3 Electromagnetic Compatibility (EMC) Information customer or the user of the AVIVA FX Power Wheelchair can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the AVIVA FX Power Wheelchair as recommended below, according to the maximum output power of the communications equipment. Rated maximum output power of transmitter W Separation distance according to frequency of transmitter m 150 kHz to 80 MHz 26 MHz to 800 MHz 800 MHz to 2,5 GHz 0,01 0.167 m 0.0175 m 0.035 m 0,1 0.53 m 0.055 m 0.11 m 1 1.67 m 0.175 m 0.35 m 10 5.3 m 0.55 m 1.1 m 100 16.7 m 1.75 m 3.5 m For transmitters rated at a maximum output power not listed above, the recommended separation distance din metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where Pis the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer. NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies. NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. 60101916-A 21

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in metres (m) can be estimated
using the equation
applicable to the frequency of the transmitter, where
P
is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
NOTE 1
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
