Recommended Separation Distance Between Portable and Mobile RF Communications
Equipment and the oyager Duo for Equipment and Systems that are not
Life-Supporting
Recommended separation distances between portable and mobile RF communications equipment and the Voyager
Duo.
The Voyager Duo is intended for use in electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Voyager Duo can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communication equipment (transmitters) and the
Voyager Duo 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.
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.
