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.
4) Be sure to confirm the equipment, options and peripheral devices are washed, disinfected or sterilized appropriately when you take them back from customer site.
5) In case the equipment radiates X-ray, pay attention to the circumference and take care not exposed X-ray indiscreetly when the equipment is radiating. You must put a film badge for monitoring the personal exposure at proper position when you do the repair work.
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.

1-8 Precautions to ensure safety of software

OS (Operating System, such as Windows) operation is allowed Service Engineer who has taken appropriate training. Illegal change on OS or our program files, Illegal copy of file/folder/partition which NOT instructed, are prohibited.
Computer controlled medical equipment that involves starting up an operating system from an internal storage drive could become infected with computer viruses.
Such equipment is usually infected via peripheral storage, media or connections to a network. Examples detailing route of infection
A) Infections caused during upgrades or maintenance by service engineer.
An infected USB memory device was connected. An infected floppy disk was inserted. A virus-infected USB hard disk drive was connected to remove data.
B) Infections caused by copying/backing up the preset data or stored images
An infected USB memory device was connected. An infected floppy disk was inserted. A virus-infected USB hard disk drive was connected to remove data.
1) Scan all media for viruses before connecting them to or inserting them in the equipment.
2) When an infection is detected, investigate the route of infection and its scope before removing the virus.
3) Any connections to a network should as far as possible be routed via a firewall.
4) Software, files or services other than those designated by us must not be installed on or uninstalled from the equipment. Nor must files other than those specified by us be modified or edited.
5) DO NOT connect the internal storage device (hard disk, CF card and so on) to your PC. It may cause the computer virus infection to the machine.

Chapter 1 Introduction

1-9 Precautions for software safety of maintenance tools

These maintenance tools refer to the laptop computers and auxiliary storage devices that service engineers carry around. (Any computer used for creating CD-Rs for installing upgrades is also regarded as a maintenance tool.) Thus maintenance tools will include laptop computers, floppy diskettes, USB memory devices, external hard disks, CD-Rs, etc.
1) Perform a virus scan of any tool that will be used to ensure that they are not infected by computer viruses.
Regularly perform virus scans of maintenance tools.
2) In unavoidable cases when for some reason safety cannot be confirmed, or when an unknown computer or memory device is connected, be sure to perform a virus check after use.
3) Update with the most recent virus pattern data prior to performing a virus scan.
4) If a virus scan does not remove the cause for anxiety, use another virus scanner to check.

1-10 Precautions regarding handling of patient data

Extreme care must be taken to ensure that data (image data, patient database, DICOM communication log files) that has been saved to another media during equipment repair and may include patient data is guarded against leakage, loss and theft. Delete any data that is no longer needed.
1) Work involving use of patient data should be performed in a room that can be locked to prevent leakage, loss or theft of such data.
2) Such data must be stored in a locked shelf or similar container.
3) If no lockable shelves are available, encrypt the files to reduce possible harm in the event of theft, leakage or loss.

1-11 Preparation to be made before visit customer

1) When called by a customer on the telephone, note the followings:
Name of equipmentSerial number of equipmentName of hospitalTelephone numberName of person in chargeDetail of trouble symptom as far as possibleState of connection to optional devices
2) Go over the “Technical Bulletin” and “Technical Notes” to see whether the complained trou ble can be mended by means of regular repairing method.
1 - 5
MN2-2075 Rev.0 Chapter 1 Introduction

1-12 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 structure of the equipment such as Software Version.
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.

1-13 Handling of PCB

It is our 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.
Do not give excessively large shocks to the PCB.
Very thin wiring patterns require extreme care in handling of 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.
Reuse of chip devices (including resistors, capacitors, diodes, etc.) is strictly inhibited.
CAUTION 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.

1-14 WEEE Directive and RoHS Directive
