8.4 portable and mobile RF communications equipment and the 4-Wheel Folding Scooter
Recommended separation distances between
portable and mobile RF communications equipment and the 4-Wheel Folding Scooter
The 4-Wheel Folding Scooter is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the 4-Wheel Folding Scooter can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the 4-Wheel Folding Scooter 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
distanced 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 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
