Hi. My name is*****'m a camera repair technician with almost 30 years in the business and I'll be glad to help you with your question today.
Start with the reset button. With any luck, it will then pair up as it should. You may also need to re-install the device drivers. What type of computer are you using?
Just a note to see if I can be of any further assistance?
