3.9.7. “Blue” MENU Button and Top-Level Menu
If no menu is displayed, the blue MENU button loads the main top-level menu. If the top-level
menu is displayed, it closes the menu. If a submenu is displayed, it displays the parent menu.
There are two versions of the main top-level menu. See Figure 3.6. One version, the Special menu,
contains illustrated depictions of some commonly used features. The other version, the Standard
menu, shows text selections that help with measuring and scanning cables. The bottom menu
selections are the same for both menus. You can toggle between these two versions by going to
MENU → Settings → Display → Special/Standard Menu.
