For more on the note names in each tuning mode, refer to the Tuning Mode Note Name List. The note name or string number for the note closest to the tone being played appears in the display. The meter and Tuning Guide show how far the note is from the correct pitch. When the desired note name or string number appears in the display, tune the instrument so that both Tuning Guide indicators are lit and the pitch matches that displayed by the meter. When you reach a stable pitch, the meter's lights then stream to the center from the left and right, indicating that tuning is completed (Accu-Pitch sign function). Connecting an FS-5U allows you to switch the tuner on and off away from the tuner. However, you can set the tuner so that the signal is output regardless of whether the tuner is on or off. The signal output from the OUTPUT jack passes through a buffer amp, and is converted to a low-impedance signal that is highly resistant to external noise. Depending on the circumstances of a particular setup, you may experience a discomforting sensation, or perceive that the surface feels gritty 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 (see figure) 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.
