16-1 Data Communication Overview

This section provides an overview of the types of connections that are possible, and the data that can be transferred over each connection. It also tells you how to use the Communication application to transfer data.

Important!

•Never press the P button on the back of the ClassPad while a data communication operation is in progress. Doing so can damage memory, resulting in loss of all memory contents and malfunction of your ClassPad. If this happens, you will need to request repair from your CASIO Maintenance Service Provider. Note that repair of your ClassPad will not recover any lost memory contents.
