[. . . ] A7 Clarinet / Clarinette Klarinette / Clarinete A8 Bassoon / Basson Fagott / Fagot THE FCC REGULATION WARNING (for USA) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. [. . . ] Auto: The backlight will light brightly when sound is input or when a button is operated. When there has been no input or button operation for approximately ten seconds, the backlight will change to the "Soft" level of brightness. (Refer to "Recommended locations for attachment") The setting will alternate between MIC and PIEZO each time you press the button. If you want to change the reference pitch (calibration), press the CALIB [ ] or [ ] button. The display will show the name of the note closest to the pitch detected. Tune your instrument to the correct pitch so that the desired note name appears. Once again play a single note on your instrument, and adjust the tuning so that the center segment of the meter is lit. The right (+) indicator will light if the pitch is too high, and the left (-) indicator will light if the pitch is too low. You have the option of reversing the direction of the AW-2’s meter between left and right, but in our explanation here we will assume that the High (+) indicator is located at the right side.

The battery included with the AW-2 is for the purpose of verifying that the unit operates correctly, and may not have a very long life. When the battery begins to run low, the liquid crystal display (in particular the meter movement) will become fainter and the backlight will become dimmer. The AW-2 will continue to operate for a while longer, but tuning will become less accurate. With the ball of your thumb, lightly press the battery cover located on the back of the AW-2, turn it counter-clockwise, and remove it. [. . . ] You can also switch the input to the internal mic (MIC) and attach the tuner to a music stand rather than to your instrument. If you've selected the internal mic, you can also use the tuner without the clip. Leaving the AW-2 attached for a long time may hurt the instrument surface. [. . . ]
