a. Essential performance of the Sky CI per IEC 60601
requirements is defined as auditory stimulation within safe
amplitudes.
b. 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 Sky CI is used exceeds the
applicable RF compliance level above, the Sky CI should
be observed to verify normal operation.
c. Over the frequency range 150 kHz to 80 MHz, field
strengths should be less than 3 V/m.

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