Victor WM-J80 Wireless Microphone with ON/OFF Switch. - Brand: Victor - Model: WM-J80 - Type: Wireless Microphone - Switch: ON/OFF Switch - B-band 30-channel selectable Thank you for viewing. I obtained this on Yahoo Auctions, but although it powers on, it wouldn't receive with my receiver (Victor WT-892-B) (It was supposed to be in working condition, but I was disappointed that they didn't accept a return or refund.). This is an auction for the main unit only, and the rechargeable batteries in the photo are not included. ...So, if anyone needs it, please consider it.
