TEST/ZERO
This switch will "test" the display by activating all of its segments. It then zeros the
scale. See the explanation for the ON button.
LAMP
This switch will back light the display for night use. The lamps only stay on while the
button is being pushed.
HOLD/RELEASE
When in the hold mode, the scale will constantly display the highest weight applied to
it. When in the release mode, the scale shows the actual weight upon it. The
indicating bar on the lower left side of the display is on when in the hold mode, and off
when in the release mode.
The indicating bar next to Bat comes on when the batteries are getting low. The
scale will continue to operate correctly for approximately two hours before shutting
itself off.
