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 DirectLink is used exceeds the applicable RF compliance level above,
the DirectLink should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the DirectLink.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Portable and mobile RF communications
equipment should be used no closer to any part
of the DirectLink, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
d = 1.2 √ P 80 MHz to 800 MHz
d = 1.2 √ P 80 MHz to 800 MHz
d = 2.3 √ 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,
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:
Recommended separation distances between portable and mobile RF communications
The DirectLink is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the DirectLink can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the DirectLink as recommended below, according to
the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using 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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
