Yes, it means that when the direction of human sight is consistent with the direction of projection arm, it is positive, otherwise it is opposite. This is

designed according to the ergonomic way of thinking.

Please keep in mind that the alarm clock must not use high-capacity alkaline batteries, please use ordinary carbon batteries, otherwise some buyers may say garbled, because high-capacity batteries are easy to burn out the circuit board!

If you are looking for a model that can be continuously projected and has high quality and low price, it is this one!

When the Projection Clock is 2 meters away from the receiving wall or ceiling, the height of the projected font is about 20cm.
