NOTE
Use only the provided strap. The included strap is meant for exclusive use with the MICRO CUBE GX.Do not use this strap for other products.
- Do not spin or swing the MICRO CUBE GX while holding it by the strap. This is extremely dangerous, as it may cause the strap to become detached; or, if the motion is repeated enough, may even break the strap.
Restoring the Factory Settings
If you want to initialize all the knob settings stored in memory, you can revert to the factory default settings as follows (Factory Reset).
1. While holding down the [MEMORY] button, turn on the power.
All indicators will blink, and the settings stored in memory will return to their factory-set state.
NOTE
When you execute the factory reset procedure, all knob settings that you've stored in the MICRO CUBE GX will be lost.
Ground terminal
Depending on the circumstances of a particular setup, you may experience a discomforting sensation, or perceive that the surface feels brittle to the touch when you touch this device, microphones connected to it, or the metal portions of other objects, such as guitars. This is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are concerned about this, connect the ground terminal with an external ground. When the unit is grounded, a slight hum may occur, depending on the particulars of your installation. If you are unsure of the connection method, contact the nearest Roland Service Center, or an authorized Roland distributor, as listed on the "Information" page.
Unsuitable places for connection
Water pipes (may result in shock or electrocution)
Gas pipes (may result in fire or explosion)
- Telephone-line ground or lightning rod (may be dangerous in the event of lightning)
