Recommended Separation Distances Between Portable and Mobile RF Communications Equipment
The WiSe™ 26" HDTV Surgical Display is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The user of the WiSe™ 26" HDTV Surgical Display
can help prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the WiSe™ 26" HDTV Surgical Display
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 MHz 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.
