Guidance and manufacturer's Deceleration – Electromagnetic Immunity
The Prima OPH is intended for use in the electromagnetic environment specified below. The
customer or user of the Prima OPH should ensure that it is used in such an environment.
Immunity Test IEC 60601 Test Level
Conducted RF
3 vrms
IEC 61000-4-6
150kHz - 80MHz
Radiated RF
80MHz to 2.5 GHz

@ 3V/m
Note 1: At 80 MHz to 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 access 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 may be necessary, such as re-orienting or relocating the ME Equipment or ME System.
*Over the frequency range 150kHz to 80 MHz, field strengths should be less than [V1] V/m.

Electromagnetic environment
Portable and mobile Rf communications
equipment should be used no closer to any
part of the Prima OPH, including cables, than
the recommended separation distance calcu-
lated from the equation applicable to the
frequency of the transmitter.
Recommended Separation Distance:
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 recom-
mended separation distance in meters (m).
Field strengths from fixed Rf 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
