If you are using an instrument with a pickup (such as an electric guitar) or a mic, connect the instrument or mic to the INPUT jack of the GT-12. (If you connect the GT-12's OUTPUT jack to your amp etc., the sound will be output thru the tuner. During your performance however, you may want to turn the GT-12 power switch OFF to avoid noise.) If a plug is inserted into the INPUT jack or OUTPUT jack, the built-in mic cannot be used. Both jacks are mono. They cannot be used with stereo plugs. If you wish to tune your instrument using the built-in mic, do not connect a plug to the INPUT jack or OUTPUT jack. In steps 5 and 6, place your instrument as close as possible to the built-in mic. 2. Turn the power switch to the ON or position. (At the position, the power will be on, and in addition the display will be illuminated.) When the power is turned on, the previously-selected reference pitch (default setting: A=440 Hz) will be selected, and the GT-12 will be in Meter mode (Auto) 3. If you wish to change the reference pitch (calibration), press the [CALIB] switch. Each time you press it, the reference pitch will rise 1 Hz. If you continue holding it, the pitch will rise continuously. The available range is 438 Hz­445 Hz. 4. Rotate the [TUNING TYPE] dial to select the appropriate instrument or set to CHROMATIC. Move the appropriate instrument name to the mark. Each setting allows the following tuning.
