FITTING & WEARING INSTRUCTIONS
<Attaching the Eartips>
1. The ACUITY comes with two sets of Eartips in Mimi, small, medium &
large.
It is recommended to try the dierent options, since the size of your
ear canals might not be the best guide. Often a smaller Eartip will t
better because it can go in deeper or a larger one might be more
comfortable and still provide proper occlusion.
When you insert the Eartip, aim it forward and up, to match the angle
of the ear canal. Then try dierent angles with dierent size Eartips, to
maximize comfort and seal.
Proper Eartip insertion will ensure the very best sound quality, mini-
mize the amount of volume required, prevent leakage and avoid
feedback (will emit a whistling sound if not tted properly).
2. Attach the Eartip to the nozzle of the ACUITY earphone on one side by
gently pulling to cover it.
※ Do not pull the Eartip excessively when you attach or detach it
because it may tear.
3. Follow the same procedure for the other side.
<Earphones>
How deep you insert the earphones will also aect not only the seal, but
the quality of the sound, because not all Earphones are the same, so try
dierent depths as well to get the most out of your listening experience.
Place the device around your neck and under your shirt collar, to avoid
rubbing up against objects and reduce noise due to friction.

The Hear+Hi Acuity is a wireless stereo assistive hearing amplified earphone system designed to enhance hearing and provide a personalized audio experience. It functions as both an audio streaming device for calls and music, and a sophisticated hearing aid with advanced sound processing capabilities. The device is not intended for users under 18 years of age, and it is strongly recommended to consult a hearing healthcare professional for any hearing loss conditions, especially a licensed physician or ear specialist, before use.

Function Description:

The core function of the Acuity is to amplify and process sound to assist individuals with hearing loss. It utilizes advanced 8-Channel DSP (Digital Signal Processing) for precise amplification and wireless streaming, ensuring high-quality sound delivery. The device features dual microphones, which are crucial for capturing sound from the environment and for noise cancellation, contributing to clearer hearing in various settings.

A key feature is its personalized and customized hearing app, available on both iOS and Android platforms. This app allows users to perform a hearing test and adjust the device's volume modes according to their specific hearing requirements. This customization prevents listening at excessively loud volumes, which could damage hearing, and ensures optimal sound quality tailored to the individual. The app also provides access to other features, including Bluetooth connectivity.

The Acuity offers three pre-set listening modes to adapt to different environments:

• General (standard mode): Ideal for indoor use and quiet environments.
• Restaurant (noise canceling mode): Designed for louder environments, such as outdoor public areas and restaurants, to reduce background noise.
• Traffic (high-level noise canceling mode): Provides superior noise cancellation in very loud environments, like subways or windy conditions, to ensure clear hearing.

Users can easily switch between these modes by cycling through a mode button located on either side of the device. Once the app is set up, the hearing test completed, and the user profile updated, these modes automatically adjust to the user's selections, providing the best possible sound quality at the right volume, configured to their personal requirements.

For connectivity, the Acuity uses Bluetooth to pair with smartphones. The pairing process involves turning on the device, pressing and holding the mode/pairing button until the LED indicator flashes blue and red, enabling Bluetooth on the mobile device, and then searching for and pairing with "Hear+Hi Acuity Stereo." A flashing purple LED indicates a successful Bluetooth connection with media playing.

Usage Features:

The Acuity is designed for comfortable and effective wear. It comes with two sets of eartips in mini, small, medium, and large sizes. Users are encouraged to try different eartip options, as the size of the ear canal may not be the best guide. Often, a smaller eartip fits better by going deeper, or a larger one might provide more comfort and better occlusion. Proper eartip insertion is crucial for optimal sound quality, minimizing required volume, preventing leakage, and avoiding feedback (a whistling sound). Eartips should be aimed forward and up to match the angle of the ear canal, and different angles and sizes should be tried to maximize comfort and seal. The eartips attach to the earphone nozzle by gently pulling to cover it, avoiding excessive pulling to prevent tearing.

The depth of earphone insertion also affects sound quality and seal, so users should experiment with different depths to optimize their listening experience. The device is designed to be worn around the neck and under the shirt collar to prevent rubbing against objects and reduce friction noise.

The device is powered on by sliding the power button to the "On" position. Volume settings are adjustable using +/- buttons located on either side at the outer base of the device. However, a caution is issued that listening at high volumes may damage hearing.

The Acuity has a long battery life, providing approximately 10 hours of continuous use when fully charged. Charging takes about 3 hours. The device should be recharged before going to sleep nightly, regardless of battery status, and should not be completely discharged before recharging, as this can reduce battery life. When plugged into a power source, a solid red LED indicates charging, and a solid blue LED indicates a fully charged battery. A compatible USB adapter is required for charging.

Maintenance Features:

Proper maintenance is essential for the longevity and performance of the Hear+Hi Acuity.

• Disassembly and Repair: It is strictly prohibited to disassemble, modify, or repair the headset. Any such actions could void the warranty and potentially damage the device.
• Cleaning: Users should clean their ears and the unit before each use to prevent clogging and ensure optimum quality. A cleaning brush or soft cloth should be used to clean all parts of the headset, including the charging ends. It is important to avoid using water, solvents, cleaning fluids, or cleaning oil, as these can damage the device.
• Dryness: The earphones should be kept dry and clean. Humidity, earwax, and water in the ear can negatively affect the service life and performance of the device.
• Charging Habits: The device should be recharged before going to sleep every night, regardless of its current battery status. If the headset is not in use for an extended period, it should be charged weekly to maintain battery health.
• Storage: The device should be stored in a dry, safe place, away from direct sunlight, and protected from excessive high and low temperatures.

Safety Guidelines:

• The product should not be used by anyone else without permission.
• Appropriate volume levels should always be used to avoid hearing damage.
• The device should be kept out of reach of infants and young children.
