The PM175 has a menu-driven setup. To enter the menus, press and release the SELECT button.

The SELECT button selects (highlights) an active window in which you can select or change a desired menu item. The button operates once it’s briefly pressed and released.

The UP and DOWN arrow buttons scroll through menu items in the highlighted window forwards and backwards, and allow changing a highlighted item when entering numbers.

The ENTER button confirms the selection of a menu item or a number in the highlighted window, thus allowing to enter a submenu or to store a changed item.

The ESC button is “Escape” leaving the highlighted item unchanged or returning to the upper level menu.
