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 Endo 1 is used
exceeds the applicable RF compliance level above, the model Endo 1 should
be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the
model Endo 1.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3V/m.
17.5 Recommended separation distances between portable and mobile RF
communications equipment and the model Endo 1
Recommended separation distances between portable and mobile RF
communications equipment and the model Endo 1
The model Endo 1 is intended for use in electromagnetic environment in
which radiated RF disturbances is controlled. The customer or the user of the
model Endo 1 can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications
equipment (transmitters) and the model Endo 1 is recommended below,
according to the maximum output power of the communications equipment.
