and on, the user is encouraged to try to correct the interference by one of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separaon between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that to
which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
FCC Cauon: Any changes or modicaons not expressly approved by the
party responsible for compliance could void the user’s authority to operate
this equipment.
This device complies with Part 15 of the FCC Rules.
Operaon is subject to the following two condions: (1) This device may not
cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operaon.
This device and its antenna(s) must not be co-located or operang in
conjuncon with any other antenna or transmier.

PRECAUTIONS
• Always exercise care when operang and handling the LT355.
• Do NOT apply excessive pressure to the touch screen (oponal).
• Avoid prolonged exposure of the display panel to any strong heat source.
Wherever possible, the LT355 should face away from direct light to reduce glare.
• If the AC-DC power adapter is used to recharge or power the laptop, do NOT
use any AC-DC adapter other than the one provided or acquired from the
manufacturer or its partners.
• In the unlikely event that smoke, abnormal noise, or strange odor is present,
immediately power o the LT355 and disconnect all power sources. Report the
problem to your device provider immediately.
• Never aempt to disassemble the LT355, as this will void the warranty.
BASIC FEATURES
The LT355 rugged laptop integrates a high-brightness screen, USB ports, and
embedded networking elements such as wireless LAN and Bluetooth.
A LT355 typically integrates an 802.11 wireless LAN (WLAN) adapter that may
connect to other wireless devices or access points. If your LT355 does not come with
such a network adapter, please consult your device provider to establish the desired
network connecvity.
NOTE:
To obtain protecon consistent with any IP rang for the device, the I/O (audio,
power, USB, card reader, etc.) port doors must be closed. If the IP protecon is
compromised by mishandling or misuse, such as by leaving port doors open or
improperly closed, any resulng product damage will not be covered under any
DT Research warranty.

Start Up
If the power up (from Standby mode or otherwise) is successful, the appropriate
interface will be displayed aer a launch sequence of several seconds. The wireless
LAN connecon may take 10-15 seconds to be established.
Configuring the Rugged Laptop
The LT355 may be congured using the ulies and methods dictated by the
soware operang system. The LT355 should be congurable for various properes
such as user proles, network features, and several system elements.

OPERATION
Powering ON and OFF
To acvate the LT355, push and quickly release the Power Buon. The display will come
on in a few seconds. To put the LT355 in Standby mode, push and quickly release the
Power Buon. To turn the LT355 o for extended storage, power o safely using any
soware funcon that “shuts down computer” provided in the soware operang
system.
NOTE:
The baery pack shipped with your laptop may be low in power—please use the
AC-DC adapter with the LT355 when seng up for the rst me to fully charge
the baery pack, or use the oponal baery charger kit.
NOTE:
When the baery pack is charging, the blue Baery LED should blink slowly.
If plugging in the AC-DC adapter does not trigger this blinking acvity and the
LED stays dark, the baery pack(s) may have been drained substanally. Try
unplugging/ replugging the AC-DC adapter to the LT355 a few mes to acvate
the charging process.
NOTE:
To conserve power, use (push and quick release) the Power Buon to put the
laptop in “Standby” mode while not in use. Pushing briey on the same buon
will wake up the system within seconds.
NOTE:
Avoid using the Power Buon (“hold 4+ seconds” feature) to turn o the
laptop—this form of hardware shutdown is intended to be a means of recovery
from lockups, and not as normal operaon.

NVIS Mode and Screen Brightness Control (optional)
• When power buon is pressed to power on the unit, power LED will ash orange
once to indicate the unit is boong. Unit will boot into NVIS mode with zero nit
brightness by default and display will be dark. You can press the “Brightness Up”
and “Brightness Down” buons to set NVIS mode display to desired brightness
(up to 20 nits).
• To toggle between NVIS and high-brightness display mode, press the “NVIS/
Normal Mode Toggle” buon. When changed from NVIS mode to high-brightness
mode, display brightness percentage will be same as the brightness level set in
NVIS mode before toggling.
• Use brightness control buons to set desired brightness level. When changed
from normal display mode to NVIS mode, display brightness will be set to 0 nit
(display is dark) and you need to use brightness control buons to change display
to desired brightness.
• Brightness up, Brightness down, NVIS/Normal toggle, Windows Key and Control
Center funcons are xed and not user programmable.
• Two programmable buons can be programmed through Buon Manager.

USING THE RUGGED LAPTOP
Peripherals Support
Through its USB 3.0 ports, the LT355 supports a wide range of USB-based
peripherals. These peripherals are applicable for soware installaon, applicaons
storage, data storage, and system soware recovery and updates.
For More Support
Users can download the Laptop Modules Basic Operaon Guides from the DT Research
website.
If the LT355 comes with a Mobile broadband module, please contact your product
and/or service provider for the SIM Card installaon procedures.

Wireless Networking
Wireless LAN
The LT355 is oen delivered with an embedded (user-inaccessible) 802.11 WLAN
adapter equipped with a hidden custom antenna.
• Through the support of typical WLAN adapters, the LT355 should be able to
detect all 802.11 access points in the vicinity to select the access point of choice
for connecon.
• The SSID and WEP/WPA/WPA2 (if enabled) parameters on the LT355 and the
access points have to match. The SSID is case-sensive and it is recommended to
enable WEP/WPA/WPA2 encrypon (or advanced alternaves) for secure access.
• When WEP/WPA/WPA2 is enabled, you may need to consult your network
administrator or your networking equipment literature to properly congure
associated sengs such as Authencaon mode, etc.
• Refer to the access point operang manuals for seng up the 802.11 access
points.
Bluetooth
The Bluetooth conguraon applicaon is enabled from the System Tray or from the
Windows Mobility Center. Follow the instrucons and opons provided within the
applicaon to congure and invoke Bluetooth connecvity with the corresponding
peripherals.
