PRECAUTIONS

• Always exercise care when operating and handling the LT320.
• Do NOT apply excessive pressure to the display screen.
• We recommend using the Digital Pen (optional) to keep the screen clean.
• Avoid prolonged exposure of the display panel to any strong heat source. Wherever possible, the LT320 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 off the LT320 and disconnect all power sources. Report the problem to your device provider immediately.
• Never attempt to disassemble the LT320, as this will void the warranty.

NOTE:
To obtain protection consistent with any IP rating for the device, the I/O (audio, power, USB, card reader, etc.) port doors must be closed. If the IP protection is compromised by mishandling or misuse, such as by leaving port doors open or improperly closed, any resulting product damage will not be covered under any DT Research warranty.

BASIC FEATURES

The LT320 rugged laptop integrates a high‐brightness touchscreen, USB ports, and embedded networking elements such as wireless LAN and Bluetooth or optional 4G LTE/ AWS.

A LT320 typically integrates an 802.11ac wireless LAN (WLAN) adapter that may connect to other wireless devices or access points. If your LT320 does not come with such a network adapter, please consult your device provider to establish the desired network connectivity.

OPERATION

Powering ON and OFF

To activate the LT320, push and quickly release the Power Button. The display will come on in a few seconds. To put the LT320 in Standby mode, push and quickly release the Power Button. To turn the LT320 off for extended storage, power off safely using any software function that “shuts down computer” provided in the software operating system.

NOTE:
The battery pack shipped with your laptop may be low in power—please use the AC‐DC adapter with the LT320 when setting up for the first time to fully charge the battery pack, or use the optional battery charger kit.

NOTE:
When the battery pack is charging, the blue 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 LT320 a few times to activate the charging process.

NOTE:
To conserve power, use (push and quick release) the Power Button to put the laptop 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 laptop— 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 mode 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 Rugged Laptop
The LT320 may be configured using the utilities and methods dictated by the software operating system. The LT320 should be configurable for various properties such as user profiles, network features, and several system elements.

Covert the LT320

1. Unlock the latch to release the keyboard from the screen

2. Gently pull out the keyboard

3. Rotate the keyboard against the back of the screen

NVIS Mode and Screen Brightness Control (optional)

• When power button is pressed to power on the unit, power LED will flash orange once to indicate the unit is booting. 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” buttons 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” button. 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 buttons 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 buttons to change display to desired brightness.
• Brightness up, Brightness down, NVIS/Normal toggle, Windows Key and Control Center functions are fixed and not user programmable.
• Two programmable buttons on left side can be programmed through Button Manager.

Wireless Networking

Wireless LAN

The LT320 is often delivered with an embedded (user‐inaccessible) 802.11ac WLAN adapter equipped with a hidden custom antenna.

• Through the support of typical WLAN adapters, the LT320 should be able to detect all 802.11 access points in the vicinity to select the access point of choice for connection.
• The SSID and WEP/WPA/WPA2 (if enabled) parameters on the LT320 and the access points have to match. The SSID is case‐sensitive and it is recommended to enable WEP/WPA/WPA2 encryption (or advanced alternatives) for secure access.
• When WEP/WPA/WPA2 is enabled, you may need to consult your network administrator or your networking equipment literature to properly configure associated settings such as Authentication mode, etc.
• Refer to the access point operating manuals for setting up the 802.11 access points.

Bluetooth

The Bluetooth configuration application is enabled from the System Tray or from the Windows Mobility Center. Follow the instructions and options provided within the application to configure and invoke Bluetooth connectivity with the corresponding peripherals.
