The Automatic Power-Off Function And Turing Off Thermometer 

The Automatic Power-Off Function 

  The thermometer has an automatic power-off function. When pressing the    AUTO-OFF    button during the 

measurement display, the indicator "AUTO" is displayed and the automatic power-off function is performed. When 
no operation is performed for six or seven minutes, the thermometer is turned off automatically. 

 

Turing Off Thermometer 

  When turning off the thermometer immediately from the mode 

displaying the indicator "AUTO", press the    AUTO-OFF    button 
twice. 

 

The Way Of Use Concerning The Ring 

 

The thermometer can hold with the ring of the sheath folder. 
when supporting the thermometer with the ring, insert the 
sensor sheath into the ring. 

 

Cleaning And Keeping 

 

Clean the sensor sheath for accurate temperature measurement and keep it. 

 

Cleaning The Thermometer With Water 

 

The thermometer is water-resistant type. When cleaning heavy dirt, clean the thermometer with a cloth 
moistened with water and a mild detergent softly.
