About the Preset Memory No.
This projector has 38 types of preset data for input signals (the preset memory). When the preset signal is input, the projector automatically detects the signal type and recalls the data for the signal from the preset memory to adjust it to an optimum picture. The memory
number and signal type of that signal are displayed in the Information 
menu.
You can also adjust the preset data through the Screen 
menu.
This projector also contains 20 different user memories beside the preset memories used for inputting analog computer signals. You can save input signals that have not been preset on these user memories.
When an unpreset signal is input for the first time, a memory number is displayed as 0.
When you adjust the data of the signal in the Screen 
menu, it will be registered to the projector. If more than 20 user memories are registered, the newest memory always overwrites the oldest one.
See the chart on page 66 to find if the signal is registered to the preset memory.
Note
When the aspect ratio of input signal does not match the screen size, a part of the screen is displayed in black.
