Table 7. Guidance and Manufacturer’s Declaration, Electromagnetic Immunity, for the
Tenex Health TX System.
The Tenex Health TX System is intended for use in the electromagnetic environment specied below. The customer
or the user of the Tenex Health TX System should assure that it is used in such an environment.

Portable and mobile RF Communications
equipment should be used no closer to any
part of the Tenex Health TX System, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of
the transmitter.
Recommended separation distance
d = 1.2 √ P
d = 1.2 √ P 80 mHz to 800 mHz
d = 1.2 √ P 800 mHz to 2.5 gHz
Where P is the maximum output power
rating of the transmitter in watts (W) according
to the transmitter manufacturer and d is the
recommended separation distance in
meters (m).
Field strengths from the xed 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
reection from structures, objects, and people.
a. Field strengths from 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 xed RF transmitters, an electromagnetic site
survey should be considered. If the measured eld strength in the location in which the Tenex Health TX System
is used exceeds the applicable RF Compliance level above, the Tenex Health TX System should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorientating or relocating the Tenex Health TX System.
b. Over the frequency range 150 kHz to 80 mHz, eld strengths should be less than 3 V(rms)/m.
