    If your TIA Thermometer displays 'LO', it indicates that the temperature reading is below the normal measurement range. In BODY mode, this means the temperature is below 90°F (32°C), and in SURFACE mode, it means below 32°F (0°C). Other possible causes include hair or perspiration obstructing the reading (brush or wipe away before measuring), air flow affecting the reading (use away from drafts), measurements taken too rapidly (wait at least 15 seconds between measurements, though a 1 minute interval is recommended), or measuring distance too far (keep device 2 – 6 inches or 5 – 15cm from body/surface).

    If your TIA Thermometer displays 'HI', it means that the temperature reading is above the normal measurement range. This is above 109°F (42.9°C) in BODY mode and above 140°F (60°C) in SURFACE mode.

    If your TIA Thermometer displays a body temperature less than 89.6°F (32°C), it might be in SURFACE mode. To switch to BODY mode: 1. Press the trigger to activate the unit. 2. Press and hold the “°C” button for about 3 seconds until F1 is displayed. 3. Press the “°F” button once to show F3. 4. Press the “M” button to display the current setting. 5. Press the “°F” button to change from SURFACE to BODY (or vice versa). 6. Press the “M” button to select the mode. 7. Press the trigger to exit.
