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

Electromagnetic environment – guidance
Portable and mobile RF communications equipment
should be used no closer than 30cm (12 inches) to any
part of the Ultimate Contour, including cables. Otherwise,
degradation of the performance of this equipment could
result.

d = [7/E1] √ P 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 metres (m). Field strengths from fixed RF
transmitters, as determined by an electromagnetic site
survey a, should be less than the compliance level in
each frequency range b
Interference may occur in the vicinity
of equipment marked with the
following symbol:
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 Ultimate Contour is used exceeds the applicable RF compliance level above, the Ultimate
Contour should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Ultimate Contour.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
