1 Un screw all the screw on black panel, but must remember where each on goes, but Be careful not the two screws in side mouth pice which holding the pitch bend unit. 2. open the battery cover remove all the battery 3. Remove the 1/4 earphone nut, and all screws on the silver metal case. (Under the black plastic ), you don't need to remove any screws from the "key" side 4. Use something to pull the battery Cartridge sideway out from Main attachments, but not all the way out from the ewi case, because you can't, the plastic case structure will be in the way, 5. Use some flat pice metal like dinning knife insert in to between black and sliver metal to separate the two parts, start from the mouth pice end, once you open wide enough the battery cartridge can be remove from the case out. Now you can open the Ewi 4000s and see the two HX nuts that holds the strap mount, put some Nail polish on it before you tie them up.....Warning.. You must pull the battery cartage sideway out from its electric plugging mount before you are trying to separate the plastic and silver housing otherwise you will damage the circuit board. That was What I did to mine. Good luck and may God provide you wisdom for this.

You may need to do a factory reset. It sounds linke a transpose setting has been invoked. Read your manual under the word "transpose". A factory reset, if required, usually involves holding one or more buttons or keys down while turning on power and holding them until the reset is acknowledged.
