How to Pair BlueAnt Supertooth eHow

This is what I found:

BlueAnt Wireless Supertooth 3 Why Won my BlueAnt Pair

Disconnect the two devices from the speaker, turn off and on the speaker and pair and connect it with the new device.

On the iphone in bluetooth menu delete all soma speakers.
on the soma put it into bluetooth discovery mode
on the iphone wait till soma speaker shows up
select the soma speaker NOT the arrow on the right side
wait till the iphone reads 'connected'
if you are asked for a passcode use 0000

it arises commonly because most of bluetooths cannot support more than one device(if once connected they dont connect to other device) ....

Hello,
Thanks for using Supertooth.

do the pairing as explained below:


Your Supertooth BUDDY must be in pairing mode before searching from the
phone.

1. From OFF, press and hold the On/Off button for 10 secondes until the
Bluetooth Indicator turns blinking red/blue. The handsfree kit is now in
pairing mode.

2. While the handsfree kit is in pairing mode, access the Bluetooth menu
of your phone. Turn on the Bluetooth function and execute a Bluetooth
search. (See your phone's manual.)

3. When the phone displays the list of Bluetooth devices, select ST
BUDDY.

4. If the phone asks for the password/pin code, enter 0000 and press Ok.

5. The handsfree kit is now ready to use.

Best regards.

SUPERTOOTH

Step 1: Activate Pairing Mode on the Supertooth 3

Make sure the Supertooth 3 is turned off.
You can tell if the Supertooth 3 is on or off by looking at the light on the front. If the light is on or flashing, then the Supertooth 3 is on: turn it off by holding down the Multi-Function button (the green button) for about 5 seconds, until you hear the voice announce that the Supertooth 3 is powering down.
With the Supertooth 3 off, hold down the Multi-Function button for about 6 seconds, until the light on the front of the unit starts flashing red and blue.
The Supertooth 3 will now prompt you to select your language: press the Multi-Function button when you hear your language spoken.
The Supertooth 3 is now in pairing mode.


Step 2: Apple iPhone

Now you need to use your iPhone to search for Bluetooth devices:

Select Settings.
Select General.
Select Bluetooth.
Wait for your phone to search for devices, then select your BlueAnt device from the list.
If you are prompted for a PIN, enter 0000 (four zeros).
Select Connect.

Your BlueAnt device is now paired.

I had the same problem as you. I took the following steps to solve it.

- Powered off both devices.
- Turned on the Supertooth by holding the powerbutton until light alternates red/blue.
- Turned on phone, enabled bluetooth.
- Went to Connectivity->Bluetooth->(right)->options>"New paired Device".

It finally managed to pair the device.
Had to enter pincode (0000, which is default for all supertooths).

Hope it helps.

On your phone, make sure bluetooth is turned on (settings, general).

While your phone is in discovery mode, turn your bluetooth device on and put it in discovery mode (usually you have to hold the power button for 7-10 seconds).

Your phone will find the device, and you will be prompted to enter the devise's PIN number (often 0-0-0-0). Your phone should pair with the device then.
