This article explains how to configure the Backpack Harness fit for an operator. Set the torso height first, then the load lifter slots. These settings stay set until the operator or fit changes.
Set the fit before mounting the GX1 and putting on the backpack. See Set up GX1 backpack.
Set the torso height before the load lifter slots, because load lifter position depends on torso height. Set both with the harness off the body.

Procedure
Each Shoulder Strap is adjusted the same way: release the current setting, move to the new slot, secure it, and check it holds. Set both straps to matching positions.
Step 1: Set the torso height
The selected slot must be at least five slots below the top-most slot.
At the torso height attachment point, release the Hook-and-Loop Adjustment Strap and guide the Retention Loop and strap through the slots until free.
Thread the strap and Retention Loop back through the selected slot.
Thread the Hook-and-Loop Adjustment Strap back through the Retention Loop, pull it firmly down, and secure it.
Verify the attachment is seated and does not move.
Repeat on the other Shoulder Strap at the same torso height.
The images below show the strap being released. To reattach at the new slot, reverse the steps shown.

Step 2: Set the load lifter slots
Release the Load Lifter Retention Tab from its current slot.
Push the tab through the selected slot and rotate it perpendicular to the Harness Frame.
Verify the tab is seated and does not move.
Repeat on the other Shoulder Strap at the same position.
The load lifters are tensioned later, once the backpack is worn. See Set up GX1 backpack.
The images below show the tab being released. To reattach at the new slot, reverse the steps shown.

Outcome
The Backpack Harness is configured for the operator. Both Shoulder Straps sit at the same torso height, and the load lifter slots are set evenly. The fit stays set until the operator or fit changes.
Important considerations
A poor backpack fit can cause back, shoulder, or neck strain and load instability during a scan. Re-check the fit when the operator or load changes. See Warnings and safety.
