The CUSA EXcel is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The 5
Customer or the user of the CUSA EXcel can help prevent electromagnetic interferences by maintaining a minimum distance between 8
portable and mobile RF communications equipment (transmitters) and the CUSA EXcel as recommended below, according to the の
maximum output power of the communications equipment. ©

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be
estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At a80MHz and 800MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
