THE WebDT 390
OPERATION
Internal Battery Switch
To prevent battery drain during shipping and extended storage, the internal battery
may be turned off. To turn on the internal battery, unscrew the 6 screws and open the
battery cover (Picture 1). Push the battery button switch to the "up" position (Picture
2). The internal battery pack has to be turned on for it to operate, be charged, and for
the optional external battery pack to function.

Powering ON and OFF
To activate the WebDT 390, push and quickly release the Power Button to the right
side of the front bezel. The display will come on in a few seconds. To put the WebDT
390 in Standby mode, push and quickly release the Power Button. To turn the WebDT
390 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 WebDT 390 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 WebDT 390, 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 WebDT 390 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. The wireless LAN connection may
take 10-15 seconds to be established.
Configuring the WebDT 390
The device may be configured using the utilities and methods dictated by the
software operating system. The WebDT 390 should be configurable for various
properties such as user profiles, network features, and several system elements.
Calibration
The touch display for the WebDT 390 is calibrated before shipping. In the event
that the calibration has been modified or is unsatisfactory, the respective calibration
routines (e.g., PenMount (PM) for Windows XP) 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.
