Guidance and manufacturer’s declaration – electromagnetic immunity
The Filac 3000 Electronic Thermometer is intended for use in the electromagnetic environment specified below. The customer or the
user of the Filac 3000 Electronic Thermometer 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 Filac 3000 Electronic
Thermometer, including 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 (

) according to the transmitter
manufacturer and d is the recommended separation distance
in meters (

).
Field strengths 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 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 Filac 3000 Electronic Thermometer is used exceeds the applicable RF compliance level above, the Filac 3000
Electronic Thermometer should be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as re-orienting or relocating the Filac 3000 Electronic Thermometer.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
