Setup Guide: How to Pair and Use the SM-3P

Setting up the device is straightforward. First, fully charge the unit using the USB-C port before pairing. Next, turn on the accessory and place it near the compatible GN Hearing hearing aids. Use the pairing procedure in the hearing aid app or follow the hearing aid pairing button sequence described in the user guide for your specific model. If using Auracast broadcast audio, activate broadcast mode and select the desired source from the hearing aid app or compatible interface.

For audio streaming, connect the external source through the line-in mini-jack, FM connector, or other supported input. Adjust the microphone placement so the microphone points toward the primary speaker for best speech pickup. If the signal is weak, reduce distance, confirm the hearing aids are in range, and make sure the accessory and hearing aids are both charged.

Safety tips are important during setup. Keep the device away from water, excessive heat, and unauthorized charging accessories. Do not attempt to open the unit or use damaged cables. If pairing fails, restart both devices, move them closer together, and repeat the process. If the accessory is not recognized, check that the hearing aids are compatible with the GN Hearing Multi-Mic+ Microphone & Audio Streamer SM-3P.

Troubleshooting Common Problems

If the device does not power on, the battery may be depleted. Charge it fully and try again. If audio is distorted or drops out, move closer to the speaker or reduce interference from other wireless devices. If the hearing aids do not connect, delete the old pairing, restart both devices, and pair again from scratch.

• No sound: Check volume settings, hearing aid program selection, and battery status.
• Poor microphone pickup: Reposition the device closer to the talker and confirm the correct microphone mode.
• Intermittent streaming: Stay within the recommended 25-meter range and avoid thick walls or heavy signal interference.
• App control not working: Update the hearing aid app and reconnect the accessory.
• Charging issue: Inspect the USB-C cable and charging port for debris or damage.

No specific public error-code system is widely documented for this accessory, so most issues are resolved through pairing resets, charging checks, or app updates.

Warranty coverage is commonly limited by region and seller policy, with support usually handled through the hearing care provider or authorized GN Hearing distributor. For help, contact the provider that supplied the device or the brand’s official support channel for your market.
