HSW306-PT Six-Button Handset with USB and Lumbar Controls

The HSW306-PT is a replacement handset with six buttons, a USB port and lumbar controls for matching Theorem and Pride electric recliners and lift chairs, plus other brands using the same handset and control system. Choose by the complete handset reference, button functions and connection, not by chair brand or appearance alone.

This is the lumbar-button version. The separate HSW306E-PT listing identifies a leg-rest-button layout. Do not substitute one for the other without confirming the original chair's control system and wiring.

Model and features

• Applications: Matching Theorem and Pride electric recliners and lift chairs, plus other brands using the same part and control system
• Listed model reference: HSW306-PT
• Controls: six-button layout with listed lumbar controls
• USB port: listed; output rating is not confirmed
• Application: matching electric recliner and lift chair systems
• Connector: compare the complete original plug and cable arrangement; pin count and electrical ratings are not specified here

Compare each button icon and function with your original handset. A lumbar button does not add lumbar adjustment to a chair without the matching mechanism and control system.

Compatibility before ordering

Suitable for matching Theorem and Pride electric recliners and lift chairs, plus other brands using the same part and control system. This is not a universal handset for every model from those brands. Match the full model number, connectors and functions before ordering.

• Match the complete HSW306-PT reference against the original handset label or chair documentation.
• Compare all six buttons, including the lumbar-control icons and functions.
• Check the handset shape, USB opening, connector shape, keying, pin arrangement and cable route.
• Confirm the chair's control system supports this exact handset. Matching appearance or pin count alone does not establish electrical compatibility.

If the original model is unreadable or any detail differs, send clear photos of the handset front, rear label, plug and chair model or paperwork to CouchGuard, or call 1300 268 244 before ordering.

Replacing a matching handset

1. Unplug the chair from mains power and ensure it is stable and safe to access.
2. Photograph the original handset, connection and cable path before removal.
3. Follow the chair manufacturer's service instructions. Hold the plug body rather than pulling the wires.
4. Fit only a confirmed matching handset. Do not force connectors, alter the wiring or route cables near moving mechanisms and pinch points.
5. Restore power and test the controls from a safe position. Stop if any function differs from the chair's expected operation.

Use a qualified repair technician if access, wiring or compatibility is uncertain.

Check the fault before replacing parts

A non-responsive chair or failed lumbar function may result from the handset, wiring, control box, power supply or actuator. A replacement handset is not a guaranteed repair. Note which functions still work and seek assistance if the fault is unclear.

Frequently asked questions

What is the HSW306-PT?

It is a replacement six-button handset with USB and lumbar controls for matching Theorem and Pride electric recliner and lift chair systems, plus other brands using the same handset and control system.

Is this the lumbar or leg-rest version?

This HSW306-PT listing identifies the lumbar-button version. HSW306E-PT is separately listed with a leg-rest-button layout.

Can I replace HSW306E-PT with this handset?

No interchangeability is confirmed. Compare the original model, all button functions and chair control system before choosing either version.

Does it have USB?

Yes, a USB port is listed. Its output rating is not confirmed; consult the handset or chair documentation before connecting a device.

Will it fit every Theorem or Pride lift chair?

No. Match the full HSW306-PT reference, button layout, controller and original connector. It also suits other brands only when they use the same part and control system. Chair brand alone does not establish fit.

What connector does it use?

A specific pin count is not confirmed here. Compare clear photos of the complete original plug, keying and wiring arrangement before ordering.

Will a new handset fix a failed lumbar function?

Not necessarily. Wiring, control-box or actuator faults can produce similar symptoms. Diagnose the fault before purchasing a replacement handset.

What should I send for a compatibility check?

Send readable photos of the original handset front, rear model label and plug, plus the chair model details or paperwork and a description of any failed functions.
