Invacare® Perfecto₂™ V Oxygen Concentrator
measured field strength in the location in which the Device is used exceeds the applicable RF compliance level above, the Device
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the Device.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
b
At 80 MHz and 800 MHz, the higher frequency range applies.
Recommended separation distances between portable and mobile RF communications equipment and the Device
The Device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the Device can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Device as recommended below, according to the
maximum output power of the communications equipment
