The LEDs are not lighting up
1. Check that the buzzer on the QX100 beeps when you turn on the
reader.
• If NO, act according to "The reader appears to have no
power".
• If YES, hold a PICC card up to the landing zone on the reader.
If some of the LEDs light up, the ones that do not are burnt
out. To change a LED, contact a VeriFone certified
representative.
2. If the problem persists, contact a VeriFone certified service
representative.
