How do you take the front plate off a Sennheiser RS-120 charging cradle? The covering on the RCA male jack wire to the cradle has decomposed and needs replacement. Easy to do if you can get inside the box. Doing so is the puzzlement.>
First remove the two small screws that are visible on the back panel. Then carefully pry apart the front grey panel from the black rear panel. The plastic is designed to clip together very tightly. Use a credit card or blunt knife. The bottom should come free first, as the top hooks into place. There are no other screws.
