Laser Adjustments

• P581: PLL
• P501: E/F Balance
• P502: Tracking Gain
• P503: Tracking Offset

Replacement Laser

Left: The correct 10-pin laser. Right: The incorrect 8-pin laser. The silver plate covers half of the photo diode array, but you can still see 5 visible connections on the leftmost laser, and 4 visible on the right.

The CDX / MultiMega consoles use the Sanyo SF-C93 laser.

Warning: There are two versions of the SF-C93, one version has a photodiode array with 10 pins, and one version with 8 pins. The correct replacement for the CDX is the 10-pin version.
