The battery needs to be re-charged. While the battery is getting

OOOO

The scale is at zero. A weight has been tared, the display is showing the net weight.

re-charged, this symbol will be flashing.

The weight is stable.

The keys perform the following functions:

This key is used during setting of the user functions.

[High/Low/

Mode]

[Unit/]

It is also used during setting of the High and Low Limits for check-weighing facility and for setting the alarm function.

This key is used to change the weighing units while the scale is in the weighing mode. It is also used for advancing the digit while the scale is in the setting mode.

This key is used to deduct the weight of the container from the gross weight and thus to display the net weight only.

[Tare/]

[Zero/ ]

It is also used to increment the digit while the scale is in the setting mode.

This key is used to reset the zero position for accurate weighing while the scale is in the weighing mode. It is also used to decrease the digit during the setting mode.
