| Directions | 1. If you hear 'zhi ~ zhi' noise in your headphones while using B4-X with your cellphone, keep your cellphone far away from B4-X to avoid interference from WIFI or 4G signals. 2. If the right channel has static, it might be due to a poor contact of the tube after long shipping. Open the chassis and adjust the screw near the tube while listening. If the tube is broken, buy a 5899 tube in local shops and we will refund you the cost. 3. If it breaks with four loud pops and doesn't work, charge the battery as it might be run out of power. 4. Keep the amp away from devices that can transfer signals like cellphones and routers to avoid electronic feedback/interference. 5. If the charger is broken, contact us to get a new one. |
