It's the TAMA's user name we need. To find out the user name of your V3 TAMA, click on the first button where you see the hungry/happy hearts. Keep clicking to get the USER NAME. It will be five letters long at the most.
Just in case your TAMA's user name is SOCCE, here are two codes for you:
First one: 96690 36818
