Figure 1.3 Oldest style main PC board

The jumper shown in Figure

1.3

is inside the small red rectangle.

It is shown in the ‘calibration locked’ position. The scale cannot
be calibrated with the jumper on the two bottom pins. Pull the
jumper up and move it to the top two pins to unlock calibration

5.

Reverse the disassembly procedure to reassemble the scale.
