Recommended separation distances between portable and mobile RF telecommunications
equipment and VISULAS YAG III
The VISULAS YAG III is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or user of the VISULAS YAG III can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the VISULAS YAG III 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 80 and 800 MHz, 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.
