HFBLU-CX1 BLUETOOTH HEADSET

Had the same problem. Paired fine with multiple devices (headset, computer, auto.) Then all of sudden BT will not connect. Cannot re-pair (unable to find device(s)). Had 1st phone replaced. Within about 6 months, the 2nd Dare did the same thing.

the problem seems to be the charging box. if the red light goes off relatively quickly after you place the bluetooth in the box then it is not gaining a charge. you have a warranty with this item that you can claim by following the instructions on the warranty card provided in the package.

go to your phone and turn on your blue tooth.that might be the problem.

I eventually found that you need to:
--hold the large button on the headset down for >5 secs to activate the headset.
--on your cellphone....set up the headset as a "Bluetooth" device
(password is usually 0000)
--then click on the large button on the headset to recieve a call.

The headset works fine....but I cannot fathom how anyone who never had a "Bluetooth" device would ever figure out how to do this.

But then again...I did ......didn't I?

Please make sure the bluetooth is in pairing mode, you know this when the unit is flashing red/blue at the same time. you can achieve this by first turning the unit completely off. once the unit is off then hold down the power button until you see the re/blue flashing light. then have your phone search for a new device again. if this does not work you can always take the battery out of your phone while it is still on (for about 5-10 seconds) so that it can reset. then try the process again.

headset won't pair with me phone and i have tried 0000 and 1234 and 12345

I was given this bluetooth after a buddy of mine could'nt figure it out. I figured out how to sync it by following that longer than 5 secs. idea that's posted here. I did'nt have a manual so I just put in "0000" and it worked! So try that...Good Luck. Thanx4Hating

I just glued them back together and wrapped black electrical tape around the glued  together section,no more breaking for me.

found it. it's 1234

how long have you had them and if it's less than 30 days exchange them i sold plantronics and had alot of returns every day so.....
