EN-6
Before using the scale for the first time, the internal rechargeable battery should be fully charged
for up to 15 hours. The scale can be operated during the charging process. The battery is
protected against over charging and the scale can remain connected to the AC power line.
Plug the AC Adapter into the receptacle marked "Power In" located on the underside of the scale and allow
it to charge. While the battery is charging, the segments in the battery symbol will alternately light. When
the battery is fully charged, the battery symbol will disappear.

Battery Power

The scale can be operated on the internal rechargeable battery when AC power is not available. The scale
will automatically switch to battery operation if there is a power failure or the power cord is removed. A
fully charged battery can operate the scale for up to 120 hours (with the backlight off) independent of the
AC power line.
During battery operation, the battery symbol will light to show the current discharge status of the battery (1
segment = 25% capacity). A flashing symbol indicates that the battery requires recharging. The scale will
automatically turn off when the battery is fully discharged.
BATTERY IS TO BE REPLACED ONLY BY AN AUTHORIZED OHAUS SERVICE DEALER.
RISK OF EXPLOSION CAN OCCUR IF REPLACED WITH THE WRONG TYPE OR CONNECTED
IMPROPERLY.
Dispose of the lead acid battery according to local laws and regulations.

2.5 Initial Calibration

When the scale is first installed, a SPAN calibration should be performed to ensure accurate weighing
results. Before performing the SPAN calibration, be sure to have the appropriate calibration weights. Refer
to Section 3.7.1.
