Observe the following safety precautions.
CAUTION:
Malfunctions due to radio waves
(1) This system may malfunction due to electromagnetic
influence from electric scalpels, high-frequency therapy
equipment, or other devices that generate high
frequencies.
(2) The use of radio-wave-emitting devices near this unit may
interfere with its operation. Devices that generate radio
waves, such as cellular phones, transceivers, and radio-
controlled toys, must not be brought into the room where
this unit is installed and must never be used near the unit.
(3) If a device that generates radio waves is brought into the
room where this unit is installed, instruct the user to turn
OFF the power of the device immediately. This is
necessary to ensure proper operation of the system.
magnetic fields (near transformers, for example). Such fields may
adversely affect the monitor.
(such as medical telemeters and cordless telephones). Doing so may
cause the system to malfunction or to adversely affect such devices.
or stack such devices on each other. If doing so is unavoidable,
confirm that the system operates normally at its usual operating
location.
1. When a fetus is to be exposed to ultrasound, set the
acoustic power to as low a level as possible.
2. The FDA allows ultrasound equipment to output acoustic
power level TRACK3, which is higher than TRACK1,
provided that MI/TI values are displayed on the system.
This means that users now have a higher degree of
responsibility for safety. Users are thus required to
understand the bioeffects of ultrasound and their causes,
and to only then increase diagnostic capabilities by
increasing MI/TI.
Refer to section 24 "Using MI/TI" for details.
