Self-Test Procedure

NOTE: 9600 Series IP Telephones store two software code images in reprogrammable non-volatile memory. The primary image, called the “big app” must be running to perform a self-test. The backup image, called the “little app” does not support the self-test.

2. To terminate the self-test, press the # button on the dial pad at any time. Doing so generates a confirmation tone, and returns the user interface to its previous state.
