Here’s how to return the DM-101 to its factory-set state.
- Press and hold down the [ON/OFF] switch and [TAP] switch, and turn on the power.
- Press the [TAP] switch.
This starts the factory reset. The MEMORY indicators light up in this order: MANUAL>>1>>2>>3>>4. The reset is finished once the [ON/OFF] switch lights up - Turn off the power.
Note: Don’t turn off the power while the factory reset is in progress.
