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 CMS60D Pulse Oximeter is used exceeds the
applicable RF compliance level above, the CMS60D Pulse Oximeter
should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary,
such as reorienting or relocating the CMS60D Pulse Oximeter.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should
be less than 3 V/m.
Recommended separation distances between portable and mobile
RF communications equipment and the EQUIPMENT or SYSTEM –

Recommended separation distances between
portable and mobile RF communications equipment and the CMS60D
Pulse Oximeter.
The CMS60D Pulse Oximeter is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or the user of the CMS60D Pulse Oximeter can help prevent
electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment
(transmitters) and the CMS60D Pulse Oximeter as recommended
below, according to the maximum output power of the
communications equipment.
