The SMARTlight function allows you to adjust the colour of the screen lighting as the day progresses. By default, this function is in automatic mode (the switch is in the On position). The e-reader then determines the optimal colour temperature according to the time of day (from neutral white in the morning to warmer shades in the evening). When automatic mode is off (the switch is in the Off position), you can manually select the lighting intensity.
The e-reader must be set to the correct time to ensure that the SMARTlight function works correctly in automatic mode. To set the time, activate “Automatic time synchronisation” (Settings - “Date/Time”) or set the time manually.
