Why IR ear thermometer?
The tympanic membrane (eardrum), and the hypothalamus, the part of the brain which controls body temperature, share a common blood supply, so tympanic readings rise and fall rapidly with core temperature (deep-body temperature). This makes the ear temperatures one of the best indicators of internal body (core) temperature.

What are normal temperature values?
Human body temperature varies from person to person. One person’s body temperatures are different from time to time. Therefore, it is very important to know your normal body temperature range. Because of this, we recommend that you measure yourself when healthy to establish reference temperatures which will make you feel more confident of the measured temperature when ill.

Information You Should Know Before Operating the IR Ear Thermometer
How to use the IR ear thermometer correctly?
1. It is useful to try this thermometer on yourself first to become familiar with its operations.
2. Please do not take the temperature immediately after waking up. Sleeping on the ear may cause the temperature to be higher than normal.
3. It is common for the readings to be slightly different between the right and the left ear. Therefore, we suggest using the same ear to obtain temperature.
4. To make the ear canal straight for measurement:

For Children under 12 months: Make the ear canal straight by pulling the ear back.

Ear Back

For Children over l 2 months and Adults: Make the ear canal straight by pulling the ear back and up.

Ear back and Up

5. This IR ear thermometer automatically converts measured ear temperature reading to oral temperature.

Preparation for Use
Installing/Replacing the Battery

  1. Use a pointed object such as the tip of a pen to push down on the battery cover lock.
  2. Pull the cover off while the cover lock is pushed down.
  3. Extract the battery from the battery holder with an insulated instrument. Avoid using any sharp metal object in this operation. Discard old battery properly.
  4. Place one new 3 VDC lithium battery CR2032 or equivalent into the chamber with the positive (+) side up and the negative (-) side down.
  5. Replace and fasten the battery cover. securely.

Warning :
Battery Contains Mercury. Do Not Put in Trash. Recycle or Manage as Hazardous Waste. Never dispose of battery in fire. Dispose in recycling trash only. Do not recharge, put in backwards or disassemble. This may cause explosion, leakage and injury.


How to Operate the Thermometer

  1. Press and release the START/STOP button to turn on the unit. (Figurel) A beep is heard. After about 2 seconds, the display shows that the unit is ready for measurement. (Figure2)
  2. Place the probe into the ear canal then press and release the START/STOP button again to start measurement.
  3. While it is measuring, the display will show an “arrow” sign. (Figure3)
  4. A “beep-beep”sound is heard when the measurement is completed. (Flgure4)
  5. After the smiling face symbol stops flashing, you can repeat measurement by pressing the START/STOP button again.
  6. Turn off the unit by pressing and holding the START/STOP button for 3 seconds until the OFF message is displayed. A long beep is heard. (Figure5)
How to Operate the Thermometer

For Centigrade and Fahrenheit Switchable Models: The Centigrade or Fahrenheit mode can be switched by turning the unit on then pressing the START/STOP button again immediately and holding it down. The display will show “CH” with “F” or”C”. Release the button when the mode you desire is in the display window. The unit will show “L” with the degree sign and the smiling face symbol in the display and is ready to take a new temperature reading.

Switchable Models

Operational Hints:

  1. Between each measurement, please allow a 5-second interval in order to obtain the most accurate result.
  2. Ensure that the probe lens is clean before each measurement. Dirty probe lens may cause Inaccurate measurement.
  3. Because the thermometer is a very sensitive device, it must be at room temperature approx. 60.8-104°F (16-40°C) for at least 30 minutes before using to avoid any incorrect measurements.

Performance of the device may be degraded if the device is operated or stored outside the stated temperature and humidity range or if the patient’s temperature is below ambient (room) temperature.

Memory Mode
Recalling Memory:

  1. If the power is on, turn off the power first.
  2. Press and hold the START/STOP button for about 3 seconds until the last recorded temperature is displayed.

3. For models with 9 memories Press the START/STOP button repeatedly will take you to each recorded temperature in the memory. you may toggle the button to see the recorded temperatures.

recorded temperatures

4. After you release the START/STOP button the unit will return to the measurement mode.


5. “L” will appear on the display. The unit is then ready for Measurement again.

Measurement again

6. It is now ready to take a new temperature reading.
