2. Remove the control box from the storage dock in right side of the weighing
platform by pulling the control box firmly from the dock.

DRS220, ensure the coiled cord does not touch the top of the weighing platform,
or inaccuracies may result.

The easel may be used straight for hanging, or folded at an angle for resting on
a level surface.

Resolution
The resolution (minimum incremental weight) than can be displayed by the DRS220
can be adjusted to make the display easier to read. Unstable loads or high winds
can cause the display to fluctuate erratically. By reducing the display resolution,
external influences can be minimized. As shipped, the DRS220 is set to MEDIUM
resolution, suitable for most purposes. The resolution can be changed to LOW,
MEDIUM or HIGH by repeated pressing on the keypad. The table 1 illustrates
the displayed resolution for each units mode vs. resolution. Regardless of the
resolution setting, the scale operates internally with the highest resolution; therefore,
only the displayed value is affected.
