4. When installing glass gobos the circular indentation in the retaining ring is used to accommodate the greater thickness of the glass gobo and therefore should be facing inwards Note These notes are intended to help the user however no responsibility will be accepted for any actions arising from there implementation a Due to the heat generated in the fixture new metal gobos tend to warp when they are first used in a fixture Although this is normal it can potentially cause problems when two gobos are counter rotating closely together It is suggested that new gobos are pre heated in the fixture before actual use of the unit The gobo warpage can then be observed and corrected if necessary If the units are used for different shows in repertory it may be worth marking a line on the gobo and holder to show the zero position alignment of the gobo If a gobo is made of very thin material it may spin freely in the holder and therefore loose registration A small spot of high temperature silicon rubber between the gobo and the retaining ring should hold it in place When using etched glass gobos the uncoated side of the gobo should always be nearest to the fixture light source 3 3 Operating the unit All the unit functions are accessed using the LED display and the three push button switches on the rear panel Display Red Black Brown Button Button Button OC Version 1 0 May 2003 DHA IRTR203 Mk2
