Now that you’re anchored and you’ve attached an accessory, changing resistance is as simple as twisting the VECTOR cap. Always make sure the cap is closed before twisting it to change resistance.
Start by twisting the cap so that the arrow points to Level 1 (a single horizontal blue line). Pull against the resistance. At Level 1, 4 tubes are engaged. Return to the starting point with the cap closed. Twist the cap to Level 2 (2 horizontal blue lines) and see how that feels. At Level 2, 6 tubes are engaged. Return to the starting point with the cap closed. Twist the cap to Level 3 (3 horizontal blue lines) and see how the resistance increases. At Level 3, all 8 tubes are engaged.
