b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [Vi] V/m.
Recommended separation distances between portable and mobile RF
communications
equipment and the device.
The device is intended for use in an electromagnetic 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 the communications equipment.
