Recommended separation distances between portable and mobile RF communications
equipment and the
P280
The P280 device is designed for use in an electromagnetic environment in which interference
due to radiated RF is monitored. The customer or user of the P280 device can contribute to
the prevention of electromagnetic interference by keeping the P280 device at the
recommended distances from portable and mobile RF equipment (transmitters) as shown
below, according to the maximum power output of the communication equipment.

For transmitters with a maximum transmitting power not given above, the recommended
separation distance in meters (m) can be estimated by using the equation applied to the
transmitter frequency, where P is the maximum transmitting power of the transmitter in Watts
(W), according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the highest frequency range
applies.
NOTE 2: These directives cannot be applied to every situation. The propagation of
electromagnetic waves is affected by absorption and reflection due to structures, objects and
persons.
