3. Setup

3.1 Connecting the Headset

Locate the 4-pin female XLR connector on the headset cable.
Connect the 4-pin female XLR connector of the headset cable to the corresponding male XLR port on your intercom system or audio device. Ensure the connection is secure.

3.2 Adjusting for Comfort

Adjust the headband for a secure yet comfortable fit on your head.
Position the earcups over both ears, ensuring they fully enclose your ears for optimal sound isolation and comfort.
Adjust the flexible microphone boom arm so the microphone is positioned approximately 1 to 2 inches from your mouth.

4. Operating Instructions

4.1 Microphone Activation and Muting

The microphone is activated or muted by rotating the boom arm.
To Mute: Rotate the microphone boom arm upwards, away from your mouth.
To Activate: Rotate the microphone boom arm downwards, towards your mouth.
The boom arm has a 300-degree rotation range for this function.

4.2 Audio Monitoring

Ensure your audio device or intercom system is properly configured for audio output to the headset.
Adjust volume levels on your connected device as needed for comfortable listening.

5. Maintenance

5.1 Cleaning

To clean the headset's exterior, use a soft, dry cloth.
For the soft ear-pads, a slightly damp cloth with a mild soap solution can be used. Ensure no moisture enters the earcup components. Allow the ear-pads to air dry completely before using the headset.
Avoid using harsh chemicals or abrasive cleaners, as these can damage the headset's finish and materials.

5.2 Storage

Store the headset in a clean, dry environment away from direct sunlight and extreme temperatures.
Avoid wrapping the cable tightly around the headset, as this can cause stress and damage to the cable over time.

6. Troubleshooting

6.1 No Audio Output

Check Connections: Ensure all cable connections, especially the 4-pin XLR connector, are fully and securely seated in their respective ports.
Volume Settings: Verify that the volume levels on your connected intercom system or audio device are not muted and are set to an audible level.
Device Compatibility: Confirm that the headset is compatible with the audio device it is connected to.

6.2 Microphone Not Working

Microphone Position: Ensure the microphone boom arm is rotated downwards (towards your mouth) to the 'on' position.
Cable Integrity: Inspect the headset cable for any visible damage or kinks.
Test with Another Device: If possible, test the headset with another compatible audio device to determine if the issue lies with the headset or the connected equipment.

6.3 Poor Sound Quality

Cable Condition: Check the headset cable for any signs of damage that might affect audio transmission.
Earcup Seal: Ensure the earcups are properly seated around your ears to provide optimal noise isolation and sound delivery.
