Tuning procedure

The POWER ON LED will light up, and the calibration setting (0–9) will flash in the note display
for a few seconds.
NOTE: If there is no user input for up to 4 hours, the auto power-off function will automatically
put the tuner in the standby power mode. Holding down the MUTE button and pressing
the STANDBY/ON button while the tuner is turned on will disable the auto power-off
