1.5.2 Power ON/OFF
To turn the scale on, press and hold the
On/Zero Off
button for 1 second. The scale
performs a display test, momentarily displays the software version, and then enters the
active weighing mode.
To turn the scale off, press and hold the
On/Zero Off
button until OFF is displayed.
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 (see item 11 in
figure 3-2) 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.
During battery operation, the battery symbol indicates the battery charge level
remaining. The indicator will automatically turn off when the batteries are fully charged.

service dealer. Risk of explosion can occur if the rechargeable
battery is replaced with the wrong type or if it is not properly
