3. Operation of system, in the case that the patient physiological
signal is lower than the minimum amplitude or value specified in
the product specifications, results may not be obtained (results
can be obtained when the HR is in the range of 30-250 bmp or
when the QRS wave amplitude is between 0.5-5 mV.)
4. Use of the system adjacent to or stacked with other equipment
should be avoided because it could result in improper operation.
If such use is necessary, this equipment and the other equipment
should be observed to verify that they are operating normally.
5. Use of accessories, transducers and cables other than those
specified or provided by the manufacturer of this equipment
could result in increased electromagnetic emissions or
decreased electromagnetic immunity of this equipment and
result in improper operation.
6. Portable RF communications equipment (including peripherals
such as antenna cables and external antennas) should be used
no closer than 30 cm (12 inches) to any part of the system,
including cables specified by the manufacturer. Otherwise,
degradation of the performance of this equipment could result.
7. The system should be away from RFID, MRI, diathermy, and
electrocautery testing, wireless power transfer, 5G cellular and
security equipment (such as electromagnetic anti-theft system
and metal detector). If the devices are near and are interfered by
the concealed and undiscovered RF transmitter (for example,
scanning mode changes or image disturbances affecting
diagnosis), the user should immediately take mitigation
measures, such as redirecting, repositioning or shielding the RF
transmitter.
