I have a small white device 1-7/8 x 5-7/8 inch that activates remote house-bells with the following data: FCC ID: BJ4-61WDB57ATX CANADA: 1731 102 911 DESA SPECIALTY PRODUCTS Bowling Green, KY 2003 SL-6157-A-TX 390-6157XX-TX1A The reset black button make the bells work. The main bell (next to your device, which used to activate it) still works but your product does not. I would like to repair if possible OR buy a new one again. Thank you very much Zoran Balmas RZBK@mac.com
