Four Flashing Lights

If all four lights are flashing on a JF-2MED, there is a short on one of the A1/A2 wires that connect it to the door station. It is best to bench test the door station with the JF-2MED to see if the issue goes away on a different wiring connection.

Two Solid Lights

If two lights are constantly lit on the front of the JF-2MED, that means that the clock has not been set. See these instructions to correct the issue; see pages 7 and 8 of the full instructions linked above.
