Introduction

This is just a chip identification of the Logitech S-715i speaker and does not contain the full teardown process as I took this apart quite a while ago. Although there is a remote control for this unit, I was unable to find it so therefore it would not be part of this teardown.

This teardown may be downloaded at the end of this guide.

This teardown is not a repair guide. To repair your Logitech S-715i, use our service manual.
