All of the battery adjustment on the Ijust S is done with a single button with no screen read out to see how it's set. It uses different colour lights and flash sequences to tell you how it is set. It's more complicated than simply looking at a screen to adjust the device how you like. A simple glance will tell you you are good to go.
With the flashing lights the setting may be more difficult to check or change, especially on a sunny day. Cheers.
