Gemz Friends A) Adding Friends: When you sync your Gemz to add friends with the device, you are now able to do the following: send and receive secret coded messages with each other and interact with each other online after signing up at bffgemz.com! To add friends, do the following: 1. Make sure your device is turned on. 2. You and your friend must each press the user button at the same time and hold for three seconds. Once synced, the button will light up, letting you know © 2011 eMotion Group Inc. 11 that the Gemz are ready to send and receive messages to each other. The color that the light glows corresponds with the friend you’ve just added. Note: Your Gemz allows you to add up to 8 friends. You can add up to 12 friends total by redeeming some of your GPA. For more info, see 7. Girl Power Average (GPA). 3. To become friends online, just plug your Gemz into a computer, log in to your bffgemz.com account, and the rest is magic.
