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-X2705MD/X2700MD is used exceeds
the applicable RF compliance level above, the LMD-X2705MD/X2700MD should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the LMD-X2705MD/X2700MD.
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 6.795 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
The LMD-X2705MD/X2700MD is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the LMD-X2705MD/X2700MD can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the LMD-X2705MD/X2700MD as recommended below, according to the maximum
output power of the communications equipment.

For transmitters rated a maximum output power not listed above, the recommended separation distance in meters (m)
can be estimated using the equation applicable to the frequency of the transmitter, where
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.
