survey should be considered. If the measured eld strength in the location in which
the [KD-558] is used exceeds the applicable RF compliance level above, the [KD-558]
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the [KD-558].
b Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than
3V/m.

For ME EQUIPMENT and ME SYSTEMS that are not
LIFE-SUPPORTING
Recommended separation distances between portable
and mobile RF communications equipment and the [KD-558]
The [KD-558] is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the [KD-558] can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the [KD-558]
as recommended below, according to the maximum output power
of the communications equipment.
Rated maximum Separation distance according to frequency of transmitter m

100 12 12 23
For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (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 reection from structures, objects and people.
