Hi...i am a new user here. As per my knowledge you should open both doors by checking the checkboxes. Wait for machine to boot and press cancel when it asks to read meters. Then press the test button at the top of MFME.Scroll through to lamp test using transfer button and press start to accept.Then it will flash all lamps, press cancel, then use transfer to scroll through all the lamps and the alpha will tell you what lamp is lit
