Guidance and Manufacturer's Declaration – Electromagnetic Immunity
The Phoroptor VRx is intended for use in the electromagnetic environment specified below. The
customer or user of the Phoroptor VRx should ensure that it is used in such an environment.
Immunity
Test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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.
* 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. The measured field strength in the location in which the ME Equipment or
ME System should be observed to verify normal operation. If abnormal performance is observed, additional
measures might be necessary, such as re-orienting or relocating the ME Equipment or ME System.
* Over the frequency range 150 kHz to 80 MHz, field strengths should be less then [V1] V/m.

Test Level
3 Vrms (V1)=3V/m
150 kHz to 80
MHz
80 MHz to 2.5 (E1)=3V/m
GHz @ 3V/m
Level Environment
Portable and mobile RF communications
equipment should be no closer to any part
of the Phoroptor VRx, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended Separation Distance:
d=(3.5/V1)(Sqrt P)
d=(3.5/V1)(Sqrt P)
80 to 800 MHz
d=(7/E1)(Sqrt P)
800 MHz to 2.5 GHz
Where P is the max 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 transmitters,
as determined by an electromagnetic site
survey, should be less than the compliance
levels in each frequency range.
Interference may occur in the vicinity of
equipment containing a transmitter.
