•
Electrosurgical units (ESUs) and other devices intentionally introduce radio
frequency electromagnetic fields or currents into patients. Because imaging
ultrasound frequencies are coincidentally in the radio frequency range,
ultrasound transducer circuits are susceptible to radio frequency
interference. While an ESU is in use, severe noise interferes with the black-
and-white image and completely obliterates the color image.
•
The sing cables, transducers, and accessories other than those specified for
use with the system may result in increased emissions from, or decreased
immunity of, the system.
•
Use of the system in the presence of an electromagnetic field can cause
momentary degradation of the ultrasound image. When interference is
present or intermittent, use caution when continuing to use the system. If
interference occurs often, review the environment in which the system is
being used to identify possible sources of radiated emissions. These
emissions could be from other electrical devices used within the same room
or an adjacent room. Communication devices such as cellular phones and
pagers can cause these emissions. The existence of radio, TV, or microwave
transmission equipment located nearby can cause emissions. In cases
where EMI is causing disturbance, it may be necessary to relocate your
system.
Battery Safety
Lithium-ion batteries are also used in medical diagnostic equipment as portable
diagnostic equipment; so, cautions indicated information to a user should pay
more attention.
Please be sure to take to comply with the specifications and the
following precautions to use with batteries, did not follow the specifications for
the operation caused any accidents, ASUSwill not accept any responsibility.
Most all instructions for battery using devices give the advice to not let a battery
for long periods of unused because can leak and cause damage to electronics; if
unused the equipment LU700 over one week, it should be charged with the
charging power supply of medical products comply with IEC 60601-1 for two
MOPP insulation system. The charging power supply should be checked or
replaced regularly.
•
Do Not charge the battery near a fire or heater.
•
If the battery leaks or emits an odor, turn-off the equipment
and contact
with local agent.
•
If the battery will remain unused for over a month, keep it between-20°C (-
4°F) and 20°C (68°F)
•
Do Not disassemble the device by yourself. The lithium battery may
explode due to a short circuit. Again, if user finds any abnormal behavior
of device LU700 Series, please turn-off the equipment and contact with
Leltek's local agent.
