2.1.19 Ambient Light sensor
The light sensor measures the environmental light and allows the Tellus to
automatically adapt the backlight of the display. This will optimise power
consumption and increase battery life.
Select the Light Sensor on_off symbol on the desktop to switch on or off this
utility.
2.1.20 Microphone array
The Tellus has an integrated microphone array of 2 microphones. The internal
microphones will be switched off as soon as an external microphone is
connected.
2.1.21 Power ON/OFF switch
Press the Power ON switch shortly to power up the Tellus. The power indicator
will turn on.
When turned on, the Tellus can be put into stand by mode by pressing the on/off
switch shortly.
In stand by mode all system functions are turned off. Power to memory is still
on, maintaining data in programs that were running before entering the Stand by
mode. Power consumption is now very low in favour of a long battery run time.
Resuming from stand by mode can be done by pressing the Power Button
shortly. After approximately 3 seconds the Tellus will be ready to be used again.
Switch users can use switch 1 or switch 2 to resume from Stand by mode.
