Radiated RF IEC 61000- 3 V/m 80MHz to 2,7 GHz
4-3
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 MEDICAL SCALE MBF-6000/6010 is used exceeds the applicable RF compliance level above, the
MEDICAL SCALE MBF-6000/6010 should be observed to verify normal operation. If abnormal performance is observed, additional
measures my be necessary, such as re-orienting or relocating the MEDICAL SCALE MBF-6000/6010.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be les than 3 V/m.
Recommended separation distance between portable and mobile RF communications equipment and the MEDICAL SCALE
The MEDICAL SCALE MBF-6000/6010 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the MEDICAL SCALE MBF-6000/6010 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the MEDICAL SCALE
MBF-6000/6010 as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be
estimated using 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.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
