RF emissions
CISPR 11 Group 1 The Vivo 3 use RF energy only for its
internal function. Therefore, its RF emis-
sions are very low and are not likely to
cause any interference in nearby electronic
equipment.
RF emissions
CISPR 11 Class B The Vivo 3 are suitable for use in all
establishments, including domestic estab-
lishments and those directly connected to
the public low-voltage power supply net-
work that supplies buildings used for
domestic purposes.

9.7.3 Recommended separation distances between portable and mobile RF
communications equipment and the Vivo 3
The Vivo 3 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Vivo 3 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Vivo 3 as recommended
below, according to the maximum output power of the communications equipment.

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.
Notes
•
At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
