This page is for advanced users only; the table below lists various other options that'll enable extra features on your Sony PC4/5 camcorder. However we've not extensively tested these so we cannot guarantee that these will work, so use them at your own risk. Some features only work on a particular model, for example, a memorystick is not used with the PC4.

Fig 8. Register values for extra features on the Sony PC4/5 camcorder.

There’s two things that you'll have to do every time you change a register value, you’ll have to authorize the writing of the registers and re-check the checksum before writing the registers. This basically means that you’ll have to execute the following table if you’re willing to enable these extra features.
