2.5.1 Battery Power:
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 10 in table 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.
TABLE 2-1

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.
