Environmental Noise Cancellation (ENC)

The Callez 702TA headset utilizes dual microphones and advanced ENC technology with an A8 algorithm to effectively reduce background noise. This ensures that your voice is transmitted clearly to the other party, even in noisy environments.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the headset. Do not use liquid cleaners or solvents.
• Storage: Store the headset in a cool, dry place when not in use. Avoid extreme temperatures.
• Cable Care: Avoid sharp bends or excessive pulling on the USB cable to prevent damage.
• Ear Pads: The memory foam ear pads are designed for durability, but gentle handling will prolong their lifespan.

Troubleshooting

No audio or microphone not working:

• Ensure the USB-A connector is fully inserted into the port.
• Check your computer's sound settings to ensure the Callez 702TA headset is selected as the default playback and recording device.
• Verify that the microphone is not muted using the inline control button (red light indicates mute).
• Adjust the volume using the inline controls and your computer's system volume.
• Try connecting the headset to a different USB port or another computer to rule out port or system issues.

Poor microphone sound quality or others cannot hear me clearly:

• Ensure the microphone boom is positioned correctly, approximately 1-2 inches from your mouth.
• Check your application (e.g., Zoom, Teams) microphone settings to ensure the Callez 702TA is selected and its input volume is adequate.
• The microphone has high directionality for noise cancellation. Ensure the microphone capsule is pointed towards your mouth. If it's slightly off, your voice might not be picked up effectively.
• Test the microphone in a quiet environment to isolate potential background noise issues.

Inline control buttons are not responding:

• Ensure the headset is properly connected to your computer.
• Restart the application you are using (e.g., communication software).
• For call answer/end functions, ensure the application supports HID (Human Interface Device) controls from the headset.
