Electromagnetic environment – Guidance
Portable and mobile RF communications equipment should be used no
closer to any part of the Osia Sound Processor, including cables, than
the recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
IMMUNITY TEST: Conducted RF IEC 61000-4-6
COMPLIANCE LEVEL: 3 Vrms 0.15 to 80 MHz; 6 Vrms in ISM 0.15 to
80 MHz
Recommended separation distance d=1.2√P
IMMUNITY TEST: Radiated RF IEC 61000-4-3
COMPLIANCE LEVEL: 10 V/m 80 MHz to 2.7 GHz
d=0.35√P 80 MHz to 800 MHz
d=0.70√P 800 MHz to 2.7 GHz
where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer and d is the
recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey, should be less than the compliance level in
each frequency range.
Interference may occur in the vicinity of equipment marked
with the following symbol:
IMMUNITY TEST: Proximity fields from RF wireless communications
equipment IEC 61000-4-3
COMPLIANCE LEVEL: 385 MHz (27 V/m); 450, 810, 870, 930, 1720,
1845, 1970, 2450 MHz (28 V/m); 710, 745, 780, 5240, 5500, 5785 MHz
(9 V/m)
WARNING
Portable RF communications equipment (including peripherals
such as antenna cables and external antennas) should be used
no closer than 30 cm (12 in.) to any part of your Osia Sound
Processor, including cables specified by the manufacturer.
Otherwise, degradation of the performance of this equipment
could result.
WARNING
Use of accessories, transducers and cables other than those
specified or provided by Cochlear could result in increased
electromagnetic emissions or decreased electromagnetic
immunity of this equipment and result in improper operation.
