I had not used my system for a 2 months and recently disconnected my batteries. I then tried to connect to my SmartBMV712. It would go to about 40%, then start over and go to 1%. Then it would say it is unable to connect and to input the code on the screen to pair with my phone. But there is no code displayed. When and where do you add this code? When the Bluetooth Pairing Request is displayed ("Smart BMV HQ..." would like to pair with your phone. Enter the code shown on...Do not do anything on SmartBMV HQ..."until pairing is complete)? I tried entering the PUK, but it has letters. I tried the pin and nothing. Seems I am locked out and can not pair. PS it is an iPhone SE
thank you
