Troubleshooting
The unit does not turn on
• Are the batteries facing the correct way?
• Have you inserted the specified type of batteries, or are you using the specified AC adapter?
No sound
• The volume dial might have been set to minimum.
• Are there any devices plugged into the headphones/line out jack? If a device is connected to
these jacks, no sound is output from the internal speaker.
• The unit may malfunction if you’ve connected a device to the headphones/line out jack with a
four-conductor (TRRS) plug. Use a three-conductor (TRS) stereo plug instead.
Noise
• As the batteries run low, the volume may become insufficient, or the sound may distort.
Replace the batteries with new ones if this happens.
MODE button does not respond (cannot switch modes)
• When playing back or recording, press the button to stop, and then switch the mode.
Connected pedal switch does not respond
• The pedal switches may not work correctly if you are pressing the pedal switch while turning on
the unit. Try turning off the power and then turning it on again.
