Storefront Demo Display Turn off the power (unplug the instrument from the INPUT jack). Hold down [FLAT TUNING] and turn on the power (plug the instrument into the INPUT jack).

FLAT TUNING Button: Sets the amount the pitch is lowered in flat tunings. FLAT TUNING Indicator: Indicates the flat tuning setting. MODE Indicator: Indicates the tuning mode setting. TUNER ON/OFF Switch: Switches the tuner on and off. TUNER ON/OFF Indicator: Lights when the tuner is on. PITCH Button: Displays the reference pitch. Set the FS-5U's polarity switch to the jack side. Connect an effects processor, guitar amp, or other such device here. Normally, the output is muted while the tuner is on. 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. 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) You can use the 7-pin parallel DC cable to supply power to effects processors and other PSA adaptor-compatible gear. [. . . ] The movement of the light slows down as the note approaches the correct pitch, then stops when you reach the correct pitch. · · · Convenient Functions Using the Meter Display to Indicate Tuning is Completed (Accu-Pitch Sign Function) The TU-12 features an Accu-Pitch sign function that uses the meter display to indicate that tuning is complete after the pitch stabilizes at the correct pitch. When tuning is completed, the lights stream toward the center from the left and right. 17. DC OUT Jack * * Plug 1. 3. AC Outlet Switching the Accu-Pitch Sign Function On and Off 1.
