Step 1: Remove Front Panel
1.1 Disconnect unit from power supply.
1.2 Remove 2 (two) Phillips head screws that attach front panel to cabinet. The screws are located on the lower
left and right sides of the front panel as noted in the following images.
While rare, excessive vibration during shipment may cause the ribbon cable that connects the front control
panel to the control board to become disconnected. This can result in a unit that will not power on and/or may
appear to power on but will not perform all functions correctly. To remedy this issue, the ribbon cable
connection must be checked and re-connected if loose or disconnected.
