Configuring the Scaler
The LCD on the front panel of the scaler provides access to a menu that allows you
to configure the scaler.
• To access the menu, press the input button and the rate button simultaneously,
and hold them for two seconds. The Autoswitch menu appears in the LCD.
• To step through the menus, press the input button.
• To exit the menu, step through the menus until the Detail menu appears, and
then press the input button one more time. Or, wait eight seconds without
pressing any buttons or turning the adjust knob, and the menu reverts to the
default screens.
