Setup

Before using your Zulu 4 headset, ensure it is properly connected and configured.

Connecting to Aircraft Power (Panel Power 6-Pin Plug)

  1. Locate the 6-pin Lemo connector on your aircraft's audio panel.
  2. Align the headset's 6-pin plug with the aircraft's receptacle.
  3. Gently push the plug into the receptacle until it clicks securely into place. This connection provides power to the headset and integrates it with the aircraft's intercom system.

Bluetooth Pairing

The Zulu 4 features dual Bluetooth connectivity, allowing two devices to be paired simultaneously.

  1. Ensure your headset is powered on.
  2. Activate Bluetooth on your mobile device (e.g., smartphone, tablet).
  3. On the headset's control module, press and hold the Bluetooth button until the indicator light flashes, indicating pairing mode.
  4. On your device, select "Zulu4_XXXX" (where XXXX is a unique identifier) from the list of available Bluetooth devices.
  5. Once connected, the indicator light on the control module will change to a steady blue.
  6. Repeat the process for a second device if desired.

Operating Instructions

Wearing the Headset

Place the headset on your head so that the ear seals fully enclose your ears. Adjust the headband for a comfortable, secure fit. The FrameFit™ ear seals are designed to accommodate eyeglasses or sunglasses without compromising the acoustic seal.

Active Noise Reduction (ANR)

The Active Noise Reduction (ANR) system automatically engages when the headset receives power from the aircraft's 6-pin Lemo connector, providing a quieter listening environment.

Using Bluetooth Audio

Once paired, you can stream audio from your connected devices. The headset prioritizes intercom and radio communications, automatically muting or lowering Bluetooth audio during critical transmissions.

Maintenance

Proper maintenance ensures the longevity and performance of your Zulu 4 headset.

  • Cleaning: Use a soft, damp cloth to clean the exterior surfaces. Avoid harsh chemicals or abrasive materials.
  • Ear Seals: Periodically inspect ear seals for wear and tear. Replace them if they become cracked or lose their cushioning to maintain optimal comfort and ANR performance.
  • Cable Care: Avoid sharp bends or excessive pulling on the cables. Store the headset in its protective case when not in use to prevent damage to the cables and connectors.
  • Storage: Store the headset in a cool, dry place, away from direct sunlight and extreme temperatures.

Troubleshooting

If you encounter issues with your Zulu 4 headset, consider the following common solutions:

  • No Audio/Intermittent Audio:
    • Ensure the 6-pin Lemo plug is fully seated in the aircraft's receptacle.
    • Check the volume controls on the headset and the aircraft's audio panel.
    • Verify the aircraft's intercom system is functioning correctly.
  • Bluetooth Connectivity Issues:
    • Ensure Bluetooth is enabled on your device and the headset is in pairing mode.
    • Try unpairing and re-pairing the device.
    • Ensure no other devices are interfering with the Bluetooth connection.
  • Poor Microphone Clarity:
    • Adjust the microphone position to be 1/4 inch from your lips.
    • Check the mic gain setting on the control module.
    • Ensure the microphone windscreen is clean and properly installed.
