stand, as shown in Figure 4. Hold the electrical base in place and set the stand in its normal upright position on a flat
surface, being careful not to let the electrical base shift as you do so.
Lift the stand from the electrical base by grasping the arm and lifting straight up until the bottom of the stand well clears
the electrical base. If the unit contains a light preset control and switch, be sure to disengage the printed circuit board
containing the preset control and switch from the notch in the side of the base before lifting the stand clear of the
electrical base.
The stand, without the electrical base, may now be placed on a clean flat surface in its normal upright position. With the
electrical base removed, the fragile illumination components are exposed on the open bottom of the stand and may be
damaged if the stand is not placed on a suitable clutter‐free surface. Store the stand someplace out of harm's way and
where dust and debris will not accumulate on the exposed lighting components.

Setting Up for Troubleshooting the Base
Set the electrical base on a suitable work surface. If the unit includes a light preset control/switch, orient the printed
circuit board containing the control and switch such that it will not make contact with the chassis or any other
electrically conductive items during the troubleshooting process.
Carefully plug the lamp house into J103 on the rear of the electrical base, as shown in Figure 5, making sure both contact
pins of the lamp house engage the mating receptacles of J103. The lamp house will be fragile and unsupported when
plugged into the electrical base without the stand, since the two alignment/support pins on the lamp house will not be
engaged with the mating holes in the stand. Once again, do not touch the halogen lamp with your fingers.
