The colour schemes are:
Indoor scheme – for everyday use
Alhambra and Arcade schemes – alternative colour schemes for everyday use
Outdoor scheme – for very bright conditions, where you need as much contrast as possible
Night scheme – for measuring under very dark conditions, where is needed night vision
For each colour scheme, you can select the optimum choice of brightness for the traffic light
(for example, High for Outdoor in bright light conditions and Low for Night in dark conditions)
and whether to have backlight on the keyboard. In very bright lighting conditions you will not
be able to see the backlight, set it to Off to save some power.
A link is also provided in Display Settings to adjust the touch-sensitive screen. Tap Adjust
