Extron electronic AVT 200HD manual Powering On, Power-up and Default Cycle Screens Example

Powering On

Apply power by connecting the provided IEC power cord to the rear panel IEC connector and to an AC source. The tuner performs a self-test that flashes the three TV format indicators in order from top to bottom and then turns them off while the initial two power-up screens are displayed in the LCD screen. At the completion of the self-test, the LED display shows the current channel, the appropriate TV format LED is lit, and the LCD window displays the default screen cycle.

If an error occurs during the self-test, the AVT locks up and does not operate. If this occurs, call the Extron S3 Sales & Technical Support Hotline. See the rear cover for contact information in your area.

When power is first applied to the AVT, the LCD screen displays Extron Electronics, then AVT 200HD with the current firmware version. If the AVT self-test completes successfully, the default cycle begins, in which the display alternates between a screen showing the current output resolution and refresh rates and a screen showing the channel to which the AVT is currently tuned. These two screens continue to cycle on the screen when the menu system is not in use.

NOTE: Audio and video mute settings are not retained when power is cycled to the

AVT.

The flow diagram on the next page shows the order in which the screens appear at power-up.

Figure 13. Power-up and Default Cycle Screens (Example)

NOTE: If your AVT 200HD is new and no channel scan

has been performed, the two screens shown at right alternate on the LCD screen instead of the default cycle (see “Scanning for channels,” later in this section).

This cycle also appears after a system reset (see “Unit Reset Menu (Resetting from the Front Panel),” later in this section.) After the

first scan the default cycle is displayed after power-up.
