measured outside of the
measurement range (0.0 to
100.0 °C).
Review the instructions and
re-start the measurement
procedure.
Low or no power.
Replace with new batteries.
Measured temperature
below the measurement
range (below 32.0 °C).

measurement. Make sure the
distance from forehead is not
greater than 7cm (2”), and that
the forehead is clear.
Measured temperature
above the measurement
range (above 43.0 °C).
Review instructions and repeat
measurement. Consult with a

The IR42 is intended for use in the electromagnetic environment (for home and professional healthcare) specified below.
The customer or the user of the IR42 should assure that it is used in such an environment.
The IR42 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.
The IR42 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.

Recommended separation distance between
portable and mobile RF communications equipment and the IR42
The IR42 is intended for use in an electromagnetic environment (for home and professional healthcare) in which radiated RF disturbances
are controlled. The customer or the user of the IR42 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the IR42 as recommended below, according to the
maximum output power of the communications equipment.
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be
estimated using 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.
NOTE1
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.

Test specifications for ENCLOSURE PORT IMMUNITY to RF wireless communications equipment
The IR42 is intended for use in the electromagnetic environment (for home and professional healthcare) specified below.
The customer or the user of the IR42 should assure that it is used in such an environment.
NOTE
If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna and the ME EQUIPMENT or
ME SYSTEM may be reduced to 1 m. The 1 m test distance is permitted by IEC 61000-4-3.
a) For some services, only the uplink frequencies are included.
b) The carrier shall be modulated using a 50 % duty cycle square wave signal.
c) As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does not represent actual
modulation, it would be worst case.
