SPECIFICATIONS AND PERFORMANCE
Guidance and manufacturer's declaration - electromagnetic immunity
The SL-D7/SL-D8Z is intended for use in the electromagnetic environment specified below. The
customer or the user of the SL-D7/SL-D8Z should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the SL-D7/SL-D8Z, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

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 compli-
ance level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following sym-
bol:
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.
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 consid-
ered. If the measured field strength in the location in which the SL-D7/SL-D8Z is used
exceeds the applicable RF compliance level above, the SL-D7/SL-D8Z should be observed
to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the SL-D7/SL-D8Z.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
