I cannot reiterate this more clearly: If the HAs are locked by a code, SmartFit will ask for it the first time and it will refuse to continue until you provide a correct code.
Just make sure that:
- HAs are properly rebooted by introducing them into the charger and taking them out after 5 seconds.
- There isn’t any other bluetooth or accessory connection (remote controller, TV link or whatever).
You won’t be knowing if your HAs are locked until you get SmartFit to connect to them. The only secretive thing about the PIN code is the code itself.
