Guidance and Manufacturer’s Declarations (cont.)
Electromagnetic Immunity (cont.)
The Smartdop ®
30EX is intended for use in the electromagnetic environment specified below. The user of
the Smartdop ®
30EX should assure that it is used in such an environment.
Immunity test IEC60601 test level Compliance level Electromagnetic environment

Portable and mobile RF communications
equipment should be used no closer to
any part of the Smartdop ® 30EX, includ
ing 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 strength 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 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 fro
m 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 access 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
®
30EX is used exceeds the
applicable RF compliance level above, the Smartdop
®
30EX should be observed to verify normal operation. If abnor
-
mal performance is observed, additional measures may be necessary, such as reorienting or relocating the Smartdop
®
30EX
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m
