Introduction
Maintenance mode allows you to display technical information about the InTouch
DX, perform configuration tasks, and execute diagnostic tests. These tests can
help you troubleshoot hardware malfunctions.
Important: The application software for the device resides on the SD (Secure
Digital) card, which is in the unit. Copying or altering the SD card voids your
warranty.
