3. Where do I download this PocketPC2002 update?

If you have a Compaq IPAQ

1. On your desktop PC, go to this URL to get the EUU2 update: http://www.compaq.com/support/files/handhelds/us/download/15068.html

Click on "download" to download the EUU file from HP/COMPAQ. When the file is downloaded on your desktop PC, open it. Go through with the installation and when it is done, the update files will be stored in a directory on your desktop PC.

2. Now on your PC, open Windows Explorer and go to C:\IPAQ\SP21191 - this is where the update is - keep this window open.

3. Put your IPAQ in its cradle and connect it to the PC via Activesync.

4. In Activesync, click on "Explore" to see files on your IPAQ.

5. Copy the file "PPCEUU2_ENG.CAB" from the first window (in c:\IPAQ\SP21191) to the IPAQ window.

6. Make sure your IPAQ is in its cradle and IT IS CHARGING.

7. Now with your stylus (and while your IPAQ is still in the cradle) go to START\PROGRAMS and open File Explorer. Make sure you can see the PPCEUU2_ENG file (it will be in "My Documents" folder).

8. Tap on the PPCEUU2_ENG file. This starts the update! Wait until the update is done (it will take around 5 minutes). During this time, don't touch the IPAQ.

That's it! Now run Contax, Essential Contax or Essential Contax PRO.

Note: The directory and the file referred to above are valid for the US version of the PocketPC2002 update. For other language versions (German, French, Spanish, etc), go to “C:\IPAQ\” and find your country code
