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 broadcastcannot 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 CMS50D1 Pulse Oximeter is used exceeds the applicable RF compliance level above, the CMS50D1
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 CMS50D1 Pulse Oximeter.

Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3V/m.

The CMS50D1 Pulse Oximeter is intended for use in the electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the CMS50D1 Pulse Oximeter can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the CMS50D1 Pulse Oximeter 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 distanced in
meters (m) can be estimated 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 80MHz and 800MHz, the separation distance for 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.
