recommended separation distance in meters
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in
each frequency range.
Interference may occur in the vicinity of
equipment marked with the following symbol:
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 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 scale is used exceeds the application RF compliance level
above, the scale 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.
Recommended separation distance between portable and mobile RF communications equipment and the M-65x.
This scale is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the scale can help prevent electromagnetic interference by maintaining a minimum distance between
