Guidance and Manufacturer's Declaration–Electromagnetic Immunity
The eQuinox is intended for use in the electromagnetic environment specified below. The customer or the user of the eQuinox should
assure that it is used in such an environment.
Immunity test
IEC 60601 test level
Conducted RF
3 Vrms
IEC 61000-4-6
150 kHz to 80 MHz
Radiated RF
3 V/m
IEC 61000-4-3
80 MHz to 2,5 GHz
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 struc-
tures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
a
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromag-
netic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the eQuinox is used exceeds the applicable RF compliance level above, the eQuinox should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the eQuinox.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment – guidance
Portable and mobile RF communications equip-
ment should be used no closer to any part of the
eQuinox, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.

where P is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended separation distance in metres (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.
