I can no longer access my EX2 - it does not appears as a shared device on either of my Macs nor is it any longer accessible my iOS devices. Now the top light is red. Please provide instructions or an email address I can write to in order to arrange to return the device for repair or, if necessary, data recovery.
The following link contains detailed instructions related to submitting an RMA:
The data within the unit will be destroyed once received for customer protection. As such, if data recovery is a concern then it should be carried before requesting a product replacement (RMA).
Thank you for the information.
