9.7 RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE
RF COMMUNICATIONS EQUIPMENT AND HAUSTED ESC2EYEST PROCEDURE CHAIR
1
The Hausted ESC2EYEST Procedure Chair is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Hausted ESC2EYEST Procedure Chair
can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Hausted ESC2EYEST Procedure Chair 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 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.
