Recommended separation distances between portable and mobile RF communications equipment and the Neptune 2 ULTRA Rover
The Neptune 2 ULTRA Rovers, REF 0702-001-000 and REF 0702-002-000, are intended for use in the electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the Neptune 2 ULTRA Rover can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Neptune 2 ULTRA Rover 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 meters (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.
