Your Pocket LOOX...
... is equipped with the Office applications MS-Word, Excel and Outlook. In Outlook you can not only
receive and send e-mails, you can also manage your appointments and let me remind your of the
things you have to do. You can access names, e-mail addresses and telephone numbers while you
are away from your home or office. You can store notes in written form or verbally as with a dictation
device. Memory cards ensure that even large amounts of data can be carried along reliably.
In the office you can then effortlessly transfer all your data and newly created documents to your
notebook or PC. Install ActiveSync on your notebook or PC, connect the Pocket LOOX to your
notebook or PC and you can synchronise your data.
Why don't you read your favourite book quite comfortably on the display or use the MP3 player while
you're on the road. Insert the memory card of your digital camera in the slot and you can view the
photos you just took on the display.
With Bluetooth, the infrared interface and the integrated Wireless LAN (depending on the model),
you can also connect to other devices in your office and on the go without bothersome cables. For
example, thanks to Bluetooth you can access the Internet without any cables with your Bluetoothcapable mobile phone. With the Pocket Internet Explorer you can visit both web and WAP pages.
The following documentation contains additional information on your Pocket PC and the Windows
Mobile operating system:
• in the manuals "Safety and Ergonomics" and ”W arranty"
• in the "Getting Started" manual
• in the help on your Pocket PC.

This chapter contains information on the proper, safe use of your Pocket PC. Please be sure to
observe the following safety precautions to prevent damage to your device, data loss or damage to
your health. The information on saving energy, charging the battery and cleaning your Pocket PC
are very important for proper operation of the Pocket PC. To protect the environment, we urgently
ask that you observe the disposal and recycling information.
Keep this operating manual together with the device. If you pass on the device to a third party,
please also pass on the operating manual.
Safety notes
Pay attention to the information provided in the "Safety and Ergonomics" manual and in
the following safety notes.
!
• Your Pocket PC is a technical device that contains small parts. Therefore, please keep your
Pocket PC out of reach of children under 36 months of age.
• During installation and before operating the device, observe the instructions on environmental
conditions in the "Operating the Pocket PC" and "Technical data" chapter.
• Connect the power adapter plug to the PSC11R-050 power adapter. The power adapter plug
must never be plugged into an electrical outlet without the PSC11R-050 power adapter.
• The included PSC11R-050 power adapter complies with the requirements of the country in
which you purchased the Pocket PC. Make sure the PSC11R-050 power adapter is approved
for the country in which it is used.
• The PSC11R-050 power adapter may only be connected to an electrical outlet when the
Pocket PC or the cradle is connected to the PSC11R-050 power adapter.
• Do not use the PSC11R-050 power adapter for other devices.
• Do not use power adapters which are not specially approved for this Pocket PC.
• You may only operate the Pocket PC with the PSC11R-050 power adapter if the nominal
voltage of the PSC11R-050 power adapter (100 V to 240 V) matches the local mains voltage.
• During transport and on trips, observe the safety precautions in the sections "Transporting
Pocket PC" and "Information on travelling".
This Pocket PC complies with the relevant safety regulations for data processing equipment. If you
have questions as to whether you can set up the optional cradle and the Pocket PC in the intended
environment, please contact your sales point or our hotline/help desk.

Information before you start
Energy saving
Switch off your Pocket PC with the Suspend/Resume button when you don't need it. In the system
settings you can specify after how many minutes the Pocket PC switches off when it is not used
(see the "Configuring the Pocket PC" chapter).
While you are working, and if the ambient light conditions permit, you can reduce the display
brightness or even switch off the display lighting completely. The Pocket PC is equipped with a
transflective display that reflects incident light and enables you to work even under unfavourable
lighting conditions.
Switching off and on of the display lighting can also be specified in the system settings of your
Pocket PC (see the chapter "Configuring the Pocket PC").
If you use the energy saving functions, you can work with the Pocket PC longer before having to
recharge the battery. We particularly recommend that you reduce the display brightness to
effectively save energy and therefore appreciably increase the time you can work with the battery.
Disposal and recycling
Do not throw batteries or accumulators into the household waste.
Our devices are mostly produced of materials that can be turned over for proper recycling. The
device may be taken back after use to be recycled, provided that it is returned in a condition that is
the result of normal use. Any components not reclaimed will be disposed of in an environmentally
acceptable manner. To give back a device please take advantage of your country's disposal and
recycling possibilities.
Further information about country-specific disposal and recycling possibilities can be found on the
following website www.fujitsu-siemens.com/recycling.
If you have any questions on disposal, please contact your local office or our Help Desk.

• Do not connect your Pocket PC to your computer (PC/notebook) yet. Before the first
data synchronisation between your Pocket PC and your PC/notebook, you must
install the program ActiveSync on your PC/notebook.
Installing ActiveSync on your PC/notebook
The data synchronisation helps you always keep your data on your Pocket PC and your
PC/notebook up to date when you work alternately with your PC/notebook and your Pocket PC. You
can transfer data you require when you're on the go from your PC/notebook to the Pocket PC using
the data synchronisation feature. In the same way, you can copy the latest results of your work from
the Pocket PC to your PC/notebook.
The ActiveSync cable and the ActiveSync software are provided for data synchronisation. ActiveSync
is already installed on your Pocket PC. You need only install ActiveSync on your PC or notebook.
The ActiveSync program and the required drivers are contained on the Microsoft Companion CD.
► Insert the Microsoft Companion CD in the optical drive of your PC/notebook.
The installation program of ActiveSync will start.
16 A26391-K150-Z120-2-7619
Operating the Pocket PC
If the installation program of ActiveSync does not start automatically, you must double-click on the file
Setup.exe of ActiveSync.
► Click on Start here and follow the instructions on the screen.
► Prepare the Pocket PC as described in the section "Starting Pocket PC the first time".
During the installation the software attempts to establish a connection to the Pocket PC.
If you have not yet installed Outlook 2002 on your PC/notebook, you must install it on your
PC/notebook before the first data synchronisation between your Pocket PC and your
i
PC/notebook. Outlook 2002 is provided on the included Microsoft Companion CD.

► Connect the ActiveSync cable to a USB port (1) of your PC/notebook.
The Pocket PC is now connected to your PC/notebook. The ActiveSync partnership between your
Pocket PC and your PC/notebook will be established. The ActiveSync Setup Wizard will help you do
this.
First data synchronisation between the Pocket PC and the PC/notebook
After you have specified the desired and required settings for the synchronisation in the Wizard, the
first synchronisation starts automatically.
ActiveSync is now installed on your PC/notebook and your Outlook data are synchronized with your
new Pocket PC.
