Guidance and manufacturer 's declaration-electromagnetic immunity
The infrared thermometer is intended for use in the electromagnetic environment specified below. The customer or
the user of the infrared thermometer should assure that it is used in such an environment.

NOTE 1 At 90MHz and 800MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflec-
tion from structures, objects and people.

N/A
Mains power quality should be that of a typical commer-
cial or hospital environment. If the user of the infrared
thermometer requires continued operation during power
mains interruptions, it is recommended
that the infrared thermometer be powered from an unin-
terrupted power supply
or a battery

Electromagnetic environment-guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the infrared thermometer including
cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmit-
ter.
Recommended separation distance
d=1.2 P
d=1.2 P 80MHz to 800MHz
d=2.3 P 800MHz to 2.5MHz
Here 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 strengths form fixed RF transmitters,
as determined by an electromagnetic site survey, should be less
than the compliance b level in each frequency range. Interfer-
ence may occur in the vicinity of equipment
marked with the following symbol:
