Operation, cont’d
IN1404XT Video Scaler and Switcher • Operation 3-4
8 Enter 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.
