4. Setup Guide
- Charge the Inductor Necklace: Before first use, fully charge the GSM Inductor Necklace using the provided USB charging cable and European charger. The charging indicator will show when it's fully charged.
- Insert SIM Card: Open the SIM card slot on the Inductor Necklace and carefully insert a standard Nano SIM card. Ensure it is correctly oriented as per the diagram on the device.
- Wear the Necklace: Place the Inductor Necklace around your neck, ensuring it is concealed under your clothing. The necklace acts as the primary communication hub.
- Position the Microphone: Connect the wired microphone to the designated port on the necklace. Route the microphone wire discreetly, for example, down your sleeve or under your collar, so the microphone is close to your mouth for clear audio input.
- Insert the Earpiece: Carefully place the Nano V6 earpiece deep into your ear canal. It should be completely invisible from the outside. You may need to gently shake your head or use a non-metallic tool to help it settle.
- Power On: Turn on the Inductor Necklace using its power button. It will automatically connect to the GSM network.

5. Operating Instructions
Once the system is set up and powered on, you can begin using it for communication:
- Making Calls: To initiate a call, you will need to dial the number using a connected mobile phone (if applicable, though the necklace supports direct SIM calls) or use the necklace's dialing function if available. For direct SIM calls, the necklace acts as a standalone phone.
- Receiving Calls: When a call comes in, the necklace will typically auto-answer or have a button to answer. Audio will be transmitted directly to the earpiece.
- Adjusting Volume: Use the volume controls on the Inductor Necklace to adjust the audio level in the earpiece.
- Using the Microphone: Speak softly or whisper into the wired microphone. Ensure the microphone is positioned correctly to pick up your voice clearly.
- Ending Calls: Press the designated button on the necklace to end a call.
6. Maintenance and Care
Proper maintenance ensures the longevity and optimal performance of your device:
- Cleaning the Earpiece: After each use, carefully remove the earpiece using the extractor bar or magnet. Clean any earwax or debris from the earpiece using a soft, dry cloth. Do not use liquids or harsh chemicals.
- Charging: Recharge the Inductor Necklace regularly, especially after prolonged use, to maintain battery health. Avoid overcharging.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective case when not in use.
- Water Resistance: The product is listed as 'Waterproof'. However, avoid submerging the device in water. 'Waterproof' typically refers to resistance against splashes or light rain, not full immersion.
