electromagnetic site survey, should be
less than the compliance level in each

NOTE: These guidelines may not apply in all situations. Electronmagnetic propogation is affected by absorption and reflections 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 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 Capnostream20P is used exceeds the applicable RF compliance level above, the
Capnostream20P should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the Capnostream20P.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
The monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the monitor can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the monitor as recommended below, according to the maximum output power of the communications
equipment.
