Chapter 2 Standard Features 11
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

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 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.
CAUTION: The Mesa 3 is not sealed against water and
dust when the battery pack and battery door are not

internal battery, this caution does not apply. You can
safely remove the removable battery while the unit is
running.
3. Remove the battery pack by pulling up on the black tab
on the battery pack.
4. An image on the battery compartment label shows the
correct location and orientation for the SD card (slot on

Sensors
Compass, Accelerometer, and Gyroscope
The Mesa 3 has a built-in compass and accelerometer.
The accelerometer assists the compass in determining
direction, even when the device is not resting at. The
gyroscope senses change in angular motion. The compass,
accelerometer, and gyroscope can also be used by other
user applications.
Compass Calibration
The compass has been factory calibrated. Periodic user
calibrations help the compass function in the environment
the Mesa 3 is being used in.
1. Open an app that uses the compass.
2. Move the Mesa 3 around in the air so that it is oriented
in different directions and angles. An effective way to
assure this is properly done is to move the Mesa 3 back
and forth in a sideways gure 8 for approximately 30
seconds.
Bluetooth®Wireless Communication
The Mesa 3 has built-in Bluetooth®wireless technology,
allowing you to connect it to other wireless devices with
Bluetooth technology.
Creating a Partnership/Pairing a Bluetooth Device
To create a partnership between the Mesa 3 and another
device with Bluetooth technology:
1. Turn both devices on.
2. Place them within a few feet of each other. (The Mesa
has long range Bluetooth, but the other device might
not.)

14 Mesa 3 Rugged Tablet Owner’s Manual
3. Make Bluetooth discoverable on both devices. Bluetooth
on the Mesa 3 is off by default. To activate it, open the
Action Center and press and hold the Bluetooth icon.
Select Go to settings.
4. In the Bluetooth settings screen, you should see a list of
all Bluetooth devices within range. Tap on the name of
the device in the list you would like to pair with, then
tap Pair. If prompted, enter the PIN or pass code of
the paired device. You should now be paired with the
device.
Note: If Bluetooth is on and the tablet enters sleep or
hibernate mode, Bluetooth turns off to save battery power.
The connection is resumed once it powers back on.
Wi-Fi Wireless Networking
The Mesa 3 has built-in Wi-Fi wireless networking to connect
to the internet or an ofce network.
Connecting to a Wi-Fi Network
To use Wi-Fi, you need to be in range of a Wi-Fi access
point to make a connection. When Wi-Fi is turned on (the
default), the Mesa 3 automatically starts scanning the area
for available Wi-Fi networks.
From the Action Center, click and hold the Wi-Fi network
icon, then select go to settings. A list of available networks
is shown. Select the network you want to use and enter
the network security key. The Mesa 3 remembers the Wi-Fi
network connections created.
Wi-Fi can be turned off and on and settings can be
managed from this set up screen.

Chapter 2 Standard Features 15
Power Management
The Mesa 3 runs on battery power, using a rechargeable, Li-
Ion battery pack. A non-removable, internal battery pack is
an option.
Charging the Battery Pack(s)
For instructions on how to insert and charge the removable
battery pack, refer to Chapter 1, Install the Battery Pack.
For tablets that have both a removable battery pack and
an optional internal battery pack, the intelligent internal
battery charging circuit rst charges the battery pack with
the least amount of energy. When this battery pack comes
to the same level as the other battery pack, then both
battery packs are charged at the same time until they are
both fully charged.
Battery packs are charged most efciently at room
temperature (68°F or 20°C). They will not charge if it is too
hot or too cold.
CAUTION: Only use the battery charger that came with your
Mesa 3 tablet. The Mesa 3 requires a 30W or higher power
supply with a 12V output to power the tablet and charge
the batteries at the same time within the specied 4-6 hour
time frame. Anything less will not allow the tablet to operate
as specied.
Battery Status and Management
To nd out how much battery life you have left, tap on
the battery icon at the bottom of the desktop screen. The
amount of charge left as a percent and the status of each
battery is shown. The cumulative amount of battery life left
for installed batteries and the approximate amount of time
battery power will last is also shown. The amount of time left
varies depending on what you are doing with the unit.
Battery Life
Battery life on a full charge can be 12 hours or more. This
varies depending on whether or not you also have an
optional internal battery, the applications used, backlight
usage, and radio usage. The optional internal battery adds
5-6 extra hours of battery life.
!

16 Mesa 3 Rugged Tablet Owner’s Manual
The shelf life for battery packs is about one year. The battery
packs should be recharged at least once per year. This
prevents the battery packs from discharging to a level that
might damage the batteries. Battery packs that are not
recharged at least every year, could fail to work or may
have reduced capacity. Battery packs typically last 1,000 to
3,000 charging cycles.
CAUTION: Only use batteries designed for the Mesa 3 from
an approved vendor. Use of non-approved batteries may
void your product warranty. The Mesa 3 must be returned to
the factory for replacement of the optional internal battery,
although the internal battery pack is designed to last the
life of the tablet.
CAUTION: The unit is not designed to run on external power
without a battery installed. Doing so can damage internal
components of your unit and void the warranty.
Powering Off the Mesa 3
Short-term Storage
When you plug the tablet into the wall charger that comes
with it, the batteries are prevented from being overcharged.
Charge the Mesa 3 to 100% then power it off:
1. Press and hold the power button for 2-3 seconds.
2. A message is shown asking you to slide the screen down
to shut down your device.
Long-term Storage
To power off the Mesa 3 for long-term storage, follow these
steps:
1. Power off the Mesa 3 as described in the previous
section, Short-term Storage.
2. Press and hold the power button for 20 seconds. This
disconnects the batteries from the system.
3. Take out the removable battery and store it in a cool,
dry location.
4. When you are ready to power on the Mesa 3, replace
the battery pack. Plug in the AC wall charger and
connect it to the Mesa 3 BEFORE you power it on.
