1. When the appears on the upper right corner of the LCD,
the battery is exhausted and needs replacement.
2. Pull the battery cover off in the direction shown below.
3. Pull out the battery with a sharp objects such as pen. Keep
exhausted battery from
reaching by the children.
4. Place a new 1.5V D.C.
button size battery type
SR41 or LR41 or equiva-
lent in the chamber with
positive side faced up and
negative side faced down.
5. Install the battery cover
back.
1. To push the On/Off button by the display window. The display will
read for 2 seconds and beep sound will be heard.
2. Releasing the on/off button, last measured temperature will be
shown for about 2 seconds. Then shows the self-test temperature
37.0°C(98.6°F) , and then Lo°C (Lo°F) displays.
3. Wipe or dip the probe with alcohol for disinfection. Position the probe
in oral, rectal or axillary site.
4. Once the degree sign °C (°F) on the display has stopped ashing (usu-
ally within 10 to 40 seconds), a Beep signal will sound for approx. 10
times, the measured temperature is shown on LCD window. The tem-
perature reading will not change after the unit is removed from testing
position. If the temperature <37.8°C(100.0°F ). the buzzer will alarm
“Bi---Bi---Bi---Bi---”. If the temperature ≥ 37.8°C (100.0°F). the buzzer
whose frequency is higher will alarm “Bi-Bi-Bi----Bi-Bi-Bi--” about 10
times rather than”Bi---Bi---Bi---Bi---”
5. The unit will automatically turn off in 10 minutes for energy-saving.
However, to prolong the life of the battery, it is suggested to press the
On/Off button to turn the unit off once the measurement is done.
6. Please dispose of any used battery and the thermometer according
to the local regulations.
Note: After step 2, if the room temperature is greater than 32.0°C
(89.6°F ), it will be displayed the room temperature.
Note: Usage of the probe cover may result in a 0.1°C(0.2°F) differ-
ence from actual temperature.
Note: To clean the probe before and after using the thermometer
to ensure an accurate reading and avoid cross contamination ap-
proximately.
