Testing a touch panel for continuity

The keypad works by making a connection between 2 of the 8 pins on the connector. The Canalyzer CPU detects these connections and interprets it as a certain key press. To test the operation of your keypad, place the leads of a meter set to test continuity on the appropriate pins and press the key you wish to test. You should see an indication on the meter of a change in continuity if the key is working properly.
