Unpacking Your Scale

Carefully unpack and inspect the shipping container for evidence of shipping
damage. If such evidence is discovered, stop unpacking and immediately
notify the carrier to arrange to have the shipment inspected by an authorized
representative.

1. Open the box and carefully remove the scale from the shipping carton.

Before using your scale for the
first time, use the AC adapter
to plug the scale into a power
outlet for 8+ hours. This will
allow the scale to fully charge
the battery prior to use.

2. Remove the AC adapter from the packaging material.

3. Before using your scale for the first time, use the AC adapter to plug the
scale into a power outlet for 8+ hours. This will allow the scale to fully
charge the battery prior to use.

4. Remove protective plastic covering from weight platter.

Weights And Measures Sealing

If your local Weights and Measures requires your scale to be sealed and will
not allow the weight hold feature to be active, see the section Weight Hold –
Weights And Measures Sealing for details on how to configure the scale to
deactivate the weight hold feature. Calibration may be required prior to
Weights and Measures inspection. Please contact the service department at
1-800-458-7062 for the nearest dealer in your area.

Battery Operation

Charging The Battery

Battery Replacement

Each unit includes a sealed lead acid battery. A fully charged battery will
provide power to the unit for 12 to 40 hours (depending upon display back­light usage). When the scale detects the battery has approximately 1 hour of
use remaining before full shutdown, the display will flash “LobAt” every 15
seconds.

To charge the battery, plug the AC adapter into the rear of the scale. The
AC PWR annunciator will indicate the unit is plugged into a live AC outlet
and charging the battery. After 5 minutes of no activity, the scale will go into
sleep mode, and display CHArG. To remove this message and use the
scale, press the ZERO key.

Remove the cover on the underside of the scale by loosening the 2 screws.
See Figure 1. Unplug the battery cables and replace with a new battery,
black cable to (-) terminal, red cable to (+) terminal. Refit the cover and
tighten the screws.
