User Manual for Handheld Pulse Oximeter
50
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, and electromagnetic site
survey should be considered. If the measured field strength in the
location in which The Oximeter is used exceeds the applicable RF
compliance level above, The Oximeter should be observed to verify
normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating The
Oximeter.
b: Over the frequency range 150 kHz to 80 MHz, field strengths should
be less than 3V/m.
Table 4
Recommended separation distances between portable and mobile
RF communication the equipment
The Oximeter is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the
user of The Oximeter can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Oximeter as
recommended below, according to the maximum output power of the
communications equipment.
