EMC Tables
Guidance and manufacturer’s declaration – electromagnetic immunity
The product is intended for use in the electromagne c environment specified below. The customer or the user of the product should
assure that it is used in such an environment.

Portable and mobile RF communica ons equipment should be
used no closer to any part of the product, including cables,
than the recommended separa on distance calculated from
the equa on applicable to the frequency of the transmi er.
Recommended separa on distance
where P is the maximum output power ra ng of the
transmi er in wa s (W) according to the transmi er
manufacturer and d is the recommended separa on Distance
in meters (m).
Field strengths from fixed RF transmi ers, as determined by
an electromagne c 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:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situa ons. Electromagne c propaga on is affected by absorp on and reflec on from
structures, objects and people.
a. Field strengths from fixed transmi ers, such as base sta ons for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and
FM radio broadcast and TV broadcast cannot be predicted theore cally with accuracy. To assess the electromagne c environment due to fixed RF
transmi ers, an electromagne c site survey should be considered. If the measured field strength in the loca on in which the product is used exceeds
the applicable RF compliance level above, the product should be observed to verify normal opera on. If abnormal performance is observed, addi onal
measures may be necessary, such as re-orien ng or reloca ng the product.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
