a)  Press the On/Off button 2 times, one right after another. 

 

b)  Hold the second press down for more than 1.5 seconds. 

 

c)  Symbol  °F  or  °C  appears, with beep, on the display window. 

 
 

2. How to Operate

Otherwise,  Err  or  ---  alerts its malfunction. 
 

c)  Then, the ambient temperature or  Lo

°F

  ( Lo

°C

 ) displays on window with °F or °C 

blinking.  The thermometer is now ready for a temperature taking.  If there is no 
temperature taking in the coming 3 minutes, the thermometer will be 
automatically shut-off. 
 

d)  Put the probe head under the tongue, under the arm or in the rectum; according 

to the methods provided (see 5. Methods of Use).
