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 electromagnetic site survey should be considered. If the measured field strength in
the location in which the LMD-XH550N is used exceeds the applicable RF compliance level above, the
LMD-XH550N should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the LMD-XH550N.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
c The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to
6.7
95 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
Recommended separation distances between portable and mobile RF communications equipment
and
the LMD-XH550N
The LMD-XH550N is intended for use in an electromagnetic environment in which radiated RF
di
sturbances are controlled. The customer or the user of the LMD-XH550N can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the LMD-XH550N as recommended below, according to
the maximum output power of the communications equipment.

For transmitters rated a maximum output power n
ot listed above, the recommended separation
distance
d
in meters (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
a
bsorption and reflection from structures, objects and people.
