Precautions 

 

The thermometer includes a monitor battery. 

 

Refer to "Replacing the battery" before a measurement, open the battery cover and install the battery. 
When installing the battery, a current temperature is displayed. 
The accessory battery is for an operation monitor and may be short battery life. 

 

Replacing The Battery 

 

A coin battery (LR44) is used. When displaying faint characters, replace the battery as follows: 

1.  Turn over the AD-5625. Turn the battery cover in a 

counterclockwise and remove it. 

 
2.  Remove an old battery. 
 
3.  Install the battery so that its plus side (

+

, flat side) 

is upper face. 

 
4.  Reattach the battery cover and turn it in clockwise. 
 

Caution 

  Be sure to face the + side up when installing a battery. 
  Use the specified battery (LR44) only. 
  Do not disassemble, heat, short-circuit, dispose of in fire or attempt to recharge the battery. It may explode or 

leak and cause personal injury. 

  Keep the battery out of the reach of children. If swallowed, consult a physician immediately. 
  Follow the local regulations when disposing of a used battery. 
  To keep the thermometer watertight, do not damage the rubber ring or remove it from the battery compartment. 

 

Display Mode 

The thermometer has three display modes. 

Displaying mode 

Display example
