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).
Connector Ports
The Mesa 3 has a 12 VDC power input jack, USB 3.0 Host
type A, and a 3.5mm audio jack.
Connector Protector
The connector protector is removable and replaceable. To
remove it, pull it out of the ports, then gently pull the curved
rubber retainers out of the holes they are in. Replace it by
inserting the curved rubber retainers back into the holes.
See your sales representative if you need a new one.
Note: The connector protector is not required to maintain
the seal of the connectors or the tablet. The connector
protector is intended as a port dust cover.
SD Cards
The Mesa 3 has a slot for a micro SD card located in the
battery compartment. The card slot and flexible 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.
!
CAUTION: The Mesa 3 is not sealed against water and
dust when the battery pack and battery door are not
installed properly.
