The scale can be used on AC power immediately. Allow the battery to charge for 12
hours before using the scale on battery power. The Scale will automatically switch to
battery operation if there is a power failure or the power cord is removed. With AC
power, the scale is constantly charging, so the battery charge indicator will remain lit.
The scale can be operated during charging, and the battery is protected against
overcharging.
For maximum operating time, the battery should be charged at room temperature.
