13. ELECTROMAGNETIC IMMUNITY
Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The OxyVet IV Oxygen Concentrator is intended for use in the electromagnetic environment specifi ed below. The customer
or the user of the OxyVet IV Oxygen Concentrator should assure that it is used in such an environment.

and d is the recommended separation

should be less than the
compliance level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic is affected by absorption and refl ection from
structures, objects and people.
a
Field strengths from fi xed transmitters, such as base stations for radio (cellular / cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fi xed RF transmitters, an electromagnetic site survey should be
considered. If the measured fi eld strength in the location in which the OxyVet IV Oxygen Concentrator is used exceeds
the applicable RF compliance level above, the OxyVet IV Oxygen Concentrator should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
the OxyVet IV Oxygen Concentrator.
b
Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.
