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 MEDICAL SCALE M-110 is used
exceeds the applicable RF compliance level above, the MEDICAL SCALE M-110 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 M-110.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be les than 3 V/m.
