The Model 690 and 692 thermometers use three standard alkaline AA batteries, which provide 
longer life than standard AA batteries. No battery charging is available. The thermometer 
display will indicate when the batteries need replacement.

The wall holder is easily secured to a wall. A locking mechanism with a removable key for 
securing the instrument is standard on the Model 692 Thermometer and is available as an 
option for the Model 690. Through the use of available long cord probes, the thermometer may 
be used without removing it from the wall holder.
