- Attach the Backrest: With the seat base upright, slide the backrest into the metal slots on the rear of the seat base. Push down firmly until you hear a click, indicating it is locked into place.
- Connect Power (for Massage Function): Locate the power cable extending from the chair. Connect it to the provided power adapter, then plug the adapter into a standard electrical outlet.

Operating Instructions
Reclining Function
The DUMOS Recliner Chair offers adjustable reclining positions from 90° to 160° and an extendable footrest from 0° to 90°.
- To Recline: Lean back gently while pushing on the armrests. The backrest will recline, and the footrest will extend simultaneously. Continue to lean back until you reach your desired angle.
- To Return Upright: Lean forward and push down on the footrest with your legs. The footrest will retract, and the backrest will return to its upright position.

Massage Function
Your recliner is equipped with 8 massage modes for personalized comfort. The massage function is controlled via the wired remote control located in the side pocket.
- Power On/Off: Press the 'Power' button on the remote to activate or deactivate the massage function.
- Select Mode: Use the 'Mode' button to cycle through the 8 available massage modes.
- Adjust Intensity: Use the 'Intensity' buttons (+/-) to increase or decrease the massage intensity.

Maintenance
Proper care will help maintain the appearance and functionality of your recliner.
- Cleaning: The PU leather upholstery can be wiped clean with a damp cloth. For tougher stains, use a mild soap solution and wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Mechanism Care: Periodically check all bolts and screws to ensure they are tight. Lubricate moving parts of the reclining mechanism if they become stiff or noisy (use a silicone-based lubricant).
- General Care: Avoid direct sunlight exposure for prolonged periods to prevent fading. Keep pets from scratching the upholstery.
