activate if presets are ON.

Example shown: Preset 1 active; presets 2-8 have scenes stored but inactive.

RECORDING THE SCENES (PRESETS)
SceneSwitch has 8 static memory buttons (presets, 1-8). These static scenes contain asnapshot of all DMX channel values in all 8 possible input universes at the time they werecaptured.
To record one of the 8 static memories, choose from which DMX input the memories will berecorded (A or B DMX input) and switch the input selector to the chosen input (A or B position).
Once this is done, follow this sequence:1)

Use the lighting console to set the necessary DMX channel levels (create the desired lighting
preset to be recorded on SceneSwitch preset button).
2) Perform a visual check making sure the preset is as you want it to be (necessary beam angle,brightness and color levels).
3) Press and hold the chosen memory button for 5 seconds or longer.
4) When LED status indicators start to blink, release the memory button.
5) When the memory is recorded the LED status indicator of the button will be illuminated at
20% intensity.
NOTE: Multiple memories can be activated at the same time – they will be merged using HTP(Highest Takes Precedence) protocol.
