To switch Altos off, press and hold the button until the display turns off.
Usage recommendations
● On a single battery charge, Altos works for approximately six months. Charge Altos
timely to stay informed of the air composition changes.
● Recommended operating temperature range is 0...50℃. At lower temperatures, the
device’s sensors might perform incorrectly. It might take some time to get back to normal
work if the device stays in the cold for a while and then is brought to a warm place.
● To ensure a stable Bluetooth connection, the distance between your phone and your
Altos should be less than 10 meters.
