Guidance and manufacturer’s declaration – electromagnetic immunity
The Smartdop 45 is intended for use in the electromagnetic environment specified below. The customer or
the user of the Smartdop 45 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 Smartdop 45, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

P
is the maximum output power rating

the transmitter manufacturer and
d
is the
recommended separation distance in meters

Field strength from fixed RF transmitters, as
determined by an electromagnetic site
survey,

should be less than the
compliance level in each frequency range.

Interference may occur in the vicinity of the
equipment marked with the following
symbol:

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.
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 Smartdop 45 is used exceeds the applicable RF compliance level above, the
Smartdop 45 should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the Smartdop 45.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
