Display messages If an error occurs, the MAC Aura XB gives fixture status readouts in the display. See Display messages on page 32. Lubrication In general, the MAC Aura XB does not require lubrication. However, depending on use conditions, the moving parts in the pan and tilt mechanisms may eventually require reapplication of lubricant. Excessive noise during pan/tilt movement is a sign that lubrication maybe required. This operation can be carried out by a Martin service partner if necessary.
