Table 2.1: Table of Symbols
These symbols (icons) listed in table 2.1 are used with the equipment
and/or within this manual. They serve as warnings, or for marking con-
nections and etc.
2.3 Electrical Safety
• The equipment conforms with the following regulations for electrical
safety,
–IEC 60601-1: 1988+A1:1991+A2:1995, Medical Electrical Equip-
ment Part 1: General Requirements For Safety, Class I, BF, con-
tinuous operation
–IEC 60601-2-37: 2001 + A1:2004 + A2:2005, Medical Electri-
cal Equipment Part 2-37: Particular Requirements For The Safety
Of Ultrasonic Medical Diagnostic And Monitoring Equipment
• The equipment conforms with the following EMC/EMI standards:
IEC60601-1-2: 2001+A1: 2004, Class A (CE)
• Degrees of protection against harmful liquid: IPX0 for the S6 system
and IPX7 for the accompanying probes.
Please comply with the following rules for safety considerations:
• Properly grounding the system can prevent potential electric shock,
ensure that the three-conductor AC power cord equipped with the
system is plugged into an electrical outlet/receptacle marked with
hospital grade. The equipment has an extra grounding point (located
P/N: 4720-0034-01A
2-2

S6 Portable Digital Color Doppler Ultrasound System
Service Manual
at the lower rear panel). To avoid loss of image quality, it is compul-
sory to connect this point to ground (earth).
• Potentially hazardous electrical voltage exists inside the equipment.
Unauthorized personnel DONOT attempt to open the cover of the
equipment.
• The equipment must not be used in the presence of inflammable gases
(e.g. anesthetic gases and nitrous oxide) to avoid explosion hazard.
• Devices must be powered from a receptacle marked "hospital grade"
before being connected to the system directly. In case "hospital grade"
receptacles are not available, use isolation transformers instead.
Warning!
Electrostatic discharge (ESD) may cause electric shock or
damage the equipment. Observe the following precautions:
1. Prior to repairing or cleaning the equipment, ensure
that the system has been turned off and the power ca-
ble unplugged.
2. The equipment must be grounded correctly during op-
eration. Use anti-ESD spray on the ground if possible.
• The leakage current of the entire system including all auxiliary equip-
ments must not exceed the limit as stated in IEC 60601-1.
• The equipment may interfere with or be interfered by other high fre-
quency devices (e.g. medical lasers). Extra safety measures must be
taken if other HF devices have to be used nearby.
• Use the couplant shipped with the equipment or any other couplant
recommended by SonoScape. Use any unrecommended couplant
may damage the probe and void the warranty.
2.4 Mechanical Safety
1. Prior to using the equipment, place it horizontally and lock the wheels.
2. Take care when moving the equipment. Failure to follow the pre-
cautions listed below could result in injury, uncontrolled motion and
costly damage.
∗Take the following precautions before transporting the system:
1) Ensure that the system is powered off and with power cable un-
plugged.
P/N: 4720-0034-01A
2-3

S6 Portable Digital Color Doppler Ultrasound System
Service Manual
2) Disconnect all the probes from the system and place them in
their carrying case.
3) Ensure that all the peripherals and auxiliary devices have been
disconnected from the system.
4) If you are moving the docking cart together with the S6 system,
unlock the wheels.
5) Now you can hold the handle and push the system to the des-
tined place.
∗If the system is to be transported for long distance, take the fol-
lowing precautions as well:
6) It’s highly recommended to backup the critical data (e.g. patient
data and images) to a DVD/CD or hardcopy.
7) Ensure that the system is well prepared and packed in its original
packaging before transporting.
8) Place the system upwards, and ensure that it is firmly secured
while inside the vehicle during transport.
Warning!
Avoid collisions and excessive vibrations to prevent data loss
or system malfunction.
Never move the equipment which is still operating.
Environmental Conditions for Transportation:
Relative Humidity: 20% to 90%, no condensation
Temperature: -20°C to 55°C
Barometric Pressure: 700 to 1060hPa
2.5 Human Safety
Modern diagnostic ultrasound system has been proved to be safe for daily
diagnostic usage, however, only the well trained/educated medical person-
nel should operate the equipment. The ALARA (As Low As Reasonably
Achievable) principle must be observed. The following are some more de-
tailed guidelines on safety use of the equipment.
• Keep the power levels and the exposure time as low as possible, as
long as a satisfactory diagnosis has been achieved.
• Use the freeze function or move the probe away from the patient
while not scanning.
• Do not rest the transducer on the skin surface when not scanning.

• The imaging system of S6 is based on Doppler and Color Doppler
Imaging. The output power of the ultrasound is lower than the limits
as required by the standard IEC 60601-1.

Description of the System
3.1 Product Description
The S6 is a professional, general purpose portable color Doppler diagnostic
ultrasound system. It employs digital technology and fully exploits the
potential of integrated circuits. The software is based on Linux system,
which enhances the stability and efficiency while maintains the portability.
The user interface has been optimized for ease of use. The imaging system
can be adjusted during the scanning process; while for advanced users, the
system configurations can be changed quite intuitively.
A wide range of probes make the system suitable for many applications.
To keep the system up to date, the software updates are provided regularly.
To enhance the system performance even more, users may also take the
hardware upgrade service provided by SonoScape. There are a variety of
upgradeable options available.
