Specific Notes for Measuring Ear Temperature
In ear mode, it is not uncommon for small variances in temperature
between each ear, so always take the temperature in the same ear.
Larger differences will be caused by positioning and technique, such as:
• The angle you are holding the thermometer.
• How far you have inserted the probe in to your ear.
• How much your hand may move.
This is because different positioning and technique will result in different
parts of the ear canal being measured. This is illustrated in Fig. 1-3.
Larger differences will also occur throughout the day as body
temperature fluctuates.
External factors also influence ear temperature, such as:
• Having been lying on an ear.
• One ear being covered.
• Being exposed to very hot or very cold
temperatures.
• Recently been bathing or swimming.
Obstructions in the ear like earwax will also
result in inaccurate or different readings as
they will interfere with the infrared heat being
measured by the eardrum and surrounding
tissues. This is illustrated in Fig. 4.
Also remember to:
• Correctly choose between ear and forehead modes,
as taking ear temperature when the thermometer is set
to forehead mode will give an inaccurate temperature
reading, and vice versa.
• Wait 10 seconds in-between each reading (to allow the probe to
re-acclimatise).
• Allow 30 minutes to elapse:
• Before taking ear or forehead temperature when coming
indoors from the cold or hot.
• If a cold-pack or hot-pack has been used.
• If the thermometer has been stored in a significantly cooler
or warmer environment.
Do not force the thermometer further in to the ear canal than feels
natural as it may cause injury or damage to the ear. Remove it
immediately if it causes pain or discomfort as this may also cause
injury or damage to the ear.
Do not insert the probe if suffering from an outer ear infection
(also known as otitis external or otitis media) or if the ear contains
medication, blood or any drainage as it may cause further damage
to the ear.
Do not insert the probe if the ear canal is wet (such as after
bathing or swimming) as it may cause injury or damage to the ear.
Specific Notes for Measuring Forehead Temperature
In forehead mode, it is not uncommon for variances in temperature
between different parts of the forehead. This is because forehead
temperature is affected by:
• Proximity of the temperature probe to blood veins, since an
area which has more veins close to the skin will be warmer than
an area that has bone under the skin.
• Environmental factors such as exposure to heat or cold.
For example, sitting next to a hot radiator or cold air
conditioning unit will directly affect forehead temperature, and
can even ensure that the temperature on one side of the head
is different to the other.
So every time you place the probe on your forehead, it is likely to
be in a different part of your head. This is why our thermometer
can take forehead temperature by scanning the probe from one
temple to the other, as this measures the highest temperature
across the whole forehead. See “Measuring Forehead Temperature”
for full instructions.
Next Reading Countdown
In-between each repeated forehead (or ear) reading,
pressing the ‘On/Temp’ button within 10 seconds of
the previous reading will result in a countdown from
10 appearing on the LED screen (to allow the probe
to re-acclimatise before you take the next reading).
The device automatically prevents you from taking
the next reading during this 10 seconds (see Fig 5),
after which the thermometer is ready to take another
reading.
General Warnings
Keep the thermometer out of children’s reach to ensure they
do not inflict damage on themselves by forcibly inserting the
thermometer too far in to their own ear.
Immediately consult a doctor if your child accidentally swallows
a battery.
Avoid knocking, shaking, dropping or stepping on the thermometer.
In such an event, carefully inspect the device for signs of damage
and immediately return to Brother Max for repair if you suspect
any faults.
Do not use a mobile or cordless phone near the thermometer.
Do not disassemble, repair, or modify the thermometer.
Do not use this thermometer other than for measuring ear or
forehead temperature.
Do not expose the thermometer to direct sunlight.
Store in a clean dry place.
Storage limits -20oC to 55oC with 95% maximum humidity.
