5. Setup

- Connect Headset: Plug your ICOM HS-94 or HS-95 headset into the appropriate jack on the VS-1 unit. Ensure the connection is firm.
- Connect to Transceiver: Plug the two-pin connector cable from the VS-1 unit into the external speaker/microphone jack(s) on your compatible ICOM transceiver. Refer to your transceiver's manual for the exact port location.
- Secure Unit: Use the clip on the back of the VS-1 unit to attach it to your clothing, belt, or a convenient location for easy access to the PTT button.

6. Operating Instructions
The VS-1 unit supports both Push-To-Talk (PTT) and Voice Operated Transmit (VOX) functions.
6.1. Push-To-Talk (PTT) Operation
- Ensure your transceiver is powered on and set to the desired channel.
- To transmit, press and hold the large grey PTT button on the VS-1 unit. Speak clearly into your headset microphone.
- Release the PTT button to stop transmitting and return to receive mode.
6.2. Voice Operated Transmit (VOX) Operation
For VOX operation, your ICOM transceiver must support VOX functionality and be configured correctly. The VS-1 unit acts as an interface for the headset to enable this feature.
- Refer to your transceiver's instruction manual for details on enabling and adjusting VOX sensitivity and delay settings.
- Once VOX is enabled on your transceiver, speaking into your headset microphone will automatically initiate transmission without needing to press the PTT button.
- Adjust the VOX sensitivity on your transceiver to prevent accidental transmissions from background noise or to ensure your voice consistently activates transmission.
7. Maintenance
Proper maintenance ensures the longevity and reliable performance of your VS-1 unit.
- Cleaning: Wipe the unit with a soft, dry cloth. Do not use abrasive cleaners, solvents, or harsh chemicals.
- Storage: Store the unit in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Cable Care: Avoid sharply bending or twisting the cable. Do not pull on the cable to disconnect the unit; always grasp the plug.
8. Troubleshooting
If you encounter issues with your VS-1 unit, refer to the following common problems and solutions:
- No Audio / Cannot Transmit:
- Ensure all connections (headset to VS-1, VS-1 to transceiver) are secure.
- Verify that your transceiver is powered on and functioning correctly.
- Check your transceiver's settings for external microphone/headset activation.
- PTT Button Not Working:
- Confirm the VS-1 is fully plugged into the transceiver.
- Test with a different compatible headset if available to rule out headset issues.
- VOX Not Activating / Activating Too Easily:
- Adjust the VOX sensitivity and delay settings directly on your ICOM transceiver. Refer to your transceiver's manual for specific instructions.
- Ensure the headset microphone is positioned correctly near your mouth.
If problems persist after attempting these solutions, contact ICOM customer support.
