Guidance and manufacturers declaration – electromagnetic immunity.
The Primo Interferential 960/Multidyne 970 is intended for use in the electromagnetic
environment specified below. The customer or user of the Primo Interferential 960/Multidyne
970 should assure that it is used in such an environment.

Interference may occur in the vicinity of
equipment marked with the following symbol:
NOTE 1 At 80MHz and 800MHz 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 Primo Interferential 960/Multidyne 970
is used exceeds the applicable RF compliance level above, the Primo Interferential
960/Multidyne 970 should be observed to verify normal operation. If abnormal performance is
observed additional measures may be necessary, such as re-orienting or relocating the Primo
Interferential 960/Multidyne 970.
b
Over the frequency range 10kHz to 80Mhz, field strengths should be less than 3 V/m.
