Setup Instructions
Follow these steps to properly set up your SOUNDLINK CS44 Universal Programming Cable for use:
- Prepare Your Equipment: Ensure you have your programmable BTE hearing aids, a compatible hearing aid programmer (e.g., Hi-Pro, NoahLink, SpeedLink, USB Hi-Pro), and the necessary programming software installed on your computer.
- Connect to Programmer: Identify the larger connector end of the CS44 cable. This end connects to your hearing aid programmer. Insert it firmly into the designated port on your programmer.
- Connect to Hearing Aid: Identify the smaller, 4-pin connector end of the CS44 cable. This end connects to your BTE hearing aid. Carefully align the pins and insert the connector into the programming port of your hearing aid. Ensure a secure connection.
- Connect Programmer to Computer: If your programmer is not already connected, connect it to your computer using its dedicated USB or serial cable as per the programmer's instructions.
- Launch Software: Open the hearing aid programming software on your computer. The software should detect the connected programmer and hearing aid.
The CS44 cable is compatible with most hearing aid manufacturers that adopt CS44 as a standard programming cable, including but not limited to ReSound, Siemens, Oticon, Audio Services, Rexton, and Interton.

Operating Instructions
Once the SOUNDLINK CS44 cable is correctly connected between your hearing aid, programmer, and computer, you can proceed with programming:
- Software Recognition: Verify that your hearing aid programming software recognizes both the programmer and the connected hearing aid. This is usually indicated by a status message within the software.
- Load Hearing Aid Profile: Within the software, load the specific profile or settings for the hearing aid you are programming.
- Adjust Settings: Use the software interface to make the desired adjustments to the hearing aid's settings, such as volume, frequency response, noise reduction, and other personalized parameters.
- Save and Transfer: After making all necessary adjustments, save the new settings within the software. Then, initiate the transfer process to write these settings to the hearing aid. Follow the on-screen prompts provided by your programming software.
- Disconnect Safely: Once the programming process is complete and confirmed by the software, safely disconnect the cable from the hearing aid and programmer. It is recommended to close the programming software before disconnecting hardware.
The CS44 cable acts as a data conduit; all programming functions are performed through the dedicated hearing aid programming software.
Maintenance
Proper care and maintenance will extend the life of your SOUNDLINK CS44 Universal Programming Cable:
- Storage: Store the cable in a clean, dry place away from direct sunlight and extreme temperatures. Avoid kinking or tightly coiling the cable.
- Cleaning: If necessary, gently wipe the cable and connectors with a soft, dry, lint-free cloth. Do not use liquid cleaners or solvents, as these can damage the cable or connectors.
- Handling: Always grasp the connectors when plugging or unplugging the cable, rather than pulling on the cable itself, to prevent damage to the internal wires.
- Inspection: Periodically inspect the cable for any signs of wear, fraying, or damage to the connectors. Discontinue use if any damage is observed.
Troubleshooting
If you encounter issues while using your SOUNDLINK CS44 Universal Programming Cable, consider the following troubleshooting steps:
- Cable Not Recognized:
- Ensure both ends of the CS44 cable are securely connected to the hearing aid and the programmer.
- Verify that the programmer itself is correctly connected to the computer and its drivers are installed.
- Try restarting the programming software and/or your computer.
- Check if the hearing aid is powered on and functioning correctly.
- Programming Errors:
- Confirm that you are using the correct programming software version for your specific hearing aid model.
- Ensure the hearing aid's battery is sufficiently charged.
- Temporarily disable any antivirus or firewall software that might interfere with the programming software.
- Intermittent Connection:
- Inspect the cable and connectors for any visible damage or bent pins.
- Ensure the cable is not under tension or being moved during the programming process.
If problems persist, consult the documentation for your specific hearing aid programmer and programming software, or contact SOUNDLINK customer support.
