Recommended separation distances between portable and mobile RF communications
equipment and the S/5 Light Monitor.
Recommended separation distances between portable and mobile RF communications
The S/5 Light Monitor is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the S/5 Light Monitor can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the S/5 Light Monitor 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.
