- Ensure the Ossur AD-121AG Cold Rush Therapy System is turned off and disconnected from any power source.
- Connect the barrel connector end of the AC adapter cable firmly into the power input port on your Ossur AD-121AG Cold Rush Therapy System.
- Plug the 2-pin main power connector of the AC adapter into a standard electrical wall outlet. The adapter is designed for worldwide use with input voltages ranging from 100V to 240V AC.

Operating Instructions
The AC adapter provides continuous and stable power to your Ossur AD-121AG Cold Rush Therapy System when connected to a suitable power source.
- LED Indicator: The integrated LED light on the adapter serves as a visual confirmation that the adapter is receiving power from the wall outlet and is actively supplying power.
- Intelligent Switching Circuit: This adapter incorporates an intelligent switching circuit. If the connected device has a rechargeable battery, this circuit is designed to recognize a fully charged battery and automatically switch to a safe mode, preventing overcharging and extending battery life.
- Safety Features: For your safety and the protection of your device, the adapter is equipped with short circuit protection, which automatically cuts off power in the event of an electrical short.
Important: Always ensure the adapter's connector is securely fitted into the device's power port to prevent intermittent power supply or potential damage.
Maintenance
Proper care and maintenance will prolong the life of your AC adapter.
- Keep the adapter and its cables clean and free from dust and debris.
- Avoid bending, twisting, or kinking the cable excessively, as this can damage internal wires and lead to malfunction.
- Store the adapter in a cool, dry place when not in use, away from direct sunlight or heat sources.
- Do not expose the adapter to moisture, liquids, or extreme temperatures.
Cleaning: Disconnect the adapter from the power outlet and the device before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners, solvents, or abrasive materials.
Troubleshooting
If you encounter issues with your AC adapter, refer to the following troubleshooting guide:
No Power to Device
- Check Connections: Ensure both the barrel connector into the Ossur system and the 2-pin plug into the wall outlet are securely and fully inserted.
- Verify Outlet: Test the wall outlet with another known working device (e.g., a lamp) to confirm it is functional and receiving power.
- LED Indicator: Check if the LED indicator on the adapter is illuminated. If it is not lit, the adapter may not be receiving power or could be faulty.
Loose Connection
- If the adapter's barrel connector feels loose when plugged into the Ossur AD-121AG Cold Rush Therapy System, double-check that it is the correct adapter model. A loose connection can lead to intermittent power supply or prevent the device from powering on.
- Avoid putting strain on the connection point, as this can exacerbate looseness or cause damage over time.
Adapter Overheating
- While the adapter is designed to operate efficiently without excessive heat, if it feels unusually hot to the touch, immediately disconnect it from both the wall outlet and the device.
- Ensure adequate ventilation around the adapter. Do not cover it with cloths, blankets, or place it in enclosed spaces during operation.
If troubleshooting steps do not resolve the issue, please contact customer support for further assistance.
