Advanced Bionics Naida CI Q70 Instructions D'emploi page 24

Note 1: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.
a. Essential performance of the Naída 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 electro-
magnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered.
If the measured field strength in the location in which the
Naída CI is used exceeds the applicable RF compliance
level above, the Naída 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.
