OPERATION
The balance can be used on AC power immediately after the battery is installed. Allow the battery to
charge for 12 hours before using the balance on battery power.
While under rechargeable battery operation the Battery Icon will be lit. When the AC Adapter is
charging the battery icons will blink. Once the battery icon stops blinking the battery is fully charged.
When there is approximately 30 minutes of power remaining the battery icon will blink on/off every
0.5s. When the shutoff voltage is reached the display will alternately flash Batt and LowJ for 15
seconds then the balance will shut down. The balance will not power up if the shutdown level voltage
is detected.

Whenever possible use AC power as this will increase the life of the battery. Battery life is directly
related to the number of discharge cycles it experiences.
The number of hours that the balance can run on the battery depends on many factors. Backlight, IR
Sensors and Interface Options will reduce the hours before a recharge is needed. For optimum
battery life turn these features off. Under average conditions the battery should last around 100 hours
before needing a charge.
REMOVING THE RECHARGEABLE BATTERY OPTION
To convert the balance to operate on dry cell batteries follow these steps.
1. Disconnect the Power Adapter.
2. Disconnect and remove the battery.
3. Remove the Recharge Circuit board.
4. Install the Battery Connector. Refer to step 3 above where it was removed.
5. Install 4 C cell batteries or connect the Power Adapter.
