HSW305-B-PT Five-Button Handset for Theorem and Pride

The HSW305-B-PT is a replacement handset listed with five buttons, headrest adjustment, chair up/down controls, a heat button and a USB port. It is suitable for matching Theorem and Pride electric recliners and lift chairs, plus other brands using the same handset and control system. It is not a universal remote for every Theorem or Pride chair.

Model and features

• Compatible applications: matching Theorem, Pride and other-brand chair control systems
• Model reference: HSW305-B-PT
• Button count: five
• Listed controls: headrest adjustment, chair up/down and heat
• USB port
• Connection: compare the original cable connector

Match each button icon and function with the original handset. A heat button does not establish heat compatibility with a chair that lacks the matching heat system, and a similar handset shape does not establish matching wiring.

Compatibility before ordering

Suitable for matching Theorem and Pride electric recliners and lift chairs, plus other brands using the same part and control system. Match the full model number, connectors and functions before ordering.

Compare the complete HSW305-B-PT reference, five-button layout, headrest and heat controls, USB opening, handset shape and cable connection. Other HSW-series handsets can have different functions and wiring; do not select a substitute by brand or appearance alone.

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

Replacing a matching handset

1. Switch off and unplug the chair from mains power. Ensure it is stable and safe to access.
2. Photograph the original control, cable route and connector before disconnecting anything.
3. Follow the chair manufacturer's instructions for removal. Hold the plug body rather than pulling the wires.
4. Fit only a confirmed matching handset. Do not force connectors, alter wiring or route the cable near moving mechanisms or pinch points.
5. Restore power and test the chair controls from a safe position. Stop if operation differs from the expected functions.

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

Check the fault before replacing parts

A failed movement or heat function can result from the handset, wiring, control box, power supply or the relevant chair component. A new handset is not a guaranteed repair. Note which functions still work and seek assistance if the cause is unclear.

Frequently asked questions

What is the HSW305-B-PT?

It is a replacement five-button handset for matching Theorem and Pride electric recliner and lift-chair systems, plus other brands using the same handset and control system, with headrest, chair up/down and heat controls plus USB.

How many buttons does it have?

The listing specifies five buttons. Compare every icon and function against your original control.

Does it have a heat button?

Yes, heat control is listed. The chair must already have the matching compatible heat system; this handset does not establish compatibility with other heating equipment.

Does it include USB?

A USB port is listed. Consult the handset or chair documentation for its output rating before connecting a device.

Will it fit any Theorem or Pride lift chair?

No. Match HSW305-B-PT, the full button layout, original cable connector and chair control system before ordering. It can also suit other brands using the same part and control system; chair brand alone does not establish fit.

Can I select it by appearance alone?

No. Similar-looking HSW-series handsets can have different functions and wiring. Match the complete model, controls and connection.

Will a replacement handset fix a chair that does not work?

Not necessarily. Power-supply, wiring, control-box or other component faults can cause similar symptoms. Identify the fault first.

What do I need for a compatibility check?

Send clear photos of the original handset front, rear label, plug and chair model details. Include any paperwork and describe which functions work or have failed.

Before You Buy a Replacement Part

Replacement parts can look similar while having different model numbers, dimensions, connectors or mounting points. Before ordering:

• Check the original part for a manufacturer label, model number or part number.
• Compare the connector type, dimensions and mounting points with the product listing.
• Check the product description and compatibility guidance carefully.
• Contact CouchGuard with clear photos if you are unsure which part you need.

Additional Checks for Electrical Parts

• Check that the green light on the power supply is on.
• Check the leads and connections for visible damage.
• Check whether the switch is faulty.
