Tuning procedure
The GT-12 has two tuning modes: Meter mode (auto/manual) in which
you tune while watching a meter, and Sound mode (manual) in which
you tune to an audible reference tone.
Meter mode
1. 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 perfor-
mance 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.
