Note 1: At 80 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.

environment – guidance
In order to prevent electromag-
netic interference portable and
mobile RF communications
equipment should be used no
closer to any part of the
SmartLite Focus , including
® ®
cables, than the recommended
separation distance calculated
from the equation applicable
to the frequency of the trans-
mitter.
Recommended minimum
separation distance:
d = 1* √P for
150 kHz - 80 MHz
d = 2* √P for
80 MHz - 2.7 GHz
where P is the maximum out-
put power rating of the trans-
mitter in watts (W) according
to the transmitter manufacturer
and d is the recommended
separation distance in me-
ters (m).
Field strengths from fixed RF
transmitters, as determined
by an electro-magnetic site
survey (a), should be less than
the compliance level in each
frequency range (b).
Interference may occur in the
