The Motion Tablet PC Ambient Light Sensor (ALS), located on the front panel, detects light in the environment. When enabled, it adjusts the display brightness to changing light conditions. ALS maintains display viewability and can increase battery life as the system optimizes the display backlight in different lighting conditions, thus reducing power consumption whenever lighting conditions allow.

NOTE: For optimal battery life benefits and viewability, we recommend that you set the brightness slider to the mid-point or slightly above or below mid-point. If you set the slider higher than this, you lose some of the battery-saving benefits, while gaining minimal improvement in viewability.

To set the display to a fixed level (ALS is off):

1.Open the Motion Dashboard.

2.Under Display, tap the radio button beside Fixed.

3.Move the slider until the backlight on the Tablet PC display is at the desired level. The system will keep the

same brightness level at all times; that is, it will not adjust the display brightness in changing ambient lighting. This may sacrifice viewabil- ity

NOTE: In low-light conditions, the “Fixed” brightness setting may keep the display brighter than is needed for viewability. Keeping the brightness always at the same level may also use more battery power than necessary.

To set the display so that the system adjusts the brightness to the desired level under changing lighting conditions while maintaining viewability (ALS is on):

1.Open the Motion Dashboard.

2.Under Display, tap the radio button beside Dynamic.

3.Move the slider until the backlight on the Tablet PC display is at the desired level. The system will automatically adjust the display brightness in changing ambient lighting conditions.

NOTE: In low-light conditions, the “Dynamic” brightness setting keeps the brightness at an optimal level for viewability. It dims the display, as appropriate, which conserves battery power.

To turn the display off:

1.Open the Motion Dashboard.

2.Tap Off.

3.To turn the display back on, wave your pen over the display or press any key on the keyboard.
