3. Verify that the X-flex cables will not interfere with pipettors traveling in an X-direction.
4. Install Panther System firmware.

Verification

Warning—Shut off the system immediately if Pipettors do not home in the correct direction or move to the incorrect Z-travel position. Perform system setup to install firmware.

1. Verify Pipettors initialize properly (Pipettors should move up in the Z-direction during homing).
