(At Lunar 5 - Open the Sector B door) Look close at the blue display panel Enter the normal settings as stated in your room: Bottom left - 21 for oxygen top left - 78 for nitrogen and top right - 1 for CO2. (WT Gameboomers)

Hi linda,

You've set the lower left display to 21.
What numbers are the other two displays currently set at? As the combined total of all 3 displays cannot be more than 100, you may need to decrease the setting of the top right display first.

the other 2 displays has to be 78 and 1, but I find already the problem, its a bit difficult to click at the right arrow ( the arrows are very close together). anyway, thanks for helping.

Aha, glad you figured it out.
