1) Measuring ear temperature
Remove the forehead measurement
cap from the product to enter the
ear mode.
Press the
[ M ]
button to turn on the product.
The LCD is lit for 2 seconds, and then the
last measurement value is displayed for 2
seconds. After a “beep” sound, the product
is ready to take ear temperature. Insert
the temperature probe into the ear canal
gently, and press the [ ] button once. A
“beep” sound indicates the measurement
is completed, with the measurement result
displayed on the screen.
If the body temperature is less than 37.5°C,
the screen has green backlight; if the body
temperature is equal to or greater than
37.5°C but less than 38.0 °C, the screen has
orange backlight; if the body temperature is
equal to or greater than 38.0°C, the screen
has red backlight, as shown in the figure
below:
Note:
To take the temperature of infants under one
year old, gently pull the auricle backward
and downward and hold there to expose
the tympanic membrane to the temperature
probe.
To take the temperature of children above
one year old or the adults, gently pull the
auricle backward and upward and hold there
to straighten the ear canal, so as to expose
the tympanic membrane to the temperature
probe.

Recommended separation
distance:
d =1.2√ P
d =1.2√ P 80 MHz~800 MHz
d =2.3√ P 800 MHz~2.5 GHz
Where P is the maximum

according to the transmitter
manufacturer and
d is the recommended
separation distance in
meters (m).
Field strengths from
xed RF transmitters,
as determined by an
electromagnetic site
surveya should be less than
the compliance level in each
frequency rangeb.
Interference may occur in
the vicinity of equipment
marked with the following
symbol.
Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and reection
from structures, objects and people.
A Field strengths from xed 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 xed RF transmitters, an electromagnetic site
survey should be considered. If the measured eld strength in the
location in which the product is used exceeds the applicable RF
compliance level above, the product should be observed to verify
normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the
product.
B Over the frequency range 150 kHz to 80 MHz, eld strengths should
be less than 3 V/m.

Separation distance between this product and portable/mobile RF
communication equipment
This product is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or
the user of the product can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile
RF communication equipment (transmitters) and the product as
recommended below, according to the maximum output power of the
communications equipment.
