You first must register your radio on myradio.gracedigital.com
To register you will need to do the following:
1) You will need to get a fresh registration key from your radio. (this key changes often, so you will need to enter it on the website right away) Go into your 'settings' menus and select 'register' and write down the key (code) that is provided
2) Go to myradio.gracedigital.com and enter in your registration key and create an account. Note, this website is not optimized for tablets or phones, but may work if you use the device in landscape mode.
3) Then on the side or the top of the web page you will see ‘Pandora’. Enter in the email address you used with Pandora and password. If you don’t currently have a Pandora account you can do that at www.pandora.com or on our web site. If you have trouble linking your Pandora account, make sure that there are not any non-alphanumeric characters in your password. Symbols will block our site from linking your account.
4) Go back to your radio and unplug it then plug it back in. Then turn it on. You will now have a choice under the main menu titled 'personal radio'. Pandora will be in that menu item. Click on Pandora and you will now be able to see your Pandora radio stations on your radio. You can now create stations on your radio or on the Pandora web site. To remove Pandora stations, you need to do that at Pandora.com
