Anyone using the equipment should be taught to recognize the ESD symbol and to
take the necessary precautionary procedures.
WARNING The ultrasound scanner is not designed to be used in potentially explosive
environments. It should not be operated in the presence of flammable liquids or gases,
or in oxygen-enriched atmospheres.
There is a possible explosion hazard if the scanner is used in the presence of
flammable anesthetic. The scanner should be placed at least 25cm (10 inches) from
the patient.
The ultrasound scanner contains a lithium battery. Never remove or replace this
battery. The lithium battery must not be removed except by a B-K Medical service
representative.
WARNING Do not plug the scanner into an ordinary power strip. If the ground
connection fails, this is dangerous because
•
the total leakage current for all the connected equipment can exceed the limits
specified in EN/IEC 60601-1 [2].
•
the impedance of the ground connection will probably also exceed the limits
specified in EN/IEC 60601-1.
WARNING When the equipment is used with 230V (and you believe the leakage
current would be within the UL limit if you were using 120V), power to the equipment
must come from an installation or supply unit with a center-tapped, 240V single-phase
circuit. This will make sure that chassis leakage current during single fault condition
fulfills the requirements specified in UL2601-1 [4] (limit of 300µA). If power is not
supplied in the way specified, the leakage current can be as high as 500µA, the limit
specified in EN/IEC 60601-1. [2]
WARNING Never remove the cover to get access to the inside of the scanner. You
risk electrical shock if you do so. Do not allow anyone but qualified service personnel
to service the scanner.
WARNING Do not touch pins in connectors that have this symbol. Do not connect
anything to them unless you follow these ESD (electrostatic discharge) precautionary
procedures:
•
Discharge your body to ground before you touch the pins with your hand or a tool.
For example, touch an unpainted metal part of the scanner cover.
•
You can use a wrist strap connected to the additional protective ground or potential
equalization terminal on the scanner if that is more convenient.
