   • For USB connection: Plug the USB-A connector into an available USB 2.0 or 3.0 port on your computer (desktop or laptop).
   • For 3.5mm connection: Plug the 3.5mm jack into the audio port of your smartphone, laptop, or desktop computer.

4. Operating Instructions

4.1 In-line Control Unit

The in-line control unit (refer to Figure 2.3) provides convenient access to essential functions:

• Volume Control: Use the '+' and '-' buttons to adjust the listening volume.
• Microphone Mute: Press the microphone icon button to mute or unmute your microphone. A red indicator light on the button typically signifies that the microphone is muted.
• Call Management: The call button (often a phone icon) allows you to answer or end calls when used with compatible communication software.
• Integrated Busy Light: The light on the control unit acts as a 'do-not-disturb' sign, indicating when you are actively on a call to prevent interruptions.

4.2 Passive Noise Cancellation

The headset features passive noise cancellation, which physically blocks high-frequency background sounds, allowing you to focus on your calls and audio with greater clarity.

4.3 Adjustable Headband and Microphone

Adjust the headband to comfortably fit your head. Position the flexible microphone boom approximately 1-2 inches from your mouth for optimal voice pickup and clarity.

5. Maintenance

To ensure the longevity and optimal performance of your headset, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe down the headset and ear cushions. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the speaker grilles or microphone. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the headset in a clean, dry place away from extreme temperatures and direct sunlight. Avoid tangling the cables.
• Cable Care: Do not pull on the cable to disconnect the headset. Always grasp the plug firmly. Avoid sharp bends or kinks in the cable.
