Thank you for your post, and welcome to the community!
Is your system the Wave SoundTouch Music System IV (pictured below)?
If your system does not have the bottom pedestal attachment, you will not be able to utilize SoundTouch and/or Bluetooth capabilities (without an additional adapter).
If you are using a Wave SoundTouch Music System IV, please see the 'Setup and Use' section of our support page found HERE. There are helpful articles that will provide steps for connecting Bluetooth devices, and using the SoundTouch app.
