It explains how to adjust the guitar strings until the correct note name appears on the display, with the central indicator lighting up when the string is in tune. Additionally, instructions are provided for replacing the two AA alkaline batteries required for the tuner and preamp, emphasizing the use of only alkaline batteries and replacing both simultaneously. This manual is written in Chinese.
The instrument requires two AA size alkaline batteries (LR6).
Battery life is approximately 180 hours when not using the tuner.
Removing the guitar audio line from the output jack turns off the preamp power.
