Directions for Use
Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and the ProXenon Headlight Camera System
The ProXenon Headlight Camera System is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or user of the ProXenon Headlight
Camera System can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
ProXenon Headlight Camera System 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.
