Tone Test
When you press 1 on the DTMF keypad, the speaker sounds a Ringer Tone. If you pick up the handset, the ringing stops and a Busy tone is sent to the handset.
The LCD shows the following display:

LCD Test
When you press the 2 on the DTMF keypad, the LCD displays a pattern of dark characters. Missing dots, if any, will be evident.
When you press the 3 on the DTMF keypad, the LCD displays the first set of display characters supported by the set. Press 3 again to display the rest of the supported display characters.
To exit from either test, press any multifunction key, softkey, or DTMF key.
Memory Tests
Pressing 4 on the numeric keypad starts an automatic sequence of tests, performing memory and line tests in order.
The first of these tests writes to and reads from all RAM locations. If any error is detected, the test sequence stops at that point and reports by displaying an error code on the display; for example:
SELF TEST EXECUTING (MEMORY/LINE TEST)
