User Manual
Guidance and manufacturer's declaration – electromagnetic immunity
The RetinaStation is intended for use in the electromagnetic environment specified below. The customer or the
user of the RetinaStation should assure 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.
(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 RetinaStation is used exceeds the
applicable RF compliance level above, the RetinaStation should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
RetinaStation.
(b)
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
equipment should be used no closer to any
part of the RetinaStation, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1.2
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 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
(a)
survey, should be less than the
compliance level in each frequency
(b)
range.
