Guidance Regarding Electromagnetic Environment
RF emissions CISPR 11
Group 1
The Empi Active uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to cause
any interference in nearby electronic equipment
RF emissions CISPR 11
Class B
The Empi Active is suitable for use in all establishments, including
domestic establishments and those directly connected to the public
low-voltage power supply network that supplies buildings used for
domestic purposes.

Electromagnetic Environment - Guidance
Portable and mobile RF communications equipment should
be used no closer to any part of the Empi Active device,
including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of
the transmitter.

Where P is the maximum output power rating of the transmit-
ter in watts (W) according to the transmitter manufacturer and
d is the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey
a
, 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
propagation is affected by absorption and reflection from structures,
objects and people.
a
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 Active device is used exceeds the applicable RF compliance
level above, the Empi Active 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 Active device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
