• places subject to temperature and humidity extremes;
• places that are sandy or dusty.
N To power the tuner, use only a 6F22 or 006P 9V dry cell battery.

use.
N If an exhausted battery is left in the unit for an extended period of time, it may
leak and cause malfunctioning of the unit. When the battery becomes
exhausted, always remove it and replace it as soon as possible.
N Do not subject the tuner to strong physical shock or vibration. Do not use
excessive force on any of the controls.

The tuner will automatically select the closest note name (string name) to the
plucked string's pitch.
1. For electric guitars/basses, connect the guitar cable to the INPUT jack o.
(The OUTPUT jack i can also be connected to an amplifier. The guitar's
signal will be sent to the amp whether the tuner's power is switched ON or
OFF. However, it might result in added noise to the line so you should
switch the tuner's power OFF during performance.)
* The built-in microphone y will not operate when a cable is plugged into the
INPUT jack o.
2. Turn the POWER switch u ON.
The standard pitch (factory preset A=440Hz) will flash on LCD indicator q
