E Table 5: Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and the VP4726 and VP4726F Monitors
The ConMed Linvatec VP4726 and VP4726F Monitors are intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of the
VP4726 and VP4726F Monitors can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and
the VP4726 and VP4726F Monitors as recommended below, according to the maximum output

For transmitters rated at a maximum output power not listed above, the recommended separation
distances 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: E1) At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
Note 2: E2) These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
