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.
Field strengths from fixed transmitters such as base stations for radio (cellular/cordless) telephones and
a
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 Tango+ is used exceeds the applicable RF compliance level above, the Tango+ should be observed
to verify normal operation. If abnormal performance is observed additional measures may be necessary
such as reorienting or relocating the Tango+.
Over the frequency range 150kHz to 80 MHz, field strengths should be less than [V1] V/m.

Portable and mobile RF communications
equipment should be used no closer
to any part of the Tango+, 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, should be less than the
a
compliance level in each frequency.
