The passkey for your headset is hardcoded to '0000' (four zeros).
If it fails to pair with your phone, turn it off. Then, press the PWR button for some 4 seconds, until its indicator light is steadily lit. It is in pairing mode now. Then, make your phone's bluetooth application search for new devices. After a little while, the HBM-760 should appear on-screen. Select it and make it connect. If a pairing code (or PIN, or passkey) is requested, enter '0000' (four zeros). If the pairing process is successful, your headset should enter the stand-by mode.
Anyway, if its user guide happens to be missing, you can download it from this location.
Hope you are able to sort your problems out soon.

Turn it on by holding the power button for four seconds, Then go to your phones bluetooth setup screen, search for new devices, and pair it. The blue led on the HBM-760 will turn solid blue during pairing. It is always discoverable. The default passkey is 0000. Hope this helps.
Good luck and please rate 4 thumbs for the free answer

There is not a manual for your HBM-760 online at the present time that I can send you a link to. However, if you need to pair your headset, here are the instructions:

To pair the headset:

With the power OFF press and hold the "call button", the actual bluetooth symbol on the front for 7 seconds. You will see a solid blue light, this will then now be in pairing mode. The passkey is 0000 (four zeros)

Again, there is not currently an online manual for your HBM-760. I'll notify you when there is.

If you found this information helpful, please give me a big-thumbs up when you rate my answer. Thanks!

Go into your phone and under your bluetooth settings delete your headset profile. You can now just go through the pairing procedure again and your phone should find the headset and you can click yes pair with this device(headset) and just finnish you pairing. Also make sure you didn't turn your bluetooth power off on your phone by accident.

It sounds as if the device is not paired with your Chocolate. Press and hold the button on the face of the HBM-710 headset for approximately five seconds, or until the light comes on and stays on steadily, then discover the device with your handset's Bluetooth screen. Once it shows up in the list of devices, select in and pair it with your phone.

Turn it on by holding the power button for four seconds, Then go to your phones bluetooth setup screen, search for new devices, and pair it. The blue led on the HBM-760 will turn solid blue during pairing. It is always discoverable. The default passkey is 0000. Hope this helps.

The pin is 0000.
