How do I bring up the interface?

To bring up the interface on BlackBerry devices, dial the default key sequence and press SEND. The default key sequence is #12345*

After you press SEND and are on the call screen, you can wait for the interface to appear or press the END key to speed up the process.

You can change which numbers are used (i.e. 12345) inside the interface by going to Menu > Change PIN. If you change the PIN to 22222, it will change the key sequence to #22222*.
