Welcome to the forum. Where are you from?
The buttons/instructions are different depending on whether you have navigation or not. If you type "opening ceremony" or "greeting" in the search bar above, it will bring up links to instructions, adobe (.pdf) files and youtube videos for this. Be aware that not every bike will respond to the instructions. Some just refuse to comply.
Based on this and your other question, I am guessing you do not have an owner's manual. You should look at trying to find one.
