Environment - Guidance
Portable and mobile RF
communications equipment
should be used no closer to
any part of the model REF
130-002, including cables,
than the recommended
separation distance
calculated from the equation
applicable to the frequency
of the transmitter.
d = [ ]√P 80 MHz to
800 MHz
d = [ ] √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 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.

Interference may occur in the
vicinity of equipment marked

NOTE 1: U
T
is the a.c. mains voltage prior to application of the test level.
NOTE 2: At 80MHz and 800MHz, the higher frequency range applies.
NOTE 3: 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 model
130-001 is to be used exceeds the applicable RF compliance
level above, the model
130-001 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the model
130-001.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.
