Hi, I can't see what radio and CD player you have- so hard to tell how to connect them. Could you provide any info about this equipment at all- Brand, description, etc.?
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially and on a "...Bose wave radio with separate CD player...", proposed preliminary try would be to perform a RESET by removing the 9V backup battery for an extended period of time. This would be at a compartment at the bottom of the unit.
Please post back results / observations of the above once tried.
