should be used no closer to any
part of the models D600, D600
LED, including cables, than
the recommended separation
distance calculated from the
equation applicable to the
frequency 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 be less than
the compliance level in each
frequency range.
b
Interference may occur In the
vicinity of equipment marked
with the following symbol:
NOTE I At 80 MHz end 800 MHz. the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic
propagation is a󰀨ected by absorption and reection from structures, objects and
people.
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 broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to
xed RF transmitters, an electromagnetic site survey should be considered. If the
measured eld strength in the location in which the models D600, D600 LED are
used exceeds the applicable RF compliance level above, the model D600, D600
LED should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as reorienting or
relocating the models D600, D600 LED.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3V/m.
