This Six Button 7 pin remote controller is suitable for power recliners or lift chairs that has three linear actuator motors. It replaces most of the HSW306 hand wands made by HHC/MotorMotion. Features:  Six buttons Seven pins round male plug  With a USB charging port With backlit Important! This remote control comes in two versions to match the functionality of your reclining chair. The key difference is how the backrest and footrest recline: Linked Recline (Standard Version):  If pressing the backrest recline buttons also controls the footrest position (both recline together), then choose the Standard Version of this remote. Independent Recline (Version B):  If your chair has separate controls for the backrest and footrest (incline and decline buttons for each), then choose Version B of this remote. Selecting the Right Version: To ensure proper operation, please choose the version that matches your original remote's functionality. Using the wrong version may cause unintended behavior (e.g., selecting the standard version for a Version B remote might cause the calf rest to rise with the backrest). Notes:  The plug of this remote controller is 7 pin. Some HSW306 remotes may use a 5-pin plug, which this remote cannot replace. The backlight is not constantly lit; it illuminates only when you press the buttons. In rare cases, due to potential variations in wiring sequences, the buttons might function differently after replacing your original remote (e.g., the headrest control button might control the lumbar support instead). We suggest purchasing a 7-pin wire harness together in case the cable is not long enough. Please click here.
