Recommended separation distances between RF wireless communications equipment
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 RF wireless
communications equipment and the device as recommended below, according to the maximum
output power of the communications equipment.
