Chapter 1 Warranty and Service
Standard Service
EDAN provides a one-year-warranty for the warranted products (accessories are included). The
warranty period begins on the date the products are shipped to customers. If a customer promptly

Chapter 2 Introduction
The service provider must read and understand all the information presented in this manual
before installing or servicing a unit.
Typical users of the basic service manual:
Service personnel (installation, maintenance, etc.);
Hospital service personnel;
Contractors.
The service provider should fully read and understand the user manual before operating the DUS
60. It should also be kept near the unit for quick reference.
2.1. Safety Considerations
2.1.1. Introduction
WARNING
1. This equipment is not intended for treatment.
2. Do not pull the I / F connector in or out while the module is operating.
3. The startup voltage of backlight is approximately 1000 Volts. It may cause electrical
shock while assembling with inverter. Do not disassemble the module or insert
anything into the backlight unit.
4. If the liquid crystal material leaks from the panel, it should be kept away from the
eyes or mouth. In case of contact with hands, skin or clothes, it has to be washed
away thoroughly with soap.
CAUTION
1. The pictures and interfaces in this manual are for reference only.
2. Do not apply rough force such as bending or twisting to the LCD module during
assembly.
3. Assembling or installing the LCD module into user’s system can only be performed in
clean working areas. The dust and oil may cause electrical short or worsen the
polarizer.
4. It’s not permitted to have pressure or impulse on the module; otherwise, the LCD
panel and backlight will be damaged.
5. Do not disassemble the LCD module.
The following safety precautions must be observed during all phases of operation, service and
repair of this equipment. Failure to comply with these precautions or with specific warnings
elsewhere in this manual, violates the safety standards of the design, manufacture and intended
use of the equipment.
The standard three-pin socket should be used for power supply, and its protection terminal should
be connected with to the grounding wire. If there is no protection terminal available in the socket
or not connected with to the grounding wire of power supply, you are advised to use a spare

grounding wire provided by our company for the connection between the protection grounding
column and the earth.
NOTE:
1. This equipment is not intended for home use.
2. Follow the experienced technician’s instruction when connecting the earth wire.
2.1.2. Human Safety
Servicing should be performed by authorized personnel only.
Only personnel who have participated in the DUS 60 training are authorized to service the
equipment.
2.1.3. Mechanical Safety
WARNING
1. Take care when moving the unit, or when it is raised for repair or moved along any
incline, as the trolley may become unstable which could cause the unit to tip over (with
trolley).
2. Ultrasound probes are highly sensitive medical instruments that can easily be
damaged by improper handling. Take care when handling and protect them from
damage when not in use. Do not use a damaged or defective probe. Failure to follow
these precautions can result in serious injuries and equipment damage.
3. Never use a probe that has fallen to the floor.
NOTE:
Special care should be taken when transporting the unit in a vehicle:
1. Secure the unit in an upright position.
2. Lock the wheels (brake).
3. Do not use the control panel as an anchor point.
4. Place the probes in their carrying case.
2.1.4. Electrical Safety
To minimize shock hazard, the equipment chassis must be connected to an electrical ground.
The system is equipped with a three-conductor AC power cord. This must be plugged into an
approved electrical outlet with safety ground if an extension cord is used with the system. Make
sure that the total current rating of the system does not exceed the extension cord rating.
The power outlet used for this device should not be shared with other types of device.
Both the system power cord and the power connector meet international electrical standards.
