The width of the binoculars does not suit the width between your eyes. The diopter has not been properly set. The binoculars are not properly focused. There are no batteries loaded. When the Image Stabilizer button is pressed, the lamp does not light. The battery power is low. The batteries are exhausted. Corrective Measures Use a blower brush to remove dust, etc., from the lens surface. Then use a soft, dry cloth to wipe the lens gently. Adjust the width of the binoculars (see step 4). Adjust the diopter (see step 5). Focus the binoculars (see step 6). Load batteries having enough power. If the lamp does not light, it means the batteries are exhausted.
