4. Operating Instructions

4.1. Ergonomic Chair Adjustments

The EC100 chair offers multiple adjustment features to customize your seating experience:

• Seat Height Adjustment: Locate the lever on the right side beneath the seat. Pull the lever up to raise the seat; release to lock. To lower, sit on the chair and pull the lever up.
• Tilt Mechanism: The chair features a two-mode locking tilt mechanism. Use the lever on the left side to unlock the tilt for rocking or lock it at your desired angle (90° for working, 130° for relaxing).
• Tilt Tension: Rotate the round knob under the seat (usually at the front) to adjust the tension of the tilt mechanism. Turn clockwise to increase tension, counter-clockwise to decrease.
• 2D Armrests: The armrests can be adjusted in two dimensions:
  • Height Adjustment: Press the button on the side of the armrest and move it up or down. Release the button to lock.
  • Rotation: The armrest pads can typically be rotated inwards or outwards to support various postures.
• Rotating Headrest: The headrest can be adjusted for height and angle. Gently push or pull to adjust its position to support your neck and head.
• Adaptive Lumbar Support: The S-shaped dual-back design provides adaptive lumbar support that conforms to your spine. No manual adjustment is typically needed for this feature.

The adjustable standing desk features an electric lifting mechanism and a control panel for easy height adjustments:

• Height Adjustment: Use the Up and Down arrow buttons on the control panel to raise or lower the desk to your desired height.

  1. Adjust the desk to your desired height.
  2. Press the "M" or "Set" button (if available) followed by the desired memory button (e.g., "1"). The desk will beep or flash to confirm the setting is saved.
  3. To recall a saved height, simply press the corresponding memory button.
• Anti-Collision Feature: The desk may have an anti-collision system that stops and slightly reverses movement if it encounters an obstruction during adjustment.
