TROUBLESHOOTING
When your unit seems not to work properly, take a few minutes to troubleshoot before calling service. You can save yourself
time and money by doing it yourself, because the source of problem is often something quite simple.
What is the problem?
1. There is no sound from the amp and LEDs don t light up. -> Check your AC outlet
1.1. Outlet is ok. -> Check power cord, unit fuses (BC150 only, BC20, BC40 and BC80 has no user serviceable fuses)
and power switch.
1.2. No power in outlet. -> Check house fuse box.
2. There is no sound from the amp with LEDs Lit. -> Check amp gain and/or volume controls, check guitar controls. If
controls are ok and all set above zero then listen for hum in the speaker.
2.1. There is no hum in the speaker. -> Internal speaker or power amp may need serviced.
2.2. There is small hum in the speaker. -> Unplug guitar, touch tip of cable and listen.
2.2.1. Hum is now very loud. -> Check your guitar electronics or try different guitar.
2.2.2. Hum does not change. -> Replace your guitar cable.
3. Sound quality is poor. -> Replace your guitar cable. If this does not help then check your speaker and speaker cable.
If the problem is not covered by the above or if our solutions does not help then please contact Warwick service
