Backing Up the File Containing the Factory Gamma Value

When you first start ImageDirector it automatically reads in the factory settings of the projector’s gamma value. A data file containing the factory pre-set gamma value that was read in is automatically generated and is stored in the “ImageDirector” folder with the name “VPL-VW12_serial number.ldt.” (For example, for a model VPL-VW12HT projector with the serial number 0017416, the file name would be [VPL-VW12_0017416.ldt].) This file is necessary to return the projector’s gamma value to the factory setting (Reset). Do not change the file name, delete the file, compress it, or modify it. If you do, you will not be able to return the projector’s gamma value to the factory setting.

If, by some chance, the computer where this file is stored is damaged, to avoid losing the data, we recommend preparing a floppy disk to backup the saved data file.

To do so, follow the procedure outlined below.

1 Select [Backup] from the [FILE] menu. The following dialog box appears.

2 If you are going to save the file on a floppy disk in the floppy disk drive (A:\), insert a disk into the drive and click the [Save] button.

A backup file is saved on the floppy disk.

If the following message appears

Insert a floppy disk into the drive and click the [Retry] button.

If you are saving the file somewhere other than on a floppy disk

Specify the location in step 2, and click the [Save] button.

Note

Even if you enter another file name in step 2, the file name will still be set to [VPL-VW12_serial number. ldt]. Do not change this file name.

If the copy of the file containing the factory setting of the projector’s gamma value is lost or deleted from the “ImageDirector” folder, copy the backup file made in the preceding process to the “ImageDirector” folder.
