Guidance and manufacturer's declaration ± electromagnetic immunity
The Focus is intended for use in the electromagnetic environment specified below. The customer or the user of the Focus should assure that it is used
in such an electromagnetic environment.

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 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 Focus is used exceeds the applicable RF compliance level above, the Focus should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the Focus.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Portable and mobile RF communications equipment should be used no closer
3 Vrms
to any part of the Focus including cables, than the recommended separation
distance calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distance

3 V/m
D= 1.2 x √P from 80MHz to 800MHz
D= 2.3 x √P from 800MHz to 2.5GHz
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).
