Error Message Table
k Low Memory Error Processing
An error occurs on the ClassPad if it is unable to reserve enough work area memory to
perform a particular operation. When a low memory error occurs, any application in use at
that point is shut down and an error message like the one shown below appears.
Tapping the [OK] button clears the error.
Important!
• To avoid loss of data, you should make it a regular habit to periodically perform the save
operation.
You may lose some of the data you are inputting with an application that shuts down due to a
low memory error. When the low memory error occurs while you are using the eActivity
application to create data, for example, any unsaved data you have input is lost.
Batteries are extremely low!
Replace batteries immediately!
