Recommended Separation Distance - WALLACH ZOOMSTAR User Manual

Recommended Separation Distance

This section discusses the Recommended Separation Distance between portable and mobile RF
communications equipment and the Wallach Colposcopes.
The Wallach Colposcopes are intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Wallach Colposcopes
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Wallach Colposcopes
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 rating of the transmitter in watts (W) according to the transmitter manufacturer.
For the Wallach Colposcopes

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.
