• Always exercise care when operating and handling the Tablet.
• 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 Tablet should face away from direct light to reduce glare.
• If the AC-DC power adapter is used to recharge or power the tablet, do NOT use any
AC-DC adapter other than the one provided with the tablet 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 Tablet and disconnect all power sources. Report the
problem to your device provider immediately.
• Never attempt to disassemble the Tablet, as this will void the warranty.
Basic Features
The Tablet wireless tablet integrates a bright and responsive touch display, 1 USB
port, and embedded networking elements such as Wi-Fi or optional 3G. The Tablet is
complemented by a suite of accessories, including battery expansion, docking cradles,
and wall/ vehicle mount cradles, for a comprehensive user experience.
A Tablet typically integrates an 802.11 Wi-Fi adapter that may connect to other wireless
devices or access points. If your Tablet does not come with such a network adapter,
please consult your device provider to establish the desired network connectivity.
Powering ON and OFF
To activate the Tablet, push and quickly release the Power Button. The display will come
on in a few seconds. To put the Tablet in Standby mode, push and quickly release the
Power Button. To turn the Tablet off for extended storage, power off safely using any
software function that “shuts down computer” provided in the software operating
NOTE: The battery packs shipped with your tablet may be low in power—please use
the AC-DC adapter with the Tablet when setting up for the first time to fully charge the
internal battery pack. You may charge the external battery pack with it attached to the
Tablet, 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 Tablet a few times to activate the charging process.
NOTE: To conserve power, use (push and quick release) the Power Button to put 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 tablet—
this form of hardware shutdown is intended to be a means of recovery from 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. The wireless LAN connection
may take 10-15 seconds to be established.
Configuring the DT398B/ DT398H/ DT398B-MD/ DT398B-MD-C
The tablet may be configured using the utilities and methods dictated by the software
operating system. The Tablet should be configurable for various properties such as user
profiles, network features, and several system elements.
DT398B/ DT398H/ DT398B-MD/ DT398B-MD-C
The touch display for the Tablet 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.
Wireless Networking
The Tablet is often delivered with an embedded (user-inaccessible) 802.11a/b/g/n Wi-Fi
adapter equipped with a hidden custom antenna.
• Through the support of typical Wi-Fi adapters, the Tablet should be able to detect all
802.11 access points in the vicinity for you to select the access point of your choice
for connection.
• The SSID and WEP/WPA/WPA2 (if enabled) parameters on the Tablet and the access
points have to match. The SSID is case-sensitive and it is recommended that you
enable WEP/WPA/WPA2 encryption (or advanced alternatives) for secure access.

Peripherals Support
Through its USB port, the Tablet 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 Tablet 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, video outputs and USB ports. Always seat the
Tablet 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 Tablet may be recharged
by connecting the AC-DC adapter directly to the DC-in port on the Tablet or through the
DC-in port on the Cradle while the Tablet is docked.
Remote Management
Depending on software configuration, the Tablet can be centrally managed for asset
