you need to press and hold the on button on the headset, until the blue light stays on, then it will be in pairing mode. As soon as the headset is paired the blue light will go off and flash periodically. To turn off the headset press and hold button for about 3 seconds, it will flash 3 times then let go and it will turn off.

I had the same poroblem. I turned the phone off and then restarted it. That worked for me. Try to make a phone call and see if you can hear it on the Bluetooth.

Bluetooth Troubleshooting: Phones & Headsets

Problem #1: Headset and phone are turned on, but you don't hear anything in the headset, i.e., there is no dial tone.
Action #1: Make sure your phone is Bluetooth-capable. If it is not: A. Buy a new Bluetooth-capable phone. B. Purchase a Bluetooth adapter for your non-Bluetooth phone. The adapter will allow your phone to interact with a Bluetooth headset.

Problem #2:
It's a Bluetooth-capable phone and Bluetooth headset, both are turned on, but you still don't hear anything.
Action #2: Make sure your phone, headset, and, if necessary, adapter are fully charged before attempting to synch the Bluetooth connection between the two devices - in many cases a blinking blue light will indicate the headset is charged.

Problem #3:
Everything is charged, but still not working.
Action #3:Before two Bluetooth-enabled devices can communicate with each other, they need to be initially synched up to each other - also referred to as linking or pairing.
A. Find "Communications" or "Connections" on your phone's menu screen and explore within to locate "New" or "Bluetooth."
B. Push the main button on the headset until the light shines solid blue and is NOT blinking. C. Select Bluetooth on phone menu. Within Bluetooth you may need to select and highlight "Devices" or "Find Devices" (depending on where you are, there may be other Bluetooth devices available).
D. While the headset light is solid blue, open the Bluetooth link (or Find Devices) on your phone's menu screen and scroll through until you locate the headset you wish to synch up to. Your phone will automatically begin searching for Bluetooth devices within 30 feet of itself.
E. After a short period of time, your menu screen should say "connected" or "devices paired". Make sure you click or select the device name to finalize the connection. If you have successfully paired the two devices, you will hear a dial tone in the headset. Congratulations! You've joined the Bluetooth world.

Note: After a couple of minutes showing solid blue, the light on the headset will start blinking; you want to pair up the phone and headset while the light is still unblinking. This is important. If the light starts blinking before you can complete the connection, you will need to turn the headset off and on and start over.
Problem #4:
You've followed all the instructions in this guide, and your Bluetooth connection is still not functioning properly.
Action #4: Take out your manual and carefully reread the section on synching up Bluetooth devices. If you still can't get things properly connected, we suggest you call the manufacturer regarding this issue.

just try it yourself:
go to the BT section on your phone.
press and hold the power button on your headset.(discoverable mode)
select the "find device" on your phone.
it should work itself out from there.

hold your finger on the call button on your blutooth device for around 6-10 seconds, this should make a couple of lights flash, when it does this it is active and ready to pair uo, then search, it will ask you for a code, usually they are generic and are prob the following 1234-12345-1111-11111-0000-00000-5555-55555 eiter one of these should work
