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 Radar Plus is used exceeds
the applicable RF compliance level above, the model Endo Radar Plus 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 Radar Plus.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3V/m.

RF communications equipment and the model Endo Radar Plus
Recommended separation distances between
portable and mobile RF communications equipment and the model
Endo Radar Plus
The model Endo Radar Plus is intended for use in electromagnetic environment
in which radiated RF disturbances is controlled. The customer or the user of
the model Endo Radar Plus can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the model Endo Radar Plus
as recommended below, according to the maximum output power of the
communications equipment.
