RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF
COMMUNICATIONS EQUIPMENT AND THE OPERATING TABLE VACB-3006B
Operating Table VACB-3006B is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of Operating Table VACB-
3006B can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and Operating Table VACB-
3006B 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 metres (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.
