a. Field strengths from fi xed 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 fi xed RF transmitters, an electromagnetic site survey should be considered.
If the measured fi eld strength in the location in which the system is used exceeds the applicable RF compliance level
above, the PSPIX system should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the PSPIX system.
b. Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communication equipment and the PSPIX
system
The PSPIX system is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the PSPIX system can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the PSPIX system
as recommended below, according to the maximum output power of the communications equipment.
Nominal Maximal Output of
the device in W

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
refl ection from structures, objects and people.
