1 Second Infrared Ear Thermometer
Thank you for purchasing the BIOS Diagnostics 1 Second Ear Thermometer.
The BIOS Diagnostics 1 Second Ear Thermometer is a high quality product
incorporating the latest technology and tested in accordance with international
standards.
With its unique technology, this thermometer can provide safe, accurate and
reliable readings with each measurement on people over 2 years of age.
Features
Multiple Uses (Wide Range Measurement)
This thermometer oers a wide measurement range feature from 0°C to
100.0°C (32.0°F to 212.0°F), meaning the unit can be used as an ear
thermometer to measure body temperature or it can be used to measure
surface temperature of the following:
• Milk surface temperature in a baby’s bottle
• Surface temperature of a baby’s bath
• Ambient temperature
Measurement in 1 Second
The innovative infrared technology allows measurement of ear temperature in
only 1 second.
Multiple Reading Recall
Users will be able to recall the last 30 readings when entering the recall mode,
enabling ecient tracking of temperature variations.
Fever Alarm
10 short beeps and a red LCD backlight alerts the patient that he/she may
have a temperature above 37.4°C / 99.3°F.
Illuminated Probe
This thermometer includes a probe LED light which enables the user to nd
the correct ear position in the dark. The probe will illuminate for approximately
10 seconds when the thermometer is turned ON.
“Clean Me” Technology
After each temperature measurement “clean me” will ash on the LCD to
remind users to clean the probe. See Care and Cleaning section.

Accurate and Reliable
The unique probe assembly construction incorporates an advanced infrared
sensor, ensuring that each measurement is accurate and reliable.
Please read these instructions carefully before using this
thermometer and keep both in a safe place.
1. IMPORTANT SAFETY INSTRUCTIONS
This instrument may only be used for the purposes described in this booklet.
The manufacturer cannot be held liable for damage caused by incorrect
application.
Never immerse this instrument in water or other liquids. For cleaning
please follow the instructions in the «Care and Cleaning» section.
• Do not use the instrument if there are any signs of damage. Do not
attempt to repair the instrument.
• Earwax in the ear canal may cause a lower temperature reading,
therefore it is important to ensure the patient’s ear canal is clean.
• If the measurement result is not consistent with the patient’s nding or
suspiciously low, repeat the measurement every 15 minutes or double
check the result by another core body temperature measurement.
• This thermometer consists of high quality precision parts. Do not drop
this instrument. Protect it from severe impact and shock.
• Keep the thermometer away from direct exposure to the sun and keep it
in a dust-free dry area.
• If the instrument is not going to be used for a prolonged period the
battery should be removed.
WARNING:
• Use of this thermometer is not intended as a substitute for consultation
with your physician.
• Ensure that children do not use the instrument unsupervised; some parts
are small enough to be swallowed.
• It is not recommended to use infrared thermometers on children under 2
years of age.
• Infrared thermometers should not be used to manage important health
concerns, and therefore parents should not rely solely on temperature
readings to evaluate the status of your child’s health. If you have any
concerns, consult with your doctor.

3. HOW THIS THERMOMETER MEASURES
TEMPERATURE
This thermometer measures infrared energy radiated from the eardrum
and the surrounding tissue. This energy is collected through the lens and
converted to a temperature value. The measured reading obtained directly
from the eardrum (Tympanic Membrane) ensures the most accurate ear
temperature.
Measurements taken from the surrounding tissue of the ear canal generate
lower readings and may result in misdiagnosis of fever.
4. DIRECTIONS FOR USE
IMPORTANT: If using the thermometer for the rst
time, remove the plastic strip located in the battery
compartment.
1. Switch ON the thermometer by pressing the ON/OFF button, all segments
will be shown for 1 second. (Figure 1)

2. After one beep is heard and the °C / °F icon is ashing, the thermometer
is ready for measurement. Straighten the ear canal by gently pulling the
middle of the ear back and up.
3. Place the probe rmly into the ear canal, press the START button and
keep the probe in the ear until the thermometer beeps to signal the
completion of the measurement. The probe LED light will turn OFF once
the START button is pressed to take the measurement.
about 1 sec.
NOTE:
• Always insert the thermometer in the same ear with the same direction
and depth.
• Always clean the probe accordingly before and after each use. (See
Care and Cleaning Section).
• It is recommended that you measure the temperature 3 times in the
same ear. If the 3 measurements are dierent, select the highest one.
(Allow 30 seconds between each measurement).
• Before measurements, remain in a stable environment and avoid
exercise and bathing for 30 minutes.
• Readings from dierent measuring sites should not be compared as the
normal body temperature varies by measuring site and time of day, being
highest in the evening and lowest about one hour before waking up.
Normal body temperature ranges:
- Axillary: 34.7 – 37.3°C / 94.5 – 99.1°F
- Oral: 35.5 – 37.5°C / 95.9 – 99.5°F
- Rectal: 36.6 – 38.0°C / 97.9 – 100.4°F
- Ear: 35.4 – 37.4°C / 95.7 – 99.3°F
5. SETTING DATE AND TIME
1. Once a new battery is installed or by pressing and holding the M-button
for 3 seconds the year will ash on the display. You can change the year by
pressing the START button. To conrm the year press the M-button. The
month will ash.
