  1. To achieve accurate readings, make sure a clean Probe Cover is in place before each measurement and the ear canal is clean.
    a. Install the Probe Cover by clockwise rotating; then fix it.
    b. Remove the Probe Cover by anti-clockwise rotating; then release it.
  2. Press the “On/Off/Memory” button, the thermometer is ready for use after the ear icon is flashing, two beeps are sounded, and three dash segments are appeared.
  3. As the ear canal is slightly curved, you have to pull the ear slight up and backwards before inserting the probe. This is important so that the tip of the Probe Cover can be pointed directly at the eardrum.
    a. Before measurement, the correct installation of the Probe Cover ensures an accurate measurement.
    b. Replace with a new Probe Cover after approx. 30 times of use to ensure an accurate reading.
    c. This thermometer must only be used with Rossmax Probe Covers, other covers can lead to inaccuracy. If running out of Probe Covers, please contact the original seller or distributor for buying new Probe Covers. Do never measure without Probe Cover or with a broken Probe Cover.
  4. Measuring the ear temperature:
    • With 1” Measurement: Use the index finger to trigger, by pressing “Start” button, a long beep will be sounded when measurement is done.
    • With 3” Scanning Mode: For highest accuracy always use 3” Scanning Mode. Use the index finger to trigger, press and hold the “Start” button for 3 seconds to take measurement. Gently rotate the probe in the entire ear canal in order to find the highest temperature. Release the “Start” button until hearing a long beep sound and the measurement is completed.
  5. For the next measurement, ensure that there is no breakage or stains of Probe Cover before each measurement, otherwise replace the Probe Cover with a new one.
  6. Power off: If left idle for more than 1 minute, device will automatically shut off for extending battery life. Or press “On/Off/Memory” button for at least 3 seconds to turn the device off.
  7. Fever alarm: When the measuring temperature is higher than 37.5 °C(99.5°F), the reading will flash, the backlight will be enabled, and 4 short beeps will be sounded. If measuring temperature is higher than 42.2 °C(108°F), the display will show “Hi”, the backlight will be enabled, and 4 short beeps will be sounded.
    a. It is recommended that you measure 3 times with the same ear within a short period of time. If the 3 consecutive measurements are different, select the highest temperature; or do a 3” Scanning Mode measurement to find highest temperature.
    b. To avoid the cross contamination risk, please clean the probe and Probe Cover according to “ Clean and Storage” section
    after each use.

Enabling or disabling the beep sound
