a Field strengths from xed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broad-
cast cannot be predicted theoretically with accuracy. To assess the electromagnetic environ-
ment due to xed RF transmitters, an electromagnetic site survey should be considered. If
the measured eld strength in the location in which the RS01 is used exceeds the applicable
RF compliance level above, the RS01 should be observed to verify normal operation. If ab-
normal performance is observed, additional measures may be necessary, such as reorienting
or relocating the RS01.
b Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF commu-
nications equipment and the RS01
The RS01 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the RS01 can help prevent
electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the RS01 as recom-
mended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended sep-
aration distance d in metres (m) can be estimated using the equation applicable to the fre-
quency 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 reection from structures, objects and people.
