Setup
- Connect to Device: Insert the USB connector of the headset into an available USB port on your desktop computer, laptop, or compatible tablet.

- Audio Settings: Once connected, verify that the HamiltonBuhl MACH-2 headset is selected as the default audio input (microphone) and output (speakers) device in your computer's sound settings.
Operating Instructions
- Wearing the Headset: Adjust the headband for a comfortable fit over your ears. The over-ear design provides sound isolation.

- Volume Control: Use the in-line remote control on the cable to adjust the listening volume.
- Microphone Mute: The in-line remote may also include a microphone mute switch. Refer to the specific remote design for its functionality.
Maintenance
- Cleaning: Wipe the headset surfaces with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Cable Care: The Dura-Cord is designed to be chew, kink, and knot-resistant. However, avoid excessive pulling or bending at the connection points to prevent internal damage.
- Storage: When not in use, store the headset in the provided anti-lice storage bag to protect it from dust and potential contaminants.
Troubleshooting
