Guidance and manufacturer's declaration—electromagnetic immunity
The Model 7711 is intended for use in the electromagnetic environment specified below. The customer or the user
of the Model 7711 should assure that it is used in such an electromagnetic environment.

NOTE 1—At 26 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 Model 7711 is used exceeds the
applicable RF compliance level above, the Model 7711 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the scale.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Compliance Electromagnetic environment—
level guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the Model
005, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
