Recommended separation distances between portable and mobile RF
communications equipment and the device
These devices are intended for use in an environment in which radiated RF disturbances are
controlled. The customer or the user of the device can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications
equipment(transmitters) and the device as recommended below, according to the maximum
output power of thecommunications equipment
