●
Ensure the potential-equalization lead wire is connected before inserting the
equipment power plug.
●
The AC power connector plug for the ultrasound system is a three-prong grounded
plug and should never be adapted to any two-prong outlet or by using an adapter.
The AC power connector plug should be plugged into a hospital-grade power outlet.
●
Select the qualified multi-socket outlet with protective grounding, and ensure its
maximum output power not exceed the required one of this system.
●
The multi-socket outlet can only be used to provide power to the recommended
peripheral devices of this system.
●
Do not place the multi-socket outlet on the floor.
●
Do not connect other devices to the multi-socket outlet; otherwise, the rated output
power may be exceeded and failure may be resulted.
●
The video printer should be connected to the specific interface using the cable
provided by the manufacturer; Otherwise, there is a danger of electric shock.
●
Accessory equipment connected to the analog and digital interfaces must be certified
according to the respective EN/IEC standards (for example, EN/IEC 60950 for data
processing equipment and EN/IEC 60601-1 for medical equipment). Furthermore,
all configurations shall comply with the system standards EN/IEC 60601-1-1.
●
In the environment that patient is 1.8 meters (6 feet) around, connect peripherals
to the auxiliary power outlet which is capable of isolation protection, or power the
peripherals by auxiliary output cable or isolation transformer complied with IEC
60601-1-1 or the power input of the same safety level.
●
Parts of non-medical electrical equipment in the patient environment that, after
removal of covers, connectors, etc., without the use of a tool, may be contacted
during the routine maintenance, calibration, etc. You should not touch the referred
parts and the patient simultaneously.
●
Do not use the probe other than those provided by the manufacturer. Otherwise, the
ultrasound system cannot be performed, and an accident such as a fire may result in
the worst case.
●
Only the peripherals and accessories provided or recommended by the manufacturer
can be used. Using other devices or accessories may degrade the system
performance and even cause an electrical shock.
●
Do not pour any fluid onto the ultrasound system surfaces, as fluid seepage into
the electrical circuitry may cause excessive leakage current or system failure. If
carelessly pour any water onto the system, immediately stop using the ultrasound
system and contact Service Representative immediately.
●
To avoid electrical shock and damage to the ultrasound system, power off and
unplug the system from the AC power outlet before cleaning.
●
To maintain the safety and functionality of the ultrasound system, maintenance must
be performed at least every 6 months. Electrical safety tests must also be performed
at regular intervals as specified by local safety regulations.
