To release a conductor, grip the conductor with your free hand, while holding the device with the chrome activation panel facing you and press firmly on the gray release button with your thumb until the conductor is released from the instrument. To attach a conductor, hold the instrument with the display side up and hold the conductor with the positioning indicator (small etch) facing you. Press firmly to snap the conductor into place. If your conductor fails to attach, make certain the conductor is positioned correctly. Forcing the conductor could damage both the instrument and the conductor. The instrument will not work unless the conductor is attached correctly.
