Cant remember pin for vh-310 bluetooth head set how can i reset it

Try reseting,turn the phone off and back on,then reset the head set. Follow the manufacturers instructions for setting the unit in pairing mode

Call tech support and they can reset it for you.

Full procedure should be in the instruction manual under a likely heading of "Resetting PIN"
If you've lost the manual go to Sharps websitre and follow the usually easy steps to view your TV's manual online. It may also be possible to download and print it too.

The default password, as with most Bluetooth headsets, is 0000.

The head set is still set to the old phone, hold down the call control button until it starts flashing red/blue. then it will be ready for your new phone to find it. (remember if you didnt change it the password will be "0000"

Try 0000, It worked for me

Most Motorola bluetooths have a default passcode of 0000 and cannot be changed.

I just figured this out after having my blueset linked with my old phone. I couldn't remember my password for the life of me to connect it with my new phone. Finally I turned on my bluetooth headset and then held the call button for about ten seconds. After that I proceeded to search on my phone for the bluetooth and link it. The password is 0000. I hope that helps!

0000 is the pin
