Important information regarding electromagnetic compatibility (EMC)
This electrical medical equipment needs special precautions regarding EMC and should be
put into service according to the EMC information provided in the user manual. The equipment
conforms to this IEC 60601-1-2:2014 standard for both immunity and emissions. Nevertheless,
special precautions need to be observed:
Warning:
The equipment is intended used in professional healthcare facility environment ex-
cept for near active HF SURGICAL EQUIPMENT and the RF shielded room of an ME SYSTEM
for magnetic resonance imaging, where the intensity of EM DISTURBANCES is high. Essential
Performance of the device includes supplying continuous sound output during a medical
evaluation equal to or below 92.1 dB.
Warning:
Use of this equipment 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.
Warning:
The 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.
Warning:
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 658,
including cables specified by the manufacturer. Otherwise, degradation of the performance of
this equipment could result.
Warning:
When the AC input voltage is interrupted, the equipment will shut down and if the
power supply restored, it should be recovered by operator manually. This degradation could be
accepted because it will not lead to unacceptable risks and it will not result in the loss of basic
safety or essential performance.
Warning:
Accessories and cables provided with this device have not been tested or verified
for use with other medical electrical equipment and should not be considered interchangeable.
