Guidance and manufacturer’s declaration - electromagnetic immunity
The UP-DR80MD is intended for use in the electromagnetic environment specified below. The customer or the user of the
UP-DR80MD should assure that it is used in such as environment.
Immunity test
IEC 60601 test

Portable and mobile RF communications equipment should
be used no closer to any part of the UP-DR80MD, including
cables, than the recommended separation distance
calculated from the equation appliance to the frequency of
the transmitter.
Recommended separation distance
d = 1.2 √P
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.5 GHz
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 following symbol:
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.
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 UP-DR80MD is used exceeds the applicable RF
compliance level above, the UP-DR80MD should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the UP-DR80MD.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
