Operation, cont’d

8Enter button — The Enter button either activates a submenu or function in the IN1404XT menu system or saves a changed value. See Front Panel Operations in this chapter for details.

The effects of all adjustments are visible on the screen or audible on the audio output, but they are temporary unless saved. The adjustments return to their previous settings when the adjustment screen exits by either a timeout or the operator pressing the Menu button. For a setting that you have made to become permanent (until replaced in favor of a newer setting), it must be saved by pressing the Enter button. With the exception of the volume adjustment (see item 4 , above), if you do not save the value by pressing the Enter button, your adjustment is lost.

Front Panel Operations

The following paragraphs detail the power-up process and then describe the menu system, the picture adjustments, and selection of executive mode.

Power

Power is applied when the power cord is connected to an AC source and the rear panel Power ( /) switch is set to the on ( ) position. When AC power is applied, the scaler performs a self-test that blinks all of the front panel LEDs twice and then defaults to indicating the selected input. An error-free power up self-test sequence leaves all of the LEDs, with the exception of the selected input’s LED, off. If Blank or Mute Audio were selected when the scaler was powered down, those LEDs light too on power up.

The selected input, the picture adjustments, and other current settings are saved in non-volatile memory. When power is applied, the latest configuration is retrieved.

Menu operation

Figure 3-5 shows a flowchart of the main menus in the menu system. Each menu leads to a series of submenus that accomplish individual tasks or groups of tasks.

Menu button — Press the Menu button to activate the menu system or to back up one level from the currently selected menu or submenu (for example, pressing the Menu button in the Video submenu returns the scaler to the Main menu).

, , , and buttons — Press the , , , and buttons to move the highlight bar over submenus or selections.

Enter button — Press the Enter button to select a highlighted submenu or selection. Press the Enter button to save a value that you have set to memory. On the menu system flowcharts (figure 3-7, figure 3-8, figure 3-9, figure 3-11, figure 3- 12, and figure 3-13) and in the following descriptions, “save” functions of the Enter button are shown in a bold, italics font: Enter (and save).

For a setting that you have made to become permanent (until replaced in favor of a newer setting), it must be saved by pressing the Enter (and save) button. With the exception of the volume adjustment (see item 4 ), if you do not save the value by pressing the Enter (and save) button, your adjustment is lost.

To exit an adjustment screen without saving the change, press the Menu button to return to the previously selected screen.

To return to normal operation (no menus), let the scaler remain idle for 15 seconds until the selected screen times out, or press the Menu button repeatedly until the Main Menu is deselected.
