Nds surgical imaging Zero Wire Duo User Manual page 19

Test results indicate that ZeroWire achieves a better signal-to-noise ratio when the Tx and Rx are oriented
at certain angles relative to one another.
Optimum link quality is achieved when the Tx and Rx are aligned at 0° relative to each other.
Acceptable link quality is achieved when the Tx and Rx are aligned at angles between 0 to 45°, 130° and
180° relative to each other.
Aligning the Tx and Rx at 90° relative to each other provides the least acceptable link quality.
