The TheraKair Visio MRS is intended for use in the electromagnetic environment specified below. The
customer or the end user of the TheraKair Visio MRS should ensure that it is used in such an environment.
Immunity Test
Conducted RF
EN / IEC 61000-4-6
Radiated RF
EN / IEC 61000-4-3
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: The guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from objects,
structures and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular / cordless) telephones and land mobile radios, amateur radio,
a
AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment
due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the
TheraKair Visio MRS is used exceeds the applicable RF compliance level above, the TheraKair Visio MRS should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the TheraKair Visio
MRS.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
