Setup

1. Unpack the Headset: Carefully remove the AC-200 headset and any included accessories (e.g., ear cushions) from its packaging.
2. Inspect for Damage: Before first use, visually inspect the headset, cables, and plugs for any signs of damage. Do not use if damaged.
3. Adjust Headband: Extend or retract the stainless steel headband slides to fit your head comfortably. The earcups should fully cover your ears without excessive pressure.
4. Position Microphone: Adjust the flexible microphone boom so that the M-65 microphone is approximately 0.5 to 1 inch (1.2 to 2.5 cm) from your mouth, slightly to the side to avoid direct breath. Ensure the acoustic mic muff is securely in place.
5. Connect to Equipment: Insert the two 3.5mm audio plugs into the corresponding jacks on your aviation equipment (e.g., aircraft intercom panel). Ensure a firm connection.

Operating Instructions

Volume Control:

The AC-200 headset features an integrated volume control knob on one of the earcups. Rotate the knob clockwise to increase the listening volume and counter-clockwise to decrease it. Adjust the volume to a comfortable level that allows clear reception of audio without distortion.

Microphone Usage:

The M-65 microphone is designed for clear voice transmission. Ensure it is positioned correctly (0.5 to 1 inch from your mouth) and that the mic muff is in place to reduce breath noise. Speak clearly and at a normal conversational volume. The active filtering chip will help optimize your voice for transmission.

Maintenance

• Cleaning:
  • Wipe the headset's exterior surfaces with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
  • Clean the ear seals and mic muff regularly. Replace them if they become worn or damaged to maintain comfort and performance.
• Storage:
  • Store the headset in a clean, dry place, away from direct sunlight and extreme temperatures.
  • Avoid coiling the cables tightly to prevent damage. The cable features are retractable, so ensure they are not stressed.
  • If possible, store in a protective bag or case to prevent dust accumulation and physical damage.
• Inspection: Periodically inspect the cables, plugs, microphone boom, and headband for any signs of wear, fraying, or damage. Address any issues promptly.
