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 ApexPilot G1 is used
exceeds the applicable RF compliance level above, the model ApexPilot G1
should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as reorienting or
relocating the model ApexPilot G1.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3V/m.

communications equipment and the model ApexPilot G1
Recommended separation distances between
portable and mobile RF communications equipment and the model
ApexPilot G1
The model ApexPilot G1 is intended for use in electromagnetic environment in
which radiated RF disturbances is controlled. The customer or the user of the
model ApexPilot G1 can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment
(transmitters) and the model ApexPilot G1 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) accordable to the transmitter
manufacturer.
NOTE I
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.
