RF emissions CISPR 11
Group 1
The Alvita Infrared Ear Thermometer uses RF energy only
for its internal function. Therefore, its RF emissions are very
low and are not likely to cause any interference in nearby
electronic equipment.
RF emissions CISPR 11
Class B
The Alvita Infrared Ear Thermometer is suitable for use in all
establishments, including domestic establishments and those
directly connected to the public low-voltage power supply
network that supplies buildings used for domestic purposes

Not applicable
Portable and mobile RF communication
equipment should be used no closer to
any part of the RA600 series, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance:
d = 1.2 √P
d = 1.2 √P 80MHz to 800MHz
d = 2.3 √P 800MHz to 2.5 GHz
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 metres (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic
site survey, (a) should be less then the
compliance level n each frequency range.
(b) interference may occur in the vicinity
of equipment marked with the following

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 structure, 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 FM transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which the Alvita Infrared Ear Thermometer is
used exceeds the applicable RF compliance level above, the Alvita Infrared Ear Thermometer should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the Alvita Infrared Ear Thermometer.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
