Appendix B – Electromagnetic Compatibility (EMC): Electromagnetic Immunity
Electromagnetic Immunity
Guidance and manufacturer’s declaration – electromagnetic immunity
The GE T2100 Treadmill is intended for use in the electromagnetic environment specified below. The customer or user of the
GE T2100 Treadmill should assure that it is used in such an environment.

Electromagnetic Environment – Guidance
Portable and mobile RF communications equipment should
be used on closer to any part of the [equipment or system]
,
including cables, than the recommended separation distance
calculated fro the equation applicable to the frequency of the
transmitter.

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 fixed RF transmitters, as determined by
an electromagnetic site survey
a
, should be less than the
compliance level in each frequency range.
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 reflection from structures, objects, and
people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile 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, and electromagnetic site survey should be considered. If the measured field strength in the location in which
the
GE T2100 Treadmill
is used exceeds the applicable RF compliance level above, the
GE T2100 Treadmill
should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the
GE T2100 Treadmill
.
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
