Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| El dispositivo no se enciende. | Battery is depleted; "HOLD" switch is engaged. | Charge the battery; ensure the "HOLD" switch is in the "OFF" position. |

| No hay sonido o la calidad del sonido es mala. | Headphones not connected properly; volume too low; faulty headphones/AUX cable; incorrect FM frequency. | Ensure headphones are fully plugged into the 3.5mm jack (13); increase volume; try different headphones/AUX cable; verify FM frequency matches car radio. |
| El CD salta con frecuencia. | Disc is dirty or scratched; severe vibration. | Clean or replace the disc; ensure the player is on a stable surface or minimize movement during use. The anti-skip feature helps but extreme conditions can still cause skips. |

For digital scanning radios, manual tuning might be required if available, or use the AUX cable if your car has an AUX input. |
