Replacing a disk
Replacing a disk on a PT6500 device is a fairly straightforward process that requires only basic skill with a screwdriver. You will need a small-diameter Phillips screwdriver. Make sure the device is shut down and unpowered.

Replacing RAM

- Place the device with the screen facing downwards, and remove the four screws that hold the back cover in place:
