My Vejo flashes orange or red - what does that mean?

When the LED lamp of the Vejo flashes orange or red, the Vejo needs to be charged. The orange light shows a critical battery condition where the battery power is no longer able to mix another blend.

If you start using the Vejo in orange light anyway, it stops after a few seconds because the battery is not charged enough. After recharging the Vejo, mixing the blends works as usual again.
