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 S

Sales & Technical Support Hotline. See the rear cover for
in your area.
When power is first applied to the AVT, the LCD screen displays

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.
