INTRODUCTION
Thank you for acquiring the latest addition to DT Research’s line of mobile tablets— the DT398.
Featuring an IP65-rated, slim yet robust enclosure, the two-pound DT398 with 9.7” TFT display is
powered by the Intel® Celeron® or Core™ i dual core processor, offering optimal combinations of
performance and power savings. An external battery expansion option provides approximately 3-4
hours of additional battery operation for up to eight hours of mobile usage.
The DT398 is available with Windows® Embedded Standard 7, Windows® 7 Pro or Linux operating
systems. Each software operating system features web browser, client/server computing software,
media player, accessories, and applications support.

Power/Battery LED Status:
Blue indicates the battery is 25% to 100% charged
Blinking blue indicates the battery is charging
Orange indicates that the battery is between 11% to 25%
Blinking orange indicates that the battery is below 10%
Blinking blue and orange alternately indicates the battery is being warmed up.
Do not unplug the AC/DC adapter.
Precautions
Always exercise care when operating and handling the DT398.
Do NOT apply excessive pressure to the display screen.
We recommend using the Stylus provided to keep the screen clean.
Avoid prolonged exposure of the display panel to any strong heat source. Wherever possible, the DT398
should face away from direct light to reduce glare.
If the AC-DC power adapter is used to recharge or power the device, do NOT use any AC-DC adapter other
than the one provided with the device or acquired from the manufacturer or its partners.
In the unlikely event that smoke, abnormal noise, or strange odor is present, immediately power off the DT398
and disconnect all power sources. Report the problem to your device provider immediately.
Never attempt to disassemble the DT398, as this will void the warranty.
The DT398 internal battery is designed for wide temperature usage. Please do not use it for other tablet
models.
(The wide temperature design is not applicable for external batteries.)
THE DT398
Basic Features
The DT398 tablet integrates a bright and responsive touch display, 1 USB port, and embedded networking
elements such as 3G. The DT398 is complemented by a suite of accessories, including battery expansion,
docking cradles, and wall/ vehicle mount cradles, for a comprehensive user experience.

OPERATION
Internal Battery
Warning!
The Internal battery pack should only be replaced by an authorized DT Research service representative. Please
contact your product and/or service provider for internal battery replacement service.
Powering ON and OFF
To activate the DT398, push and quickly release the Power Button. The display will come on in a few seconds.
To put the DT398 in Standby mode, push and quickly release the Power Button. To turn the DT398 off for
extended storage, power off the device safely using any software function that “shuts down computer” provided
in the software operating system.
NOTE:
The battery packs shipped with your device may be low in power—please use the AC-DC adapter
with the DT398 when setting up the device for the first time to fully charge the internal battery pack.
You may charge the external battery pack with it attached to the DT398, or with the optional external
battery charger kit.
NOTE:
When the battery pack(s) is (are) charging, the blue-colored Battery LED should blink slowly. If
plugging in the AC-DC adapter does not trigger this blinking activity and the LED stays dark, the
battery pack(s) may have been drained substantially. Try unplugging/ replugging the AC-DC adapter
to the DT398 a few times to activate the charging process.
NOTE:
To conserve power, use (push and quick release) the Power Button to put the device in “Standby”
mode while not in use. Pushing briefly on the same button will wake up the system within seconds.
NOTE:
Avoid using the Power Button (“hold 4+ seconds” feature) to turn off the device—this form of
hardware shutdown is intended to be a means of recovery from device lockups, and not as normal
operation.

Start Up
If the power up (from Standby or otherwise) is successful, the appropriate interface will be displayed after a
launch sequence of several seconds.
Configuring the Mobile Tablet
The device may be configured using the utilities and methods dictated by the software operating system. The
DT398 should be configurable for various properties such as user profiles, network features, and several system
elements.
Calibration
The touch display for the DT398 is calibrated before shipping. In the event that the calibration has been modified
or is unsatisfactory, the respective calibration routines (e.g., PenMount (PM) to calibrate the touch interface may
be used. Such applications are typically executed through touch input via Stylus or through mouse click via a
USB mouse.
Brightness Control
To control the screen brightness, launch the System Utility. The System screen will display a Brightness control
section with up and down arrows that can be activated with the stylus.
Battery and Power Management
The DT398 is equipped with an internal 1880mAh Li-Ion battery pack that is capable of supporting approximately
3 - 4 hours of continuous operation. With the internal battery and an external battery pack that clips
(hot-pluggable) onto the back of the device, the maximum period of continuous operation will be approximately 6
- 8 hours. The period between battery recharges can be significantly lengthened by putting the device into
Standby mode through the Power Button (see Buttons Function Table) whenever the device is not in use.
Depending on the operating software, the DT398 may also be configured to enter various power-saving modes
via the Power Button or through timed entry.

USING THE Mobile Tablet
Peripherals Support
Through its USB port, the DT398 supports a wide range of USB-based peripherals. These peripherals are
applicable for software installation, applications storage, data storage, docking or software recovery and update.
The DT398 is complemented by an optional Desktop Cradle or Wall/ Vehicle Mount Cradle for support,
pass-through charging, and connection to a range of USB peripherals, including keyboard and mouse. The
Cradles offer the following interfaces: a DC-in port for the AC-DC adapter, an Ethernet port, a VGA output and
USB ports. Always seat the DT398 securely onto the cradle. The cradle must be powered by the AC-DC adapter
for the Ethernet and USB ports to function. The battery packs on the DT398 may be recharged by connecting the
AC-DC adapter directly to the DC-in port on the DT398 or through the DC-in port on the Cradle while the DT398
is docked.
For More Support
Users can download the Software Utility and Modules Operation Guides from the DT Research website.
If the DT398 comes with a 3G module, please contact your product and/or service provider for the SIM Card Slot
Location and Insertion Guide.
