The Cherub WST-645 comes with a built-in rechargeable Li-ion battery. Before first use, it is recommended to fully charge the tuner.

• Sæt den anden ende af kablet i en standard USB-strømadapter (medfølger ikke) eller en computers USB-port.
• The battery indicator on the display will show charging status. A full charge typically takes a short amount of time (around 15 minutes for a half-depleted battery, as per user reviews).

5.2 Selecting Tuning Modes

The WST-645 supports 5 tuning modes: Chromatic, Guitar (Standard), Guitar (Compensated), Bass, and Ukulele. The tuner is designed to automatically detect the instrument type and switch to the appropriate mode. If manual selection is needed, refer to the small button on the side of the tuner (if present, not explicitly mentioned in data, but common for tuners) to cycle through modes.

The "Guitar (Compensated)" mode is specifically designed for improved intonation on guitars, adjusting for slight pitch discrepancies across the fretboard. Refer to the table below for compensated tuning values:

5.3 Stemning af dit instrument

Once the tuner is attached and powered on, pluck a single string on your instrument. The tuner will detect the note and display it on the screen. The large color LCD provides clear visual feedback:

• Flad: If the pitch is flat, the left side of the display will illuminate in blue, and the needle will point to the left. Adjust your string upwards until the display indicates "in tune".
• I harmoni: When the note is in tune, the center of the display will illuminate green, and the needle will be centered.
• Skarp: If the pitch is sharp, the right side of the display will illuminate in red, and the needle will point to the right. Adjust your string downwards until the display indicates "in tune".
