KEYPAD BUTTONS ARE NOT RESPONDING

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

Follow these steps to identify the problem:

  • Run the keypad diagnostics by holding down Time +/- and Level +/- at the same time.
  • When D3 (Keypad test) is displayed, press Enter to start the test. (On older black models the test begins automatically.)
  • 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.
  • To exit the Keypad test, press Pause Clear two times.
