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.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Table 4
Recommended separation distances between portable and mobile RF communications
equipment and the DirectLink
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.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
