Operating Instructions
Your Dowinx LS-6658 chair offers several adjustable features for personalized comfort:
1. Seat Height Adjustment
To adjust the seat height, locate the lever on the right side beneath the seat (often marked "LIFT"). While seated, pull the lever up to lower the seat. To raise the seat, stand up and pull the lever up. Release the lever at the desired height.
2. Backrest Recline
The backrest can be reclined from 90° (upright working position) to 135° (relaxed lounging position). Locate the recline lever on the left side beneath the seat (often marked "RCL"). Pull the lever up and lean back to recline. Release the lever to lock the backrest in place. To return to an upright position, pull the lever and lean forward.
3. Extendable Footrest
For added relaxation, pull the footrest out from beneath the seat. Extend it to your desired length. To retract, push it back under the seat until it is fully stored.
4. Massage Lumbar Support
The lumbar support cushion includes a massage function. Connect the USB cable, typically located at the back of the lumbar cushion, to a compatible USB power source (e.g., computer, power bank, USB wall adapter). The massage function will activate upon connection.
