The Dictionary Synchronizer lets you synchronize the custom
dictionary used in Microsoft Word with the custom dictionary
used in Pocket Word on the handheld PC. Sharing a custom
dictionary is useful when performing spell checking in either
application.
To synchronize dictionary terms, follow these steps:
1. Be sure the Dictionary Synchronizer is installed on your
computer. For more on this, see "Step 5: Installing the
Compaq C-Series Software" in Chapter 2.
2. Connect the auto-sync cable or establish an IR link between
the computer and handheld PC.
3. On the computer, select Start Programs Compaq
C-Series Dictionary Synchronizer.
4. In the screen that appears, tap Synchronize.
5. A status indicator appears while the synchronization occurs.
6. When synchronization is complete, select the OK button to
close the application.
Your custom dictionaries are now synchronized. You can update
the dictionaries at any time by repeating this process.
