This guide will show you how to change the value of your POT (potentiometer). You will need to do this once you have installed a modchip. It helps the laser read backups and imports without getting dreaded DRE's (disc read errors). You will find the POT located on the board beneath the drive unit. If you don't know how to find it, follow the first part of this guide here

You will need a multimeter (preferably digital) in order to change the value of the POT. Although it is possible to change without one, it will be very difficult to get the settings right. The two multimeter testing points are marked in red circles on the picture. Once you have a reading, you will need to change that reading by turning the POT screw anti-clockwise. It is VERY sensitive, and the smallest movement could be the difference of 50 ohms, so you need to be patient. From what I understand, the gamecube laser was released with a reading of about 650 ohms and was designed to gradually decrease over time.

For those of you new to multimeters, you will need to set it like this
