The keypad may be faulty or a button may be stuck.

Follow these steps to identify the problem:

  1. Run the keypad diagnostics by holding down Time +/- and Level +/- at the same time.
  2. When D3 (Keypad test) is displayed, press Enter to start the test. (On older black models the test begins automatically.)
  3. Press each button on the keypad and you should hear a beep. If a button does not beep, the key may be stuck or the membrane could have been damaged and will need to be replaced.
  4. To exit the Keypad test, press Pause Clear two times.
