Note: If the lens, CCD and board in item 12-15, it is neces-

sary to adjust again. Item 12-15 adjustments other than these should be carried out in sequence. For 14 and 15, carry out adjustment after sufficient charging has taken place. In case of carrying out adjustment item 12 and 13 after adjusting item 14 and 15, adjust item 12 and 13 after turing off the power.

3-4. Setup

1. System requirements

Windows 98 or Me or 2000 IBM R -compatible PC with pentium processor CD-ROM drive

3.5-inch high-density diskette drive USB port 40 MB RAM Hard disk drive with at least 15 MB available VGA or SVGA monitor with at least 256-color display

2. Installing calibration software

1. Insert the calibration software installation diskette into your diskette drive.

2. Open the explorer.

3. Copy the DscCalDI_128c folder on the floppy disk in the FD drive to a folder on the hard disk.

3. Installing USB drive

Install the USB drive with camera or connection kit for PC.

4. Color Viewer

1. Turn on the switch and wait for 30 minutes for aging to take place before using Color Pure.

2. The luminance adjustment control on the color viewer should be set to around the middle position (memory 5) during use.

3. The fluorescent lamps which are used in the color viewer are consumable parts. After the cumulative usage time reaches 2000 hours, the color temperature will start to increase as the usage time increases, and correct adjustment will not be possible. When the cumulative usage time reaches 2000 hours, all of the fluorescent lamps should be simultaneously replaced with new lamps.

4. USB STORAGE INFORMATION

REGISTRATION

USB storage data is important for when the camera is connected to a computer via a USB connection. If there are any errors in the USB storage data, or if it has not been saved, the USB specification conditions will not be satisfied, so always check and save the USB storage data.

Preparation:

POWER switch: ON

Adjustment method:

1. Connect the camera to a computer. (Refer to 3-5. Connecting the camera to the computer on the page 16.)

2. Double-click on the DscCalDi128c.

3. Click on the Get button in the USB storage window and check the USB storage data. VID: SANYO PID: VPC-MZ2EX or VPC-MZ2 Serial: Rev. : 1.00

4. Check the “Serial” in the above USB storage data. If the displayed value is different from the serial number printed on the base of the camera, enter the number on the base of the camera. Then click the Set button.

5. Next, check VID, PID and Rev. entries in the USB storage data. If any of them are different from the values in 3. above, make the changes and then click the corresponding Set button.
