Important Safety Information
Read this section thoroughly before using the product. Please ensure you observe
the safety instructions to avoid accidents, injury and damage.
Intended Purpose
• This product is intended for the measurement of human body temperature only. It is
designed for private use.
• The use of temperature readings for self-diagnosis is dangerous. Consult with a
doctor for the interpretation of results. Self-diagnosis may lead to the worsening
of medical conditions.

sensory or mental abilities or lacking experience and/or knowledge, unless they are
supervised by a person responsible for their safety or have received and understand the
instructions/ safety warnings for use of the product from this person in advance.
Safety Warnings
• KEEP BATTERIES OUT OF REACH OF CHILDREN
– Swallowing may lead to serious injury in as little as 2 hours or death,
due to chemical burns and potential perforation of the oesophagus.
– If you suspect your child has swallowed or inserted a button battery
immediately call the 24-hour Poisons Information Centre on
13 11 26 (Australia) or 0800 764 766 (New Zealand) for fast, expert advice.
– Examine devices and make sure the battery compartment is correctly secured,
e.g. that the screw or other mechanical fastener is tightened.

Package Contents
• 1 x Thermometer
• 1 x Protective Cover
• 1 x Battery (installed in product)
• 1 x Instruction Manual & Warranty Information
Digital Thermometer Components
Before using the Digital Thermometer
• Check the product is intact.
DO NOT
use if broken.
• Read the instruction manual thoroughly before taking the measurement.
• Allow product to rest for at least 30 minutes at room temperature (5˚C – 32˚C).
• The user must remain in a stable environment for at least 5 minutes prior to taking a
reading.
• Test the user’s temperature when they are well so there is a comparison when they
are unwell.
• Temperature readings are affected by many factors including physical exertion, the
drinking of hot or cold beverages before measurement, as well as measuring technique.
• Avoid using the product during or within 30 minutes after exercise; a shower, bath or
sauna; using a cold compress; heavy alcohol consumption; smoking and food or drink
intake.
• Underarms must be clean and free of sweat, deodorant and scars, etc. for underarm use.
• Always make sure the thermometric sensor is clean before each use.
• When measuring the temperature of an infant, note that infant body temperature is
generally higher than adult body temperature and easily affected by external factors.
For example, body temperature tends to increase after nursing or crying. Therefore, it is
recommended to take measurements when the infant is calm.
Using the Digital Thermometer
The use of temperature readings for self-diagnosis is dangerous. Consult with a doctor for
the interpretation of results. Self-diagnosis may lead to the worsening of medical conditions.

Taking a Temperature Measurement
Note:
The ambient temperature for use must be between 5-32°C. This product is a
maximum thermometer, i.e. the displayed temperature can increase slightly if measurement
continues after the beep. Holding the product too long may cause a higher ambient
temperature reading of the probe. This could make the body temperature measurement
lower than usual.
Before using, please disinfect the thermometric tip (refer to Cleaning section).
1. To turn on, press the button
next to the screen; a short
beep will sound, indicating that
the product is operational.
2. At the same time the product runs a
self-check test, during which all the digital
segments appear on the screen.
3. The memory will show the last reading
on the screen for 2 seconds.
4. A default value of
37.0°C
or
98.6°F
will display
for 2 seconds
(WDT101/WDT202 only)
.
5.
When the letters
Lo
or
L
and a “flashing”
°
C
or
°
F
display, the product is now ready for use.
6. Refer to
Methods of measuring temperature
section for placement instructions.
7. Keep the user still during the measurement.
8. During the measurement, the °
C
or °
F
symbol “flashes” and a temperature will be
displayed that will continue to change until a constant temperature is reached.
9. The temperature value is considered constant when the temperature rises less than
0.1°C within 16 seconds
(WDT101)
/ 8 seconds
(WDT202)
/ 4 seconds
(WDT303)
.
10. As soon as the constant temperature value is reached, a beep will sound multiple
times [10 times
(WDT101 and WDT202)
/ 12 times
(WDT303)
] and the °
C
or °
F
symbol
will stop flashing.
11. Once the beeping has stopped the measurement is completed. Remove the product
from the measurement site.
12. The highest temperature measured appears on the screen.
13. Turn the product off by pressing the button.
14. Although the product will turn off automatically, to conserve battery it is recommended
to turn the product off manually after each reading.
15. The reading will automatically be stored in the memory.
Note:
If choosing to take a second measurement, wait 60 seconds for the product to reset
before restarting the product.
Memory Function
• The last measured temperature will display on the screen for approximately 2 seconds
after the self-check when the product is turned on.
• WDT101/WDT202 models:
The reading will be over-written after the screen displays the
default value of 37.0°C.
• WDT303 model:
The reading will only be over-written when a new temperature value
is recorded.
Methods of Measuring Temperature
Note:
Measurement accuracy cannot be assured when the method used to measure the
temperature is incorrect. If multiple measurements are taken over a period of time, it is
important to use the same method of measurement each time so the results are comparable,
i.e. do not interchange between oral, rectal or underarm measurements. If taking multiple
measurements within a short period of time, allow the thermometer to return to room
temperature prior to taking each measurement.

• To ensure that reading is as accurate as possible, place the thermometric sensor to the left or
right of the underneath/root of the tongue. Ensure the screen faces upwards.
• The thermometric sensor must have constant contact with the tissue during the reading and be
placed under the tongue in one of the two heat pockets at the back. Press the tongue down to
hold the product in place.
• Keep the mouth closed during the reading and breathe evenly through the nose, while holding
onto the product to keep it from moving during measurement.
• There are different heat zones in the mouth. As a general rule, the oral temperature is 0.3°C to
0.8°C lower than the rectal temperature.
