Setup and Fitting
- Choose the Right Ear Dome: Select an ear dome size that fits comfortably and securely in your ear canal. A proper fit is crucial to prevent sound leakage and feedback (whistling).
- Attach the Ear Tube and Dome: Securely attach the clear ear tube to the hearing amplifier's sound outlet. Then, firmly attach the chosen ear dome to the end of the ear tube.
- Adjust the Ear Tube Length: If the ear tube is too long or too short, it may cause discomfort or an improper fit. If necessary, carefully trim the ear tube to ensure the amplifier rests comfortably behind your ear while the dome sits securely in your ear canal.
- Place the Amplifier: Gently position the amplifier behind your ear. Guide the ear tube over the top of your ear and carefully insert the ear dome into your ear canal until it feels snug and comfortable.

- Power On/Off: Locate the switch button (typically labeled "ON/OFF") on the device. Slide it to the "ON" position to activate the hearing amplifier. To turn off the device, slide the switch to the "OFF" position.
- Adjust Volume: Use the designated volume buttons, which may be a wheel or a rocker switch, to increase or decrease the sound level. Adjust the volume gradually to a comfortable listening level. Higher numbers usually correspond to louder sound.
- Change Modes: Short press the mode adjustment button to cycle through the available listening modes. Each press will switch to the next mode, indicated by a distinct sound cue:
- One "di" sound: This mode is suitable for most general hearing environments.
- Two "di di" sounds: This mode is optimized for outdoor environments.
- Three "di di di" sounds: This mode is designed for noisy environments to enhance speech clarity.
