3. Fitting the Hearing Aids
Select the ear-tip (dome) size that provides the most comfortable and secure fit in your ear canal. The correct fit is crucial for optimal sound quality and to prevent feedback. Gently insert the hearing aid into your ear canal until it feels snug and comfortable.

Operating Instructions

Your Nano First Ear Pro CIC hearing aids offer four distinct program settings to adapt to various listening environments. Use the button control on the device to cycle through these settings:
- Quiet: Ideal for situations such as watching TV or listening to music.
- Conversation: Optimized for typical quiet conversational settings.
- Outdoor: Provides less amplification of wind sounds and enhances other natural sounds.

Maintenance
1. Charging
Always ensure your hearing aids and charging case are adequately charged. Place the hearing aids in the charging case when not in use to keep them powered and protected. A fully charged case can provide three full recharges for your hearing aids.
2. Cleaning
Regular cleaning is essential for optimal performance and hygiene. Use a soft, dry cloth to wipe the hearing aids daily. Remove earwax and debris from the ear-tips using the provided cleaning tool. Do not use water or cleaning solutions directly on the hearing aids.
3. Storage
Store your hearing aids in their charging case when not in use. Keep them in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
If you experience issues with your Nano First Ear Pro CIC hearing aids, consider the following:
- No Sound or Low Volume: Ensure the hearing aids are fully charged. Check if the ear-tips are clean and free of wax buildup. Adjust the volume setting.
- Feedback (Whistling Sound): This often indicates an improper fit. Try a different size ear-tip for a more secure seal in your ear canal. Ensure the hearing aid is fully inserted.
- Intermittent Sound: Check for a secure connection in the charging case. Ensure the hearing aids are clean and dry.
- Discomfort: If you experience discomfort, try a smaller ear-tip size. If discomfort persists, discontinue use and consult a professional.
