Verification

1. Verify the TCR door opens and closes smoothly. Refer to TCR Door Alignment and Adjustment
2. Power cycle the Panther instrument.
3. Using the Panther service software, verify the TCR Door lock is operational. The door sensor should report as “Closed” when the door is locked and also when the door is pulled gently. Adjust the front cover and/or magnet screw if necessary to correct the sensor readings.
4. Verify the TCR door lock is functional in the Panther GUI.
