Electronic Digital Thermometer Operation Instructions MT-B231
FEATURES
1. Internal function test will be carried out every time when the unit is turned on. It is so-called automatic self-test function. If it displays
, it means the thermometer is not
working properly. Please contact the supplier.
2. Temperatures can be taken from under an arm (external use) or under the tongue (oral use). It is suggested that rectal temperatures are taken on infants only when
external use is inconvenient.
3. This is a very sensitive device and results can be obtained within 60 ~ 90 seconds approximately.
4. If the thermometer is inadvertently left on after reading your temperature, it will automatically shut off after 10 minutes.
5. This is a small and light-weight unit (10 grams) and can be used by the whole family.
6. The ABS resin body presents no hazards compared to a broken mercury glass thermometer.

1.
After switching on the thermometer the display will show the last memorized data for approx. 2 seconds.
2.
The indicator will then display “Lo” for about 0.6 seconds.
3.
While the temperature is being measured, the current temperature will be permanently indicated and the “°F” mark will flicker during the measuring time.
4.
When the fluctuation of the temperature is below 0.04°F for 8 seconds, the “°F” mark will stop flickering and an electronic buzzer will sound. At the same time the final
temperature will be shown on the LCD. From now on the indicated temperature will fluctuate minimally.
5.
After measuring your temperature the temperature will be displayed on the LCD screen until you switch off the thermometer.
6.
To prolong the life of the battery, please switch off the thermometer after use by pressing button
. If the power is left on, the thermometer will automatically shut down
after 10 minutes to save power.
