Frequently Asked Questions - DualScan Ultra Mobi
How do I switch between forehead and ear mode?
Press the mode button located on the front of the thermometer. The display will indicate 'Forehead' or 'Ear' icon. Choose the desired mode before taking a measurement.
How do I change the temperature unit from Celsius to Fahrenheit?
With the device off, press and hold the power button for about 5 seconds until the unit flashes. Then press the power button again to toggle between °C and °F. The new setting will be saved automatically.
What is the correct way to measure forehead temperature?
Place the probe flush against the center of the forehead, about 1 cm from the skin. Press the scan button and keep it pressed for 1-2 seconds. The reading will appear on the display with a beep.
How do I clean the thermometer probe?
After each use, wipe the probe gently with a soft, dry cloth. For disinfection, use a cloth slightly dampened with 70% isopropyl alcohol. Do not immerse the thermometer in liquid.
What should I do if the thermometer shows an error message?
Common error codes: Err1 (ambient temperature too high/low), Err2 (contact error), Err3 (measurement out of range). Turn off the device, wait 5 minutes, and try again in a stable environment. If the error persists, replace the batteries.
How many readings can the thermometer store?
The thermometer can store up to 25 previous readings. To recall them, turn off the device, then press and hold the memory button (M) for 2 seconds. Use the mode button to scroll through the stored values.
Why does the backlight turn red?
The backlight turns red and an alarm sounds if the measured temperature is 38°C (100.4°F) or higher, indicating a possible fever. A green or blue backlight indicates normal temperature.
Can I use this thermometer on a newborn?
Yes, the thermometer is safe for infants. For newborns under 3 months, we recommend using forehead mode. Always consult a pediatrician if you are concerned about your baby's temperature.
How long do the batteries last?
With typical use (about 20 measurements per day), the two AAA batteries should last approximately 1-2 months. The low battery indicator will show when replacement is needed.
What should I do if the thermometer gets wet?
Immediately dry the thermometer with a soft cloth and remove the batteries. Let it air dry thoroughly in a warm, dry place for at least 24 hours before using it again. Do not use a hair dryer or microwave.
