Recommended separation distances between portable and mobile
RF communications equipment and Treatlite
Treatlite is intended for use in an electromagnetic environment in which radiated RF disturbances are con-
trolled. The customer or the user of Treatlite can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and Treatlite 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 transmit- ter 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. Electro- magnetic propagation is affected by
absorption and reflection from structures, objects and people.
