The Empi Phoenix is intended for use in the electromagnetic environment specified below. The customer or the user of the
Empi Phoenix should assure that it is used in such an environment.

NOTE 1 At 80 MHz and at 800 MHz ,the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
Field strengths from fixed 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 fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the Empi Phoenix device is used exceeds the applicable RF compliance
level above, the Empi Phoenix device should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the Empi Phoenix device.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m.
