5.5 Turn on or off the buzzer/speaker/vibration
The PC809, PC809EV, PC809V models are different in how they
interact with users when measurement is complete: the PC809 uses
a buzzer to ‘beep’, the PC809EV communicates the temperature in
English through a speaker and the PC809V uses a motor to vibrate.
Please check the label on the back to determine which thermome-
ter model you are using.
If you want to turn on/off the buzzer/speaker/vibration, when the
thermometer is shut down, press the Set button for about 9
seconds until you see the ‘ON’ symbol or ‘OFF’ symbol appear
on the screen, then release the button. Press the Set button again
and the ‘ON’ symbol or ‘OFF’ symbol will be converted to the
other.
After selection, press the button for about 5 seconds to automati-
cally save the setting and shut down the thermometer.
5.6 Set threshold for low fever
This thermometer has 37.5℃/99.5℉ preset as an alarm temperature
for low fever. However, 37.5℃/99.5℉ is only a reference value. At
this temperature, different people feel different, with some feeling
uncomfortable and others feeling fine. If you do not agree with this
low fever threshold, after consulting your doctor, you can manually
change it to suit your own situation.
When the thermometer is shut down, press the Set button for about
12 seconds until you see the orange status light on the screen,
then release the button. Ignore the other symbols that appear in
the process.
By pressing the Set button, you can increase the threshold by 0.1
℃/0.2℉ each time. The adjustment range is from 37.5℃/99.5℉ to
37.9℃/100.2℉. Once it reaches the Max. value, press the button
again; it will return to the Min. value and the cycle will repeat.
After adjustment is complete, press the button for about 5 seconds
to automatically save the setting and shut down the thermometer.
