To use the walkie talkie function properly, you should insure that you connect the bling jet, turn on message broadcast in the shortcut menu, add friends in your group and operate LIVALL APP with foreground status. Then you can go to shortcut menu to click the “Bling Jet Talking” submenu and set up a new talking objective or group. After you select your intercom friend, return to the homepage. Click the Start button to start riding and hold the intercom key on the bling jet to start a intercom conversation.
