3.15 Securing the Menu and Key Lock menu settings
A slide switch located on the Main PC Board inside the housing is used to secure the Menu Lock and Key Lock menu settings.
When the switch is set to the ON position, the Menu Lock and Key Lock menu settings may be viewed but not changed.
Open the housing as explained in Section 2.3.1. Set the position of the switch to ON as shown in Section 1.2, Figure 1-3, Item

When the switch is in the ON position, the start up display includes the LOCK ON message.
Note: This switch is also used in conjunction with the Legal for Trade menu item. When the Legal for Trade menu is set to ON,
the switch must be set to the ON position to prevent calibration and changes to metrologically significant settings. Refer to
Section 6 for more information.
