Recommended separation distances between portable and mobile RF communication
equipment and analyzer
The analyzer is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled.The customer or the user of the devices can help prevent electromagnetic interference by
maintaining a
equipment(transmitters)and the analyzer as recommended below,according to the 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 80MHz 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.
A. From the date of purchase, the product will enjoy one-year free warranty with the
purchase invoice. During the warranty service, if you need to provide circuit diagram,
components, necessary materials and electrical circuit maintenance problems, please
