Inserting your Optimeye Device (S5, X4) into the Garment correctly is an important part of setting up your session, as an incorrect unit orientation can lead to inaccurate data and potential dropouts. 

Device Orientation

For the unit to function correctly it needs to be inserted into the pouch of the Garment as follows:

• The Antenna must be at the top, closest to the player's head
  
  
• The LED Lights must be facing outward

This ensures optimal data collection for your device.
