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.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/
cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an elec-
tromagnetic site survey should be considered. If the measured field strength in
the location in which the Prolife PS1 Standard is used exceeds the applicable RF
compliance level above, the Prolife PS1 Standard should be observed to verify
normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the Prolife PS1 Standard.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.
Recommended separation distance between portable and mobile RF commu-
nications equipment and the Prolife PS1 Standard
The Prolife PS1 Standard is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of
the Prolife PS1 Standard help prevent electromagnetic interference by main-
taining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Prolife PS1 Standard 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 recom-
mended separation distance d minimetres (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: these guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
