Electromagnetic immunity
Portable and mobile RF communications
equipment should be used no closer to any part
of the Connex Central Station, including cables,
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distances:
d = 1.2
d = 2
Conducted RF
IEC 61000-4-6
150KHz to 80MHz
：
3Vrms
6Vrms (in ISM and
amateur radio bands)
80% Am at 1kHz
Not applicable
Radiated RF
IEC 61000-4-3 10V/m 10V/m
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 MHz to 2.7 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 meters
(m). 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 Welch Allyn CareTemp™ Touch Free Thermometer
is used exceeds the applicable RF compliance level above, the Welch Allyn CareTemp™ Touch Free Thermometer should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the Connex Central Station.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
