Reference Drawings:
Shop Drawings .......................................................... Refer to Appendix A
The internal components of the KE-1010 displays may be reached once the face
panel is removed. Never attempt to lift the entire display or carry the face panel
using the suction cups.
To remove the face panel:
1. Disconnect power to the display.
2. Using the suction cups, provided with the display, slide the face panel up
toward the top of the display (refer to the Shop Drawings).
3. Pivot the bottom edge of the panel out of the support groove. The face
panel should now be free of the display cabinet.
4. Carefully remove the face panel. The LED modules will now be accessible.
5. Remove the appropriate module (refer to Section 4.2) to access the internal
electronic components.
To replace the face panel:
1. Using the suction cups to hold the face panel, slide the face panel into the
groove in the top of the cabinet.
2. Pivot the face panel into the cabinet, and then lower it down into the groove
in the bottom of the cabinet (refer to Face Panel Removal Detail in the
Shop Drawings). Note: The face panel may be slightly wavy and may not
slide neatly down into the groove. If the face panel does not easily slide,
then starting at one end of the display, gently press your hand against the
bottom edge of face panel to slide it into the bottom support groove.
3. Once the face panel is secure, remove the suction cups from the face panel.
