I’m not familiar with the operational functions of that model earpiece, but... Bluetooth earpieces need to be recognized and also the phone needs to be set for recognizing devices, so I would just recommend going over the steps of both the phone and the earpiece for setup.

I am currently using the LG chocolate and I cannot seem to connect to my bluetooth motorolla HS850. Both units are functionaly fine, I have tried on 3 different LG chocolate phones and none seem to find my bluetooth device..... please help.
