[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 and TV broadcasters
cannot
be accurately
predicted theoretically. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be conducted. If the measured field strength in
the location in which the CLEO Patient Monitor is used exceeds the applicable RF compliance
level, verify that the CLEO Patient Monitor works normally. If you observed abnormal performance,
you may need to reorient or relocating the CLEO Patient Monitor.
b. Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between portable and mobile RF communications
equipment and the CLEO Patient Monitor
The CLEO Patient Monitor is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled.
The customer or the user of the CLEO Patient Monitor can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the CLEO Patient Monitor 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 formula
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.
