Before you start, make sure that:
a) the Bluetooth headset is fully charged, switched on and within range of the phone (not more than 1 metre away)
b) Bluetooth is activated in the phone (for more information, see the phone's user's guide)

The first time you switch on your headset it will automatically go into pairing mode. The next time you turn on the Bluetooth Headset, and perhaps wish to pair the headset with another Bluetooth device, you must set the headset in pairing mode manually.

To pair the headset in automatic pairing mode (this only works the very first time you turn on the headset):
1. To switch on the headset, press and hold the Call handling button for 5 seconds, until you hear a beep. The Call handling button is on the front of the headset.
2. The indicator light will now flash red and green, which indicates that the headset is in "Pairing mode".
3. In the phone, you now have to add the headset to the phone's list of Bluetooth devices. For detailed instructions, click on Product Information/Getting started in the left-hand navigation menu, or use the phone's user's guide.
4. You must enter a Bluetooth passkey in the phone. The default passkey is 0000.

To pair the headset in manual pairing mode:
1. Press both VOLUME BUTTONS, (+) and (-), at the same time for 5 seconds until you hear a beep.
2. The indicator light will now flash red and green, which indicates that the headset is in “Pairing mode”.
3. In the phone, you must now add the headset to the phone's list of Bluetooth devices. For detailed instructions, see "Getting started", or use the phone's user's guide.
4. You must enter a Bluetooth passkey in the phone. The default passkey is 0000.

Pairing (sometimes also called adding or bonding) enables two Bluetooth devices, for example a headset and a phone, to connect to each other and work together whenever they are switched on and within range of each other.

Before you can start using your Bluetooth Headset with another Bluetooth device, for example a phone, the two devices have to be paired with each other. You only need to pair the two devices once, and normally there's no need to repeat this procedure. But if you want to use your headset with, for example, another phone, you must pair the headset with the new phone.

It takes about 2 hours to fully charge the Bluetooth Headset. If you haven’t used the headset for a while, the battery could have a reduced capacity and may need fully recharging more than once.

Note: Before you start using your Bluetooth Headset, you must charge it for approximately 8 hours to reach the battery's maximum capacity.

Insert your fingernail into the notch at the bottom of the headset, and pull off the metallic cover. Underneath you will find the regulatory information.

When you pair the Bluetooth Headset with a phone, the headset is added to the phone's list of paired Bluetooth devices. When you subsequently turn the headset on, the phone will automatically recognise the headset. If you've paired the phone with more than one Bluetooth device, you must choose which device you want to connect your phone to from the phone's list of Bluetooth devices.

If you can't answer a call using the headset, check that:
a) the headset is fully charged, switched on and within range of the phone (not more than 1 metre away)
b) Bluetooth is turned on in the phone (for more information, see the phone's user's guide)
c) the headset is correctly paired with your phone

Note: For detailed instructions on how to pair the headset with a phone (most Sony Ericsson phones), click on Product Information/Getting started in the left-hand navigation menu, or use the phone's user's guide.

The Bluetooth Headset will stay in pairing mode for 10 minutes. If you don't pair the headset with another device during these 10 minutes, the headset will automatically switch off.

If this happens you must turn on the headset, set it in pairing mode and start pairing again.

Yes.

Remove the earhook from the headset and flip it to make it fit the other ear. Then put it back on and make sure it's attached to the headset correctly. For further instructions, please refer to the User Guide.

You may need to charge the battery.

Check the indicator light, which is on the front of the headset next to the call handling button. If the indicator light flashes red, you must charge the battery.
