require adjustment. In the event the scale should need re-calibration, the following calibration
procedure should be performed. To maintain the scale's high degree of accuracy, it is
recommended that a qualified technician with certified test weights re-calibrate the scale.
In order to perform Setup and Calibration, it is necessary to remove the "Do Not Remove" sticker
from the lower right side of the scale. With the sticker removed, locate the Setup and Calibration
switch in the opening closest to the front of the scale. Refer to the figure on the next page.
NOTE: If operating from batteries, install the batteries making certain that they are
positioned in accordance with the drawing on the circuit board. If using the
optional AC power adapter, insert the plug into the jack on the back of the scale.
