Exiting the Program

Caution: Some of the commands available to you from this menu are designed for advanced

debugging and system testing only, and can cause the module to stop communicating with the

processor or with other devices, resulting in potential data loss or other failures. Only use these

commands if you are specifically directed to do so by ProSoft Technology Technical Support staff.

Some of these command keys are not listed on the menu, but are active nevertheless. Please be

careful when pressing keys so that you do not accidentally execute an unwanted command.
