Operations

The following paragraphs detail the power-up process and then describe the menu
system, the picture, and the selection of the front panel security lockout.

Power

Power is applied when the power cord is connected to an AC source. When AC
power is applied, the switcher performs a self-test that cycles all of the front panel
LEDs on and off from left to right. An error-free power up self-test sequence leaves
the selected input LED and the selected Output Rate LED on. If the picture-in-
picture feature was turned on when the switcher was powered down, the PIP On
LED and a secondary input LED are also lit.
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.
The Color/Tint control affects only certain interalaced component video,
composite video, and S-video, as shown in the following table.
