Portable and mobile RF communications
equipment should be used no closer to
any part of the Model LRK-7000, including
cables, than the recommended separation
distance calculated from 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 and d is the
recommended separation distance in
meters(m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey, a should

Interference may occur in the
vicinity of equipment marked with
the following symbol:
NOTE 1 At 80 MHz and 800 MHz, 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.
