Troubleshooting
General
Restore factory settings: In order to revert the Gemini to its factory settings, clearing all user data,
presets, expression mappings and custom effect types, perform a factory reset using one of the
methods described below.
Factory Reset using the Neuro App
Using the Neuro App, go to Hardware Settings and choose the Factory Reset option.
Factory Reset using the Hardware (Firmware v1.06 and later)
Disconnect power. While holding down the footswitch, reconnect power. The main LED and control
LED will be lit for a few seconds. When the reset is complete both LEDs will turn off and you can
release the footswitch.
Noise
Power source: Ensure that the proper power supply is being used.
Near noise source: Move pedal away from power supplies and other equipment.
Other equipment: Remove other effects from signal chain; see if noise persists.
Bad cables: Swap out audio cables.
USB ground loop: When connected to a computer using a USB cable, noise can appear in the audio
signal. This usually results from ground loop noise due to the Gemini and computer running on
separate power supplies. In the case of laptops, the noise can often be mitigated by disconnecting
the computer’s power supply and running it on a battery. External display monitors are often the
primary source of noise, and powering down monitors can also resolve noise issues.
Hot Hand Doesn’t Work
Low power: Ensure that the proper power supply is being used.
