EAR THERMOMETER
Model TH839S
1883239-3C
Thank you for purchasing the ear thermometer TH839S.
This thermometer is designed with an advanced infrared and ambient temperature compensation technology for instantaneous
self-diagnosis and accurate temperature measurements. Do not use this device for Live & Dead decision or Safety related
applications. Please consult with doctor if you have health concerns.
If the thermometer detects a body temperature 37.5°C (or 99.5°F), three short beep sound will follow one long beep
sound to warn the user for potential fever.
1. In “Power Off” mode, press and hold the “Measure” button.
2. While holding it down, press the “ON/MEM” button.
3. Continue to press and hold the “Measure” button for 3 seconds after the power is on. The icon “°C” will be switched to icon “°F” .
You can also use the same process to change the LCD display from °F to °C.
1. Gently squeeze the opposite ends of the thermometer to pull off the probe cap.
NOTES:
• Do not use force to remove the cap.
• Always use a new and undamaged probe cover.
• Make sure the ear canal is clean.
2. Place a new probe cover on the connection ring.
NOTE: Make sure to place the “Adhesive Side” of probe cover “Upward.”
4. Push the connection ring until the “Click” sound. This means the probe cover has been installed
successfully.
NOTE: If the probe cover did not install well, the “ ” icon will flash on the LCD screen and
can’t take the ear temperature (will hear 4 beep sounds without reading shown on the LCD
when measuring) on the LCD screen. Please check the setting of the probe cover again.
3. Align the probe with the center of probe cover.
Insert the probe into the probe cover on the connection ring.
ATTACHING A PROBE COVER
1. Press “ON/MEM” button to power on.
The thermometer is ready for use after the ear icon stop flashing and two short beep sound.
2. Gently pull the ear back to straighten the ear canal and snugly position the probe into the
ear canal, aiming towards the membrane of the eardrum to obtain an accurate reading.
3. Measuring the ear temperature: Use the index finger to trigger. Press the “Measure”
button until you hear a long beep.
4. Power off
：
Press and hold the “ON/MEM” button to turn off the unit. Device will automatically shut down after 1 minute pending
to extend battery life.
NOTES:
• Holding the thermometer too long may cause a higher ambient temperature reading of the probe. This could make the body
temperature measurement lower than usual.
• Before the measurement, please stay in a stable environment for 5mins and avoid exercising or bathing for 30mins.
• It is recommended that you measure 3 times with the same ear. If the 3 measurements are different, select the highest temperature.
• To avoid the risk of cross contamination, please clean the probe according to “Care and Maintenance” section after each use.
• Clinical repeatability: 0.18°C (< 1 year old), 0.17°C (1~5years old), 0.15°C (>5years old)

WARNING
• Do not forcibly insert the probe in the ear.
• If you feel discomfort such as a pain during the measurement, stop using the unit immediately. It may injure the external auditory
canal.
• Do not use this unit if suffering from ear disease such as otitis externa or otitis media. It may worsen the condition.
• Do not use this unit when the external auditory canal is wet such as after swimming or taking a bath. It may injure the external
auditory canal.
• Conducting self-diagnosis based on the measurement results and/or treatment can be dangerous. Please follow the instructions of
your doctor. Self-diagnosis may worsen the symptoms.
• Do not use this unit without attaching a probe cover.
• If the probe cover becomes dirty with earwax or other substances, replace it with a new one.
• Correct measurement result may not be obtained if dirty probe covers are used.
• Proper installation of the probe cover ensures accurate measurements.
• If device is accidentally used without a probe cover, clean the probe as follows:
(a)Please use the cotton swab with the Alcohol (70% concentration) to clean the lens (on the inside of the probe).
(b)Allow the probe to fully dry for at least 1 minute.
• Only use one probe cover at a time.
• If there is any temperature difference between the places where the unit is stored and where you are going to measure, leave the
unit in the room where you are going to use it for more than thirty minutes to allow it to reach room temperature first, then
measure.
• If the ear is cold, wait until the ear is warmed up before taking a temperature measurement. The measured result may indicate low
when you use an ice bag or an ice pack or immediately after coming in from the outside in winter.
• Do not touch the infrared sensor with a finger or breathe on it.
• The probe is the most delicate part of the thermometer. Use with care when cleaning the lens to avoid damage.
• Do not attempt measurements when the thermometer is wet as inaccurate readings may result.
• Store the unit out of children's reach.
• In an emergency case, if a child swallows a battery or a probe cover, immediately consult with a doctor.
• Do not use a probe cover after someone else has used it. This can lead to cross infections such as otitis externa.
• Do not throw batteries into a fire. The battery may explode.
• Children may try to measure by themselves and may damage the ear.
GENERAL SAFETY PRECAUTIONS
• Do not apply a strong shock to, drop, step on, or vibrate the main unit.
• Do not use this unit other than for measuring the temperature in the human ear.
• Do not use a portable phone near the unit.
• The main unit is not waterproof. Be careful when handling this unit so that no liquid (alcohol, water, or hot water ) will get into
the main unit.
• Do not disassemble, repair, or modify the unit.
• When you inform your doctor of your temperature, make sure you state that you measured the temperature in the ear.
