Recommended separation distances between portable and mobile RF communications equipment and the
telescopic pillar CPMT (Table 6 – IEC 60601-1-2)
The telescopic pillar CPMT is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or user of the telescopic pillar CPMT can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the telescopic pillar
CPMT as recommended below, according to the maximum output power of the communications equipment.
