When I first turn on my system after work, the remote is dead. Until I take the battery cover off and remove and replace one, the same battery. Or maybe I will just rotate one or both of them to get the contacts fresh. Then it works fine. These are new alkaline AAA's. Tried another set of new ones, tried scraping the contacts with a sharp knife and also all 4 battery ends. Anyone else experience this with this remote? Perhaps switch to lithium AAA's?
