Light Sensor
All units have an ambient light sensor located on the front
of the Mesa 3 in the upper-right corner. The light sensor
dynamically adjusts the backlight on the display.
You can disable this process and manually control the
display brightness if you prefer. Go to the Start menu
and select Settings > System > Display. Turn off Change
brightness automatically when lighting changes and tap
Apply. To manually adjust the display backlight, tap on
the battery icon at the bottom of the desktop screen. The
display backlight brightness can easily be toggled up or
down in 25% increments from 0% to 100% by tapping the
percent tile (see the sun icon).
SD Cards
The Mesa 3 has a slot for a micro SD card located in the
battery compartment. The card slot and exible card
holder are designed to hold the card securely in place so it
will not come out or disconnect if the tablet is dropped. To
insert or remove a card, follow these steps:
1. Power off the tablet.
2. Remove the battery door as outlined in chapter 1.
