COMMENT 1 At 80 MHz and 800 MHz, the higher value shall apply.
This guidance may not apply in all situations. Electromagnetic propagation is affected by absorption and

reflection from structures, objects and people.
a The field strength of fixed transmitters such as base stations for wireless telephones and mobile land radio
services, amateur radio stations, AM and FM radio and television transmitters cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed HF transmitters, an electromagnetic site survey
should be considered. If the field strength measured at the location of the PRODUCT exceeds the compliance level
indicated above, the PRODUCT should be monitored for its normal operation at each place of use. If abnormal
performance characteristics are observed, additional measures may be necessary such as reorienting or relocating
the PRODUCT.
b In excess of the frequency range 150 kHz to 80 MHz, the field strength should be less than 3 V/m.
Recommended separation distances between portable and mobile HF communications equipment and the PRODUCT
The PRODUCT is intended for operation in an electromagnetic environment in which HF radiated disturbances are
monitored. The customer or user of the PRODUCT can help prevent electromagnetic interferences by maintaining
minimum distances between portable and mobile HF communications equipment (transmitters) and the PRODUCT as
recommended below, according to the maximum output power of the communications equipment.

For transmitters whose maximum output power is not listed in the table above, the distance can be determined using
the equation specified in the respective column, where P is the maximum output power of the transmitter in watts (W)
according to the transmitter manufacturer's specification.
COMMENT 1 An additional factor of 10/3 has been used to determine the recommended separation distance of
transmitters in the frequency range of 80 MHz to 2.7 GHz in order to reduce the likelihood that a
mobile/portable communication device placed inadvertently in the patient area will result in
interference.
COMMENT 2 This guidance may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
