attached to the patient. For instructions on electrode montage and impedance testing, please refer to section

2.6.8.1 Installing DataLink in combination with Orion Reclining, System 2000 Reclining, or System
2000 Comprehensive
When configuring a DataLink in combination with an Orion Reclining, a System 2000 Reclining, or a System
2000 Comprehensive chair, sometimes the DataLink board (minilab 1008) is detected first and becomes
board#0 in Instacal. This can conflict with the communication between the chair and the VisualEyes™
software.
