Stolen from another forum, and user Handley, after Googling "GL1800 Opening Ceremony". Not verified.
CUSTOM PROGRAMMING THE GL1800'S OPENING CEREMONY
(Note: "Press" means 'press and release'.)
1. Turn ignition key to ON or ACC, and wait for the normal screen display after the opening ceremony.
2. Press (press and release) the MODE button three times.
3. Simultaneously 'press and hold' the TRIP and DISP buttons for atleast two full seconds, and then release.
4. Press the MODE button.
5. Press the DISP button. You should now see the word "SPECIAL!". If not, turn OFF the ignition key, and start all over.
6. Press the TRIP button.
7. At the prompt "Change OK?", press the MODE button.
8. You should now see a 12-character line, with the cursor at the left end. Use the TRIP button to cycle through the available characters until you find the one you want (letters, numbers, blank, and some others).
Note: You cannot back up when cycling through the characters! If you pass the one you want, you'll have to cycle around to the desired character again.
9. When the desired character appears, press the DISP button to move the cursor to the next space to the right. The cursor moves only to the right, and then wraps from the right end back to the left end.
10. When the desired 12 characters have been selected, press the MODE button to store the selected characters into memory.
Now turn the ignition key to OFF while watching the display screen. You should see the words "SEE YOU!", with your 12-character line just underneath. When you turn the ignition key to ON or ACC, you should see "HELLO" and your 12 character line, and then a message saying "Welcome to the Gold Wing World".
