• places where the unit will be in direct sunlight;
• 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.
N For maximum battery life, always be sure the tuner is turned OFF when not in
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.
N Never use solvents such as benzene or thinner to clean the tuner. Wipe clean
with a soft, dry cloth.

Never dispose of used batteries by burning them.
Also make sure to keep batteries away from children.

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.)

INPUT jack o.
2. Turn the POWER switch u ON.
