Guidance and manufacturer's declaration—electromagnetic immunity
The NVM5
is intended for use in the electromagnetic environment specified below. The customer or the user of the
®
NVM5 should assure that it is used in such an environment.
Immunity test
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 Vrms
IEC 61000-4-3 80 kHz to 2.5 MHz
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, 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 equipment used exceeds the applicable RF compliance
level above, the equipment should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the equipment.
b Over the frequency range 150 KHz to 80 MHz field strengths should be less than 3 V/m.
c The Impedance Meter Accessory has a compliance level of 2 V/m in the range 80 MHz to 2.5 GHz.

Electromagnetic environment—
Portable and mobile RF communications
equipment should be used no closer to any of the
NVM5 including cables, than the recommended
separation distance calculated from the equation
applicable 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,
should be less than the compliance level in each
frequency range.
Interference may occur in the vicinity of equipment
