GUIDANCE AND DECLARATION - ELECTROMAGNETIC IMMUNITY
The
Trio
is intended for use in the electromagnetic environment specified below. The customer or the
user of the
Trio
should assure that it is used in such an environment.

ENVIRONMENT - GUIDANCE
Portable and mobile RF communications
equipment should be used no closer to
any part of the
Trio
, 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 recommended
separation distance in meters (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:
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.
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 theo-
retically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electro-
magnetic site survey should be considered. If the measured field strength in the location in which the Trio is
used exceeds the applicable RF compliance level above, the Trio should be observed to verify normal opera-
tion. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the Trio.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
