3. Setup and Installation

1. Identify Connectors: The OPC-499 adapter has two input jacks for your aviation headset (typically a larger jack for headphones and a smaller jack for the microphone) and one output connector designed to plug into your compatible ICOM handheld radio.
2. Connect Headset: Insert the headphone plug from your aviation headset into the larger jack on the OPC-499 adapter. Insert the microphone plug from your aviation headset into the smaller jack on the OPC-499 adapter. Ensure both connections are secure.
3. Connect to Radio: Carefully align the adapter's output connector with the accessory port on your ICOM handheld radio (e.g., IC-A6, IC-A14, IC-A24). Push firmly until the connector is fully seated. Do not force the connection.
4. Power On Radio: Once the adapter and headset are connected, power on your ICOM handheld radio.

Note: Always ensure your radio is powered off before connecting or disconnecting accessories to prevent potential damage.

4. Operating Instructions

After successful setup, the OPC-499 adapter allows you to use your aviation headset for both listening and transmitting with your ICOM handheld radio.

• Receiving Audio: Audio from the radio will be routed directly to your headset's headphones. Adjust the volume on your ICOM radio as needed.
• Transmitting: To transmit, use the Push-To-Talk (PTT) button on your aviation headset or the PTT button on your ICOM radio, depending on your headset's configuration. Speak clearly into your headset microphone.
• Sidetone: Some aviation headsets provide sidetone (hearing your own voice in the headset during transmission). This function is dependent on your headset, not the OPC-499 adapter.

5. Maintenance

The ICOM OPC-499 headset adapter requires minimal maintenance to ensure long-term performance.

• Cleaning: Use a soft, dry cloth to wipe the adapter's exterior. Avoid using harsh chemicals, solvents, or abrasive cleaners.
• Storage: Store the adapter in a clean, dry environment away from extreme temperatures and direct sunlight when not in use.
• Inspecting Connections: Periodically inspect the connectors for any signs of wear, corrosion, or damage. Ensure pins are straight and clean.
• Avoid Stress: Do not pull on the cable to disconnect the adapter. Always grasp the connector housing. Avoid bending or twisting the cable excessively.
