7. Otkrivanje problema
Ako naiđete na probleme, razmotrite sljedeće uobičajene korake za rješavanje problema:
- Nema napajanja: Check the power cable connection and the power outlet. Ensure the power switch is ON.
- Nema zvuka: Verify all cable connections (instrument, speaker, footswitch). Check the MASTER volume and ensure the MUTE function is not active on the amplifier or footswitch. Confirm your instrument is working correctly.
- Izobličen zvuk (nenamjerno): Check input gain levels and ensure they are not excessively high. Adjust VOŽI i NIVO kontrole.
- Nožni prekidač ne reaguje: Ensure the footswitch cable is securely connected.
- pregrijavanje: Osigurajte amplifier has adequate ventilation. If the amplifier shuts down due to overheating, allow it to cool down before restarting.
Ako problemi potraju, obratite se kvalificiranom tehničaru.
