Setting up Nintendo Wi-Fi Connection 
You will first need to establish a wireless Internet connection to use Nintendo Wi-Fi Connection. From the Top Menu, select “Nintendo WFC” and choose “Nintendo WFC Settings“ to configure the DS system. Please see the Nintendo Wi-Fi Connection instruction booklet, available at www.nintendo.com/consumer/ manuals, for directions on setting up your Nintendo DS.
*If you change the combination of your DS system and “Pokémon Mystery Dungeon: Explorers of Time,” you need to do the setup again to connect. Your roster of registered friends (P. 28) will also be deleted.
*Please note that if you choose to use your cell phone for e-mail notifications, standard text-messaging fees apply. Check with your carrier for additional info. Nintendo of America Inc. or Nintendo of Canada Ltd. has no responsibility or liability for such charges.
