taken when transporting or installing the unit. z DANGER z High voltages are present inside the display chassis. Only experienced technicians should touch internal parts. z DANGER z The electric charge has remained in CRT after the power switch is turned off. Because the high voltage is usually used for CRT.
So make the electric
charge escape with a grounding stick which is connected to the ground of the chassis and through the resistance for high voltage (Approx. 1MΩ) before removing the anode cap. Some electric charge remains in CRT after escaping with a grounding stick. Do not touch the metallic part of anode cap with bare hands, when detaching the anode cap directly. 2)
CRT with the deflecting yoke is already adjusted to the best condition. deflecting yoke and the magnet of the neck part.
Do not touch the
3)
Be sure to detach the metallic goods such as a wrist watch from your body before doing the repair work.
To prevent the secondary damage and the electrical shock, the matters above should be taken into careful consideration.

PRECAUTIONS
Handling of S.M.D. PCBs
It is an Aloka's policy that neither repair nor modification of PCBs used for S.M.D. is made in the field as a rule because of the following reasons: [REMARKS]
PCB does not need repairing or modifying in the field as a rule.
When handling a PCB, do not touch the IC unless it is necessary. IC soiled with worker’s hands may cause corrosion. Additionally, foreign particles such as fine solder dust could be the cause of short-circuited IC lead wires whose pitch is smaller than that of the traditional ones. z CAUTION z When handling a PCB, avoid touching the IC and connector pins on the devices to prevent ESD (Electro Static Discharge) damage. A service person should preferably wear an ESD wrist strap correctly grounded when handling a PCB. Do not give excessively large shocks to the PCB. When replacing the ROM (Read Only Memory) on the PCB, attempting to force the ROM into its socket would cause the PCB to be subjected to an undue force, and the following faults may : 1)
Damage to PCB intermediate-layer patterns,
2)
Peeling of chip devices (resistor, capacitor, diode, etc.),
3)
Damage to a junction between electrode and internal element of chip devices,
4)
Peeling of patterns (especially those for mounting the parts) together with chip devices since those patterns are rather fragile compared with PCBs used before now, and
5)
Damage to parts on the reverse side in the case of PCBs of both-side mounting type.
Also, a PCB mounted improperly or a warped PCB mounted as it is may cause the chip devices to come off and the fine patterns to be cut. Additionally, reuse of chip devices (including resistors, capacitors, diodes, etc.) is strictly inhibited because of the following reason: Since the chip devices are lacking in lead wires, such as those found in the traditional component parts, heat given to the PCB will be directly conducted to the inside of chip devices. As a result, a thermal stress will occur due to a difference in thermal expansion coefficient between each chip device and PCB, giving rise of the possibility of cracks inside of or on the surface of chip devices or the possibility of thermal breaking (internal burning).
Very thin wiring patterns require extreme care in handling of the PCB. Be sure to observe the precautions mentioned above also to prevent the secondary accidents.
