Radiant TH879S User Manual

TH879S Ear-Type Thermometer
Intended use: The infrared ear thermometer
measures the infrared heat generated by the
eardrum and surrounding tissue to reflect
patient's body temperature.
Intended operator: At least 11 years old (5
years intensive reading experience), no
maximum.
Thank you for purchasing the thermometer.
This thermometer is designed with an
advanced infrared and ambient temperature
compensation technology for instantaneous
self-diagnosis and accurate temperature
measurements. It is for home use, not meant
to replace a visit to the doctor. Please also
remember to compare the measurement
result to your regular body temperature.
Please consult with doctor if you have health concerns.
Operating Instructions:
NOTE：If there is any temperature difference between the places where the device is stored and where you are going to measure,
subject and the device should stay in the same room for at least 15 minutes before measurement.
1. Gently squeeze the opposite ends of the thermometer to pull off the probe cap. Do not use force to remove the cap.
2. Always use a new and undamaged probe cover. Make sure the ear canal is clean.
Warning: Choking from swallowing small parts and batteries by children or pets is possible, please keep small
parts and batteries at places where children and pets can't reach.
3. Install Probe Cover
1) Place a new probe cover on the connection ring. (See Figure 1)
NOTE：Make sure to place the "Adhesive Side" of probe cover "Upward."
2) Align the probe with the center of probe cover. Insert the probe into the probe cover on the connection ring. (See Figure 2)
3) 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,
4 beep sounds without reading shown on the LCD when measuring). Please check the setting of the probe cover
again.
Figure 1
Proper installation of the probe cover and using the specific probe cover ensure accurate measurements.
4. Press "ON/MEM" button to power on. The thermometer is ready for use after the ear icon stop flashing and two short beep
sound.
5. 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. (Fig.4-1)
6. Measuring the ear temperature：Use the index finger to trigger. Press the "Scan" button
until you hear a long beep. (Fig.4-2). After each ear measurement, wait
be ready for next measurement.
7. Power off：This device will automatically shut down after 1 minute pending to extend battery life.
NOTE：
a. Before the measurement, the subject should stay in a stable environment for 5mins and avoid the exercise, bath for
30mins.
will flash on the LCD screen and can't take the ear temperature (will hear

icon stop flashing to
Figure 4-1
b. It is recommended that you measure 3 times with the same ear. If the 3 measurements are different, select the
highest temperature.
c. To avoid the risk of cross contamination, please clean the probe according to "Cleaning and Storage" section after
each use.
d. The "Clinical Bias" is -0.2 ~ -0.4°C.
e. The "Limits of Agreement" is 0.58.
f. The "Repeatability" is 0.17°C.
Fever Indication:
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.
Switching between Fahrenheit (°F) and Celsius (°C):
In "Power Off" mode, press and hold the "SCAN" button, then press the "ON/MEM" button for 3 seconds, icon "°C" will be switched
to icon "°F". You can also use the same process to change the LCD display from °F to °C.
Memory Function:
When in power on, press the "ON/MEM" button to see the temperature stored. The thermometer provides 9 sets memory for the
body temperature.
Cleaning and Storage:
The probe is the most delicate part of the thermometer.
Use with care when cleaning the lens to avoid damage.
Storage temperature Range: It should be stored at room temperature between -20~+50°C, RH≦85%
Keep the unit dry and away from any liquids and direct sunlight. The Probe should not submerge into any liquids.
** If device is accidentally used without a probe cover, clean the probe as follows:
a. Please use alcohol swabs or cotton swabs moistened with 70%~75% alcohol to clean the probe lens.
b. Allow the probe to fully dry for at least 1 minute.
NOTE：Please check the device if damaged once it falls. If you can't make sure of it, please send the
complete device to the nearest retailer for recalibration.
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.
Changing the Battery:
This device is supplied with one lithium cell (CR2032 x 1).
1. Open the battery cover: Use the thumbs to push battery cover out.
2. Hold the device and flip the battery out with a small screwdriver.
3. Insert the new battery under the metal hook ○
4. Replace the battery cover.
