communications
equipment should be used no
closer to any part
of the medi pcs, including
cables, than the
recommended separation
distance calculated
from 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 and d is the
recommended separation
distance in meters (m). Field
strengths from fixed RF
transmitters, as determined
by an electromagnetic site
survey, a should be less
than the compliance level
in each frequency range. b
Interference may occur in the
vicinity of equipment marked
with the following symbol:
Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
NOTE 1 At 80 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.
The medi pcs is intended for use in the electromagnetic environment specified below. The
customer or the user of the medi pcs should assure that it is used in such an environment.
• 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 medi pcs is used exceeds the applicable RF
compliance level above, the medi pcs should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the medi pcs.
