Button Management
Where supported by software, many of the hard buttons on the WebDT 390 are
programmable to perform a function of the user’s choice. The exception is the Power
Button and the SAS Button. To activate the button re-assignment application, invoke the
Button Manager application, e.g., in Windows XP Embedded.
Brightness Control
Where supported by device firmware and software, a hard button may be engaged to
manipulate the display brightness. Press the System Menu button (Button 7) on the front
of the WebDT 390. The System screen will display a Brightness control section with up
and down arrows that can be activated with the stylus.
Battery and Power Management
The WebDT 390 is equipped with an internal 3760mAh Li-Ion battery pack that is
capable of supporting approximately 3 - 4 hours of continuous operation. With the
internal battery and an external battery pack that clips (hot-pluggable) onto the back
of the device, the maximum period of continuous operation will be approximately 6 - 8
hours. The period between battery recharges can be significantly lengthened by putting
the device into Standby mode through the Power Button (see Buttons Function Table)
whenever the device is not in use. Depending on the operating software, the WebDT 390
may also be configured to enter various power-saving modes via the Power Button or
through timed entry.
Desktop Cradle
The WebDT 390 is complemented by an optional Desktop Cradle for support, pass-
through charging, and connection to a range of USB peripherals, including keyboard and
mouse. The Cradle offers the following interfaces: a DC-in port for the AC-DC adapter,
an Ethernet port, and USB ports. Always seat the WebDT 390 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 WebDT 390 may be recharged by connecting the
AC-DC adapter directly to the DC-in port on the WebDT 390 or through the DC-in port on
the Desktop Cradle while the WebDT 390 is docked to the Cradle.
