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.
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 FT55 is used exceeds
the applicable RF compliance level above, the FT55 should be observed to verify normal operation. If abnormal performance is observed, additio-
nal measures may be necessary, such as re-orienting or relocating the FT55 .
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Recommended separation distances between portable and mobile RF communications equipment and the FT55
The FT55 series is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the FT55 series can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the FT55 series 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 determined 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.
