Switch the tuner ON. The two InTune LEDs will flash
once per second to show it is on and ready.
Play a single note, and adjust that note until the desired string indicator
is on. Slowly make the final adjustment until the two InTune LEDs are
on. The flat and sharp LEDs blink more slowly as you approach InTune.
Observe the "visual beat" as you are
tuning. It is best to tune up from flat up to InTune than from sharp down.
It is not necessary to repluck the string often, every few seconds is
fine.
When InTune mute all strings with the right hand before going to the next
string. For the fastest tuning, tune at the twelfth fret harmonic.
