When updating your Releve fixture from version 1.0.0 to 1.0.1, you will want to make sure to re-calibrate your Pan and Tilt.
To do this, you will want to go into the Advanced Menu > Control & Calibrate > Pan/Tilt.
From this menu, you will want to run Auto-Recall for both Pan and Tilt.
After the process is complete, your fixture should be fully calibrated and accurate for operation.
Contact ETC Technical Services if you have additional questions.
