Battery Charge Level States
The charge level state of the battery is also listed in the
Power Properties / Battery
tab window. There are
three charge level states. When the battery gauge is “Very Low”, the battery should be immediately
charged by connecting the unit to an AC adapter or the unit will automatically shut down when the
voltage level drops below the minimum threshold.
•

Battery charge is Good
•
Low:
Battery charge is Low (<10% remaining)
•

Battery charge is Very Low / Critical (4% remaining)

Other Indicators
There are three user warnings that occur when the battery level is “Very Low”: See sections 4.2 and 4.3
for the LED and tone indicator states that also provide user feedback regarding battery charge levels and
charging states.
•
The power LED alternately flashes Red and Green (see section 4.3)
•
A warning message pops up “
Main Battery Very Low
”. This warning will repeat itself
periodically until the condition clears or the unit automatically shuts down.

An error beep sounds when the battery charge level is critical.

Creating Desktop Shortcuts
To create desktop shortcuts, locate the application for which you want to create a shortcut. Tap and hold
the stylus on the application until the options menu pops up. Select
Copy
and go to the directory where
you want to put the shortcut. Tap and hold the stylus until the options menu pops up and select “
Paste
Shortcut
”.
5.6
Safe Boot Mode
The system provides a mechanism that permits the recovery of lost or damaged
operating system files via a “Safe Boot” mode. This mechanism is similar to
Microsoft Windows Safe Mode that is available on PCs. If one or more
operating system files have been damaged or inadvertently deleted, when the
unit is turned on it will automatically boot-up into a smaller, limited function
version of Windows CE that will permit the recovery of the files or allow them
to be replaced or overwritten. This permits the unit to be repaired, and then
subsequently rebooted using the full version of Windows CE. Safe Boot mode
can also be accessed on demand by holding down the
F1
key while turning on
the power to the unit. A special bitmap will appear indicating that the unit is
booting-up in Safe Boot mode.

Software Utilities
All of the utilities listed below except “
DsVerify2About
” are located in the
My Device\Hard Disk\DSV3
directory. The “
DsVerify2About
” is a hidden file in the
\My Device\Windows
directory. There are
additional demonstration programs available as source code for custom software development in the
Datastrip MT SDK (sold separately).
