i when setting up the device for the first
time to fully charge the internal battery pack. You may charge the external battery

NOTE:
When the battery pack(s) is (are) charging, the blue-colored Battery LED

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.

The device may be configured using the utilities and methods dictated by the
software operating system. The DT39

i should be configurable for various
properties such as user profiles, network features, and several system elements.
Calibration
The touch display for the DT39

i 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.
Wireless Networking
Wireless LAN
The DT39
