3. Product Overview and Components

The Neosonic MX-RIC hearing aids utilize a Receiver-in-Canal (RIC) design, where the speaker (receiver) is placed directly in the ear canal, connected by a thin wire to the main unit behind the ear. This design offers several advantages:

• Superior Sound Quality: The receiver's proximity to the eardrum provides clearer sound with less distortion.
• Reduced Feedback: Separation of microphone and speaker minimizes whistling.
• Comfort and Discretion: The small, lightweight unit behind the ear and thin wire make it less noticeable.
• Enhanced Airflow: More open ear canal design can improve comfort.

4.2 Selecting and Attaching Ear Domes

Choose an ear dome size that provides a comfortable and secure fit in your ear canal. A proper fit is crucial for optimal sound quality and to prevent feedback.

• Gently push the selected ear dome onto the receiver (speaker) at the end of the thin wire until it is securely attached.

4.3 Inserting the Hearing Aids

1. Hold the main unit behind your ear.
2. Gently guide the ear dome into your ear canal until it sits comfortably and securely.
3. Adjust the thin wire so it rests discreetly along the curve of your ear.

5. Operation

5.1 Power On/Off and Mode Selection

The main unit behind your ear features buttons for control:

• Power/Mode Button: Press and hold to power the device on or off. Short presses cycle through available sound programs/modes.
• Volume Up Button: Increases the listening volume.

5.2 Dual Microphone Noise Cancellation

The Neosonic MX-RIC is equipped with a dual microphone system, featuring both a front and a rear directional microphone. This advanced setup enhances sound clarity by:

6.1 Cleaning Your Hearing Aids

Regular cleaning helps maintain performance and extends the lifespan of your devices.

• Use the provided cleaning tool to gently remove any wax or debris from the ear domes and receiver.

• Ensure the charging contacts on both the hearing aids and the charging station are clean and dry.

6.2 Water Resistance (IP65 Rating)

The Neosonic MX-RIC hearing aids have an IP65 rating, indicating they are protected against dust ingress and low-pressure water jets from any direction. This means they are splash-resistant and can withstand:

• Rainy conditions.
• Sweating during physical activities.

Important: The IP65 rating does not mean the devices are waterproof. Do not submerge them in water or expose them to high-pressure water streams.
