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

Portable and mobile RF
communications equipment should
be used no closer than 30cm (12
inches) to any part of Triangle,
including cables specified by the
manufacturer.
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey
(1)
,
should be less than the compliance
level in each frequency range.
(2)
Interference may occur in the
vicinity of equipment marked with
the following symbol:
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to
2,7 GHz
3 V/m
80 MHz to 2,7
GHz
Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
Note:
(1)
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile, 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 measured
field strength in the location Triangle is used in exceeds the applicable RF compliance level
above, Triangle should be observed to verify its normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating Triangle
(2)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
