Enable Keypad

If you get a message saying the  "Keypad is locked", you have 2 options to unlock it.

1. Turn the radio off, then on again - the keypad will be unlocked for 15 seconds on radio startup,
2. Use the Keypad to unlock the Keypad. This is done by pressing the Green button, then the * button.  Once done, you should see a message on the screen saying "Keypad Unlocked"
