pertinent legal requirements are met.

1. Verify that the menu settings meet the local weights and measures regulations.

4. Set Approved Mode to On in the Balance Setup menu.
5. As shown in Figure 6-1, press the push button inside the hole.
Note: When Approved Mode is set to On, external calibration can't be performed.
