Recommended separation distances between

portable and mobile RF communications equipment and the PF LIGHT

The PF LIGHT is intended for use in an electromagnetic environment in which radiated RF disturbances

are controlled. The customer or the user of the PF LIGHT can help prevent electromagnetic interference by

maintaining a minimum distance between portable and mobile RF communications equipment

(transmitters) and the PF LIGHT 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 determined 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 The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz

to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.

NOTE 3 An additional factor of 10/3 is used In calculating the recommended separation distance for

transmitters In the ISM frequency bands between 150 kHz and 80 MHz and In the frequency range 80 MHz

to 2,5 GHz to decrease the likelihood that mobile/portable communications equipment could cause

interference If it is inadvertently brought into patient areas.

NOTE 4 These guidelines may not apply in all situations. Electromagnetic propagation is affected by

absorption and reflection from structures, objects and people.
