The indirect panel is identical to the above 6-metre chart except letters printed in reverse (indirect) for viewing via a mirror. This indirect version is only available in the 6-metre configuration. Made from 2mm Opal white acrylic plastic sheet. Letters: Black, non-reflective Contains the single 6/6 line This chart is available for reading at 4 and 6 metres from the patient Panel Size: 530mm x 230mm (All panels are the same size) Because there are many sizes of illuminated wall mounted cabinets and boxes, the panels are larger so they can be cut to size. This should be done with an electric saw. To avoid edge cracking and chipping, masking tape should be fixed through the cutting line on both sides of the panel. Alternatively, most plastic sign makers will be able to cut the material cleanly and accurately to size. Ensure the letters are covered with soft paper or plastic to avoid scratching the printed letters. Product reference: EYTTL4DX 4 metre chart EYTTL6DX 6 metre chart EYTTL6DXI – 6 metre Indirect chart
