How do I adjust the brightness on the display?

You can adjust the brightness of the display on the unit by pressing the Fan Speed button and On/
Standby button simultaneously. Keep holding the On/Standby button and tap the Fan Speed button to
adjust brightness. If the brightness is at the lowest level, it will increase by one level. If it’s at the highest level, it will decrease by one level.

You can also adjust the brightness using the Blueair app.
