SECTION 4
FRONT PANEL AND ALIGNMENT OVERVIEW
This section describes the CP500 LCD display and operation of the front panel
controls, along with of an overview of the general principles involved in the
alignment of Dolby cinema equipment. It is useful to develop an understanding of
why the CP500 is aligned as described in this manual. If the installer is already
familiar with the CP500 and these principles, or is in a hurry to complete the
installation, this section may be read later. Continue the installation procedure
beginning with Section 5.

(SK7)
(SK8)
The buttons located on each side of the LCD display are sometimes called "soft
keys"(SK). That is, they do not have a single fixed function but rather their function
is software controlled and changes based on the current screen displayed. The
purpose of each button is shown on the display and can change with each different
displayed screen.
4.1.3 Hard Keys
FORMATS
The single large and four small keys along the bottom of the display are the "hard
keys". Their function is labeled on the panel. The large key on the left,
FORMATS, is used to return to the Format Selection (Current Formats) screen
from any other menu screen. This screen is displayed during normal day-to-day
operation of the CP500. If any other screen or menu is displayed, this button returns
the display immediately to this "top" of the menu tree.
MENU
The MENU key is used as the first step in selecting all software functions and
menus except format selection. It selects or returns the unit to the top menu.
