1. Safety precautions
• Structure of the power supply equipment
• Inclination of the device (whether the ground is flat or slanted)
• Whether the device is turned on and whether it is moving
If this device is affected, there is a possibility of abnormal movement. It may begin moving uncontrollably or stop
suddenly. Strong EMI or RFI can damage the control system.
1.1.2. Important information regarding Electro Magnetic Compatibility (EMC)

Cable Max. cable length,
Shielded/unshielded
Number Cabl e classifi cation
AC Power Line 1.5 m Unshielded 1 Set AC Power
DC Power Line 1.2 m Unshielded 1 Set DC Power
This electrical medical equipment needs special precautions regarding EMC and 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:
• The equipment with no ESSENTIAL PERFORMANCE is intended for use in the home healthcare environment.
• 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.
• 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 Model F, including cables specified
by the manufacturer. Otherwise, degradation of the performance of this equipment could result.
• WARNING: If the use location is near (e.g. less than 1.5 km from) AM, FM or TV broadcast antennas, before using
this equipment, it should be observed to verify that it is operating normally to assure that the equipment remains
safe with regard to electromagnetic disturbances throughout the expected service life.
• When the AC input voltage is interrupted, the equipment will stop battery charging and if the power supply
restored, it could be recovered automatically, 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.
During all immunity tests, a digital tachometer was used to monitor the rotating speed of wheel and a clamp meter
was used to monitor the output current of battery charger to verify the performance of EUT.
