In some cases people have figured this out by accident, and I wish the instructions in the sheet that shipped with the units was more detailed – but here’s a little video showing exactly what to do to change the audio volume level on your Dragon Door Isochain – I’ve also written it out below the video in case you’re not up for watching a video. Also, the Isochain Preorder is about to ship out, but there’s still time to get in on the deal (but not for long).

Step 3: After the number (which will be something between 0 and 5) appears on the screen, use the up-down arrows to adjust the volume to your liking. I would suggest keeping it at at least “3”. If you put it to zero then it will be silent which will negate a lot of the benefits of having the audio sounds (so that you don’t crane around trying to see the screen during an exercise… OUCH!).
