Separation Distance - GE T2100 Service Manual

Guidance and manufacturer's declaration – electromagnetic immunity (cont'd.)
Immunity Test
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.

Separation Distance

This table provides the recommended separation distances between portable and
mobile RF communications equipment and the T2100 Treadmill.

Compliance
Test level
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 T2100 is used
exceeds the applicable RF compliance level above, the T2100 should
be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting
or relocating the T2100.
Over the frequency range 150 KHz to 80 MHz, field strengths should
be less than V1 V/m.
