ecommended eparation
d :
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
evice
or the user of this device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and this device as recommended below, according to the maximum output power of the
communications equipment.
