1.6.2 Power ON/OFF

To turn the scale on, press and hold the On/Zero Off button for 2.5 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 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. When charging, the symbol will blink slowly and when fully charged the
symbol will stop blinking.
Notes:
When battery symbol blinks fast, approximately 30 minutes working time is left.
When [lo.bat] is displayed, the scale will shut off.
Charging the scale must be performed in a dry environment.
CAUTION: Battery is to be replaced only by an authorized Ohaus
service dealer. Risk of explosion can occur if the rechargeable
battery is replaced with the wrong type or if it is not properly
connected. Dispose of the lead acid battery according to local laws
and regulations.
