SM820L: delivery record
On this page
The SM820L record describes one new hand-control assembly. The first two photographs show a black wired handset with a coiled cable and a connector with a metal collar, then its display and button face. No readable manufacturer, SM820L model label or R720 marking appears in these views, so the title’s fitment reference requires confirmation.
Identification and delivery details
The rear view shows a rectangular recessed panel and the attached cable. The front view shows a dark display window, buttons with Chinese legends, directional controls and an OK key. The display is not shown operating, and no button response is demonstrated.
The February 4, 2026 manual entry explicitly records one piece, new condition and 0.5 kg. It does not state a manufacturer, revision or warranty, and the weight basis is unspecified. A visible handset and cable do not establish a complete factory packing inventory.
The source description associates SM820L with an R720 massage-chair hand-control assembly. The reviewed photographs do not verify that reference against a full unit label or a connected chair. The connector’s external appearance does not establish its pin count, assignment, supply requirements or communication protocol.
No powered function, chair compatibility or service result was reviewed. Request the existing chair and handset identities, the offered revision and applicable compatibility documentation before selecting a replacement. This article does not supply installation steps or infer function from printed button legends.
