Use of the device may aggravate the condition or delay healing. •Known or suspected skull defects or abnormalities in bone structure (e.g., after cranial surgery or with congenital bone conditions). Consult with a medical professional before use. •Persistent or unexplained dizziness, vertigo, or balance disorders. The vibrations of bone conduction may worsen these symptoms. •Severe mixed or profound sensorineural hearing loss. Bone conduction hearing amplifier is generally not effective for these conditions. •Allergic reaction to materials in the device or headband (e.g., silicone, plastic, or metal components). •Children under 18 years old unless directed by a healthcare provider. Young children may be more sensitive to vibration or improper fit. •Implanted medical devices such as pacemakers or neurostimulators. While bone conduction amplifier typically do not interfere, consult your physician to rule out potential interference. Read Before Use •Exposure to high temperature, high humidity, strong magnetic fields (>0.1T/MRI), X-rays, and mechanical stress can damage the hearing amplifier. •Do not place the hearing amplifier in an environment with high temperature or high humidity. Do not use the hearing amplifier while bathing, washing your face, shaving or putting on makeup. Do not place the hearing amplifier in a microwave oven. •Do not press the hearing amplifier buttons too hard to avoid damage. •Do not dispose of used hearing amplifier improperly. If you need to dispose of them, please follow the relevant national regulations. Safety Instructions - 2 - - 3 - Box Contents 1. Hearing Amplifier2.

Introductions Charging Instructions Battery level: >75% Battery level: 50%~75% Battery level: 25%~50% Battery level: 15%~25% Battery is low. Checking Battery Level When the hearing amplifier is powered on, click the power button once to illuminate the battery indicator and get to know the current battery level: Charging the Hearing Aids When the hearing amplifier battery level drops below 20%, the battery indicator lights will flash and the speaker will issue a voice prompt to alert you. 1. Connect the hearing amplifier to a USB-C power source (power adapter is not included). 2. Charging Indicator Lights • Flashing: Charging in progress • Stay Solid: Fully charged. 3. Charging Time: It typically takes 1.5 hours to fully charge the hearing ampilifier. Position the Device on Your Head: Place the transducer pad just in front of your ear, on the cheekbone or temporal bone. Ensure the pad sits firmly against the bone, not on soft tissue or the ear canal. Wear Glasses with Care (if applicable): If you wear glasses, put the hearing amplifier on after your glasses to prevent interference with placement. - 6 - Introductions How to Wear the Hearing Amplifier - 7 - Power ON •Hold the power button for 3 seoncds as the battery indicator flashes. Power OFF •Hold the power button for 3 seoncds. Volume Adjustment The left and right hearing amplifier volume can be adjusted separately, each supports 5 volume levels. •Slide the volume switch to the side that the volume needs to be adjusted. •Press the volume buttons to increase or decrease the volume, you will hear Maximum Volume voice prompt when it reaches to max volume, and Minimum Volume voice prompt when it reaches minimum volume. Hearing Mode Switch Slide the hearing mode button to set it to indoor mode, outdoor mode and conversation mode. •Indoor Mode: Optimized for quiet environments like home, offices, or libraries. Enhances speech clarity while reducing low-level background noise. •Outdoor Mode: Desi…
