Many Roland and BOSS products can be powered by batteries - such as the BOSS compact and twin pedals. If you find that your product won't power on, is malfunctioning, or the sound quality is inconsistent while using battery power, check the following:
- Replace the battery/batteries with those you are certain are new, and confirm they are inserted/ installed correctly.
- Confirm that you are using the correct type of batteries that are recommended within the Owner's Manual.
- For most compact and twin pedals, the 1/4" INPUT or OUTPUT jacks act as the power switch and the pedal will not power on unless a 1/4" mono (unbalanced) instrument cable is connected. Confirm in the Owner's Manual as to whether the INPUT or OUTPUT is used for the power switch.
