Please read the below content carefully. ----------------------------------------------------------------------------------------------- 1. This item has a digital circuit with 4 channels and 2 programs. You could switch the programs by long-press the button with around 3 seconds per time, or adjust the volume by short-press the button within 1 second per time. 2. Before you put on the Jungle Care's hearing amplifier, please make sure that the VC wheel is not at the highest level. 3. You will find 6 differentt domes packed in the box. If you are not sure which size is most suitable for your ear canal, choose the medium one and try one by one. 4. When you put on Jungle Care's hearing amplifier for the first time, feel the sound, then take it off and use the screwdriver to adjust the volume until you can hear clearly and comfortablely. 5. IMPORTANT: If you hear the whistle, take off your hearing amplifier and try Step 4 once again. If you can still hear the whistle, replace the dome with a larger one. 6. If you feel uncomfortable due to the occlusion effect, replace the dome with a smaller one. The occlusion effect might happen within the low frequency range (below 400Hz). 7. We do not recommend you the Rayovac's battery. They have just updated their version to make the battery thicker, which may break the battery door. ------------------------------------------------------------
