I've tried everything, but the Alto Clair 2 set still can't connect / reconnect, what should I do?
Devices should auto-connect when you turn them back on. If not, unplug the dongle from your PC, and then plug it back in. Or, select “Avantree AH6-P on your smartphone/tablet.
If your Alto Clair 2 set still can't connect, please follow the instructions below to factory reset both the AH6P wireless headphone and the DG10 USB dongle.
