Have RV Questions? Ask an RV Mechanic Online.
Hi, I am Mike, welcome. I'm reviewing your question.
Is this a BOSE?
See if this is the procedure on page 14 here, http://products.bose.com/pdf/customer_service/owners/cinemate_series2_og.pdf
the cover slides off.
Did that answer your question? If so, kindly leave me a positive rating, so I get credit. After all, you have already made the deposit. If you don't, the deposit you made will just sit there and I won't get my share of it.
Here is just 1 page, https://www.bose.com/en_us/support/article/replacing-the-remote-control-batteries.html
Did you get it open?
