If you need to make some serious space, or just want to start from scratch, you can just delete everything you have saved. But, because this is such a drastic step, Delete Everything has now been moved to the Advanced Settings of the box. This is to help reduce the number of times this is being done by mistake.

To delete all recordings from your Horizon box

• Go to Settings > Advanced Settings > Horizon Box
• Select DELETE ALL RECORDINGS: Warning!

You will be warned, that this action will delete all recordings from your  box, so you need to be sure it is what you want to do. We know we’re stressing the point, but you’d be surprised.
