PROPRIETARY AND CONFIDENTIAL DRAFT 19-DEC-11
NOTE: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
NOTE: Electromagnetic immunity was examined under normal operation at the time of
testing. Normal operation was the essential performance used. Electromagnetic immunity
was verified at settings of 4 for intensity and 12 Hz for frequency.
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 can not be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters,
the electromagnetic site used should be considered. If the measured field strength
in the location in which the Model 205 is used is more than the applicable RF
compliance level above, the Model 205 should be monitored to make sure it
operates correctly. If it operates incorrectly, additional measures may be
necessary, such as a change in the Model 205’s position or location.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3 V/m.
