communication equipment and P290 device –for the P290 device
Recommended separation distances between portable and mobile RF communications equipment
and the
P290
The P290 device is designed for use in an electromagnetic environment in which interference due
to radiated RF is monitored. The customer or user of the P290 device can contribute to the
prevention of electromagnetic interference by keeping the P290 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.
