Will using WWAN impact my battery life?

Yes. However, battery life is a complex calculation, based on a variety of factors that
include: software applications in use, wireless features in use (bluetooth, Wi-Fi, GPS),
exposure to extreme heat or cold, age of the batteries, and battery storage and charging
routines. Using the WWAN 3.75G feature requires power and that comes from the batteries
when the unit is not plugged into an electrical outlet.
Typically, your battery run times will be impacted less than 10% to as much as 20%,
depending on transmit and receive times, and standby time.

What operating systems does the Yuma 2 tablet support?
All Yuma 2 tablets have the Microsoft® Windows 7 Professional operating system.
How does the operating system language provisioning feature work?
When the Yuma 2 is turned on for the first time, the operating system prompts the user to select
one of 8 available languages:
English
Spanish
French
German
Italian
Portuguese (Brazil)
Korean
Japanese
Then, the Microsoft® Windows License agreement process also prompts the user to select one
of many languages available. This selection is different from the operating system of the Yuma
2 tablet computer itself. CHOOSING A LANGUAGE IS A ONE-TIME ACTION and
cannot be undone. Microsoft offers more than 30 languages for Microsoft supported programs,
compared to the operating system for the Yuma 2.
If a Yuma 2 has been set up in English, can it later be switched to another
language?
Choosing a language is a one-time action and cannot be re-done except by doing a complete
operating system restore from the system recovery partition.
What level of GPS accuracy can I expect with my Trimble Yuma 2?
In its current configurations, the Yuma 2 will collect at 2 to 4 meter accuracy. It contains an
integrated antenna, with automatic SBAS corrections. The accuracy may improve by attaching
an external GPS antenna, if the antenna has a better view of the sky than the Yuma 2 tablet.
What are SBAS corrections and how does the Trimble Yuma 2 use SBAS?
All Yuma 2 models have an integrated GPS receiver that supports SBAS (Satellite Based
Augmentation Systems) satellites under normal conditions. SBAS is an augmentation
technology for GPS, which calculates GPS integrity and correction data with RIMS (Ranging

http://www.trimble.com/rugged

93053 Rev. B

Page 7

and Integrity Monitoring Stations) on the ground and uses geostationary satellites (GEOs) to
broadcast GPS integrity and correction data to GPS users.
There are several compatible SBAS systems available around the world including:
WAAS (Wide Area Augmentation System) for North America
MSAS (Multi-Functional Satellite Augmentation System) for Asia
EGNOS (European Geostationary Navigation Overlay Service)
Can I use an external GPS antenna with my Yuma 2?
Yes, there is an accessory kit available that enables a direct connection with an external antenna.
(part number:ACCAA-312, Yuma 2 External GPS kit)
Can I use an external GPS Receiver with my Yuma 2?
Yes you can. Trimble GIS makes a Pro series receiver that connects easily to the Yuma 2.
However, please research the specifications and connection options prior to making model and
configuration assumptions for an external GPS receiver.
Is raw GPS data available?
Raw data output in the NMEA format is supported. The raw data stream can be used in external
applications that offer precision positioning, real-time kinematics (RTK) and attitude sensing.
What wireless connectivity options does the Yuma 2 support?
All Yuma 2 models have Bluetooth and Wi-Fi wireless technology. The CX and CLX models
are equipped with a 3.75G cellular modem for connecting to the Internet.
How can I use the Yuma 2 Wi-Fi capability?
Trimble Yuma 2 tablet computers have an integrated Wi-Fi wireless Local Area Network
(WLAN) radio that can be used to receive data anywhere within the range of a Wi-Fi access
point. A Wi-Fi connection can be used to connect to the Internet (at broadband speeds) through
an 802.11b, 802.11g or 802.11n access point.
NOTE: When there is an active connection to a Wi-Fi access point, power consumption
increases and the battery will discharge more rapidly, depending on factors such as:
proximity to the access point (more distance requires more energy)
total data sent and received over time (more data requires more energy)
ratio of upload and download activity (transmission, or upload, requires more energy)
How can I use the Bluetooth capability?
All standard versions of the Trimble Yuma 2 include an integrated Bluetooth radio to establish
cable-free connections to other Bluetooth devices that are within 10 meters.

http://www.trimble.com/rugged

93053 Rev. B

Page 8

Using a Bluetooth connection, you can communicate with other Bluetooth-enabled devices such
as mobile phones, desktop computers and more. You can also communicate with Bluetoothenabled peripheral devices instead of using USB connections.
NOTE: When there is an active connection to another Bluetooth device, power consumption
increases and the battery will discharge more rapidly. Individual usage patterns will vary by
device and the frequency of the Bluetooth communications.
What are the functions of the integrated digital camera?
All Trimble Yuma 2 tablet computers include a 5 megapixel integrated digital camera with an
LED flash and geo-tagging. The camera is accessed through an application that is pre-installed
with the operating system. The camera features a variety of shooting modes to make it easier to
capture images in different lighting conditions, and it can also record video with audio.
What are the power options for the Yuma 2?
The Yuma 2 ships with two standard rechargeable batteries. The standard batteries will provide
at least five (5) hours of operational time, depending on the features activated. The batteries are
internally rechargeable using the International AC Charging Kit that is included with the unit.
For workers who are doing extensive field readings and are not close to a source for energy
replenishment via an AC adapter or vehicle charger, Trimble offers the Extended Battery Set
accessory that doubles the operational time of the Yuma 2 between charges.
In the field, batteries can also be hot-swappable; that is the batteries can be changed out for new
ones while the unit is working. As long as there is some charge in at least one battery, users can
change out the other side, and then if needed change the second one as well.
What type of cable connections does the Yuma 2 support?
The Yuma 2 features two USB host ports and one HDMI port.
The Yuma 2 supports a Serial connection via the USB to Serial Adapter accessory.
The Yuma 2 supports an external GPS antenna with SMA connector via the SMA GPS Adapter
accessory. The adapter is included in the GPS Antenna Kit accessory.
Will the Yuma 2 support USB accessories?
Generally the answer is yes, for those accessories with device drivers that are compatible with
the Microsoft® Windows 7 Professional operating system. Users can add keyboards, printers,
monitoring devices, measurement instruments, barcode readers and RFID readers; almost
anything that can connect via USB.
What is in the Yuma 2 box?

What is important to know about projective capacitive touchscreens?
Capacitive touchscreens are very common in today’s tablet computers and smartphones. The
Yuma 2 has a capacitive touchscreen that is highly responsive to the touch of a finger, as well as
a capacitive stylus. Users can easily zoom into images or data (if the software used supports
dual touch user interface). The capacitive touchscreen is based upon the user being a conductor
to enable the touchscreen properties. If the user is using gloves, such as during very cold
weather, we recommend using gloves that are designed for capacitive touchscreens.
If I lose my stylus, can I use a non-Trimble stylus?
Yes, there are a wide variety of capacitive touch styluses available in the market place that work
well with the Yuma 2 tablet.
Do I have to use Trimble provided gloves for my touchscreen to work?
No, but you do need to use gloves designed for use on projective capacitive touchscreens.
How do I enable the accelerometer and electronic compass?
By default, the accelerometer and magnetometer are disabled on your tablet computer. To
enable these features, perform the following:
1. Tap Start > Control Panel > Location and Other Sensors.
2. On the STMicroelectronics 6-Axis, Accelerometer/Magnetometer Enabled box, tap
to enable or disable this feature.
3. Tap the Apply button to save changes.
