HI GUYS I JUST BOUGHT A HL TIGER I TANK I LOVE IT BUT I HAVE ONE QUESTION.IT STATES IT HAS Six groups of automotive demonstration function and auto-programming function.WHAT DOES THIS MEAN AND HOW DO YOU USE IT??? THE INSTRUCTIONS DON TELL YOU UNLESS ITS IN CHINIZE..

It means you bought a Non smoke and sound tank.

I could never understand the instructions but apparently you press a button, run through a series of movements the press another button. Then when you press another button it'll repeat the movements you've just done.
