To delete a saved preset in the Clear submenu of the input, select the preset number, then press the NEXT button to clear the preset.

To recall an input's saved preset, select the input and press the input button successive times to activate each saved preset for that input.

Each recalled preset will display the message "Input X Memory Y" where "X" refers to the input (1 to 4) and "Y" refers to the preset

(1 to 3).

NOTE If no signal is present at the input, no preset can be saved

and the "No Signal" message will appear as part of the

default cycle.

5 Advanced configuration – The Detail feature controls output sharpness. The adjustment ranges from 0 to 63.

The Filter mode reduces or eliminates aliasing and the resultant

"jail bar" effect. For digital displays, set the filter On to reduce high frequency noise. For CRTs, set the filter Off.

Blue mode can be set On/Off. Setting this mode On will pass only sync and blue signals to the display for setup purposes. The Blue mode will be effective for RGB pass-through and YUV input signals YC input signals will pass the Y, but not the C signal, so the output display will be black-and-white only.

Autoswitch mode causes the highest numbered input that has a signal present to be automatically selected. This mode is enabled by setting Autoswitch to On. Setting this mode Off will disable Autoswitch.

Enhanced mode will enabled/disabled automatic gain control. A weak signal level will be increased, and an excessive signal level will be decreased. This mode can be set On or Off.

Exit – Return to the default menu cycle by pressing the NEXT button, or return to the Input configuration menu by pressing the MENU button.
