[Diagnostic Devices](https://support.omply.com/en/diagnostic-devices?hsLang=en) November 5, 2026 # Thermometer: guide and troubleshooting The infrared ear thermometer measures your body temperature from your ear in about a second. The device is the Joytech DET-1015b. It connects to your phone over Bluetooth and runs on two AA batteries, which aren't included. The package has 15 disposable covers. ### How to use the thermometer Take the measurement during your appointment with your doctor or right before it. That way your doctor is sure to get your own readings, not an earlier measurement taken by someone else, such as a family member. Be indoors for at least ten minutes before you measure. If you've just eaten, had a drink, exercised or showered, wait a moment. 1. Fit a new, clean funnel-shaped cover on the tip of the thermometer. Replace the cover between measurements. 2. Press the ON button. The device beeps once, then gives a double beep when it's ready. 3. Insert the thermometer firmly into your ear, as deep as is comfortable, and press the measurement button. 4. The measurement takes about a second, and a beep tells you it's complete. 5. The result is saved locally on your phone in the Omply app, and you can share it with your doctor from there. If you're in an appointment, your doctor sees it right away. You can then turn off the device. Always measure from the same ear. If you measure again, wait about 20 seconds between measurements. ### If something goes wrong - **The display shows Er 1.** You measured before the device was ready. Wait for the ready sign and measure again. - **The display shows Er 2 or Er 4.** The room is too cold or too hot, or its temperature changed quickly. Leave the thermometer for at least 30 minutes in a room at 10–40 °C (50–104 °F). - **The display shows Er 3.** The thermometer was in the wrong position or it moved. Place it in your ear again and measure. - **The display shows Er 5.** Take out the batteries, wait a minute and put them back. If the message returns, contact customer support. - **The display shows Er 6 or a house icon.** The device is in object mode. Switch to ear mode by holding down the settings button. - **The display shows Hi or Lo.** The reading is outside the measurement range. Check that the cover is intact and clean, and measure again. - **The display shows a battery symbol.** Replace the batteries with two new AA alkaline batteries. - **The result looks odd.** Lying on your ear, covering your ears, a very hot or cold environment, swimming or bathing can change the reading. Wait 20 minutes. Also take out hearing aids or earplugs 20 minutes before measuring. - **The Bluetooth symbol is flashing on the thermometer.** The device isn't connected to the app. The symbol stays on when the connection is made.
