• The START/STOP switch located on the top panel blinks in two colors - red and green - for an unmistakable visual indication of the tempo. It's a great feature if you want to practice with a silent metronome.
• From basic beats to variations like son clave and rumba clave, the KDM-2 contains a total of 19 beat patterns.
  You can set the tempo in any of three ways. Full Step mode that lets you adjust the tempo over a range of 30 through 252 in steps of one. Pendulum Step mode lets you set the tempo using the preset tempo settings, as on a mechanical metronome. And Tap Tempo lets you set the tempo by pressing the TAP switch at the desired interval.
• Sound Out mode outputs a reference tone that you can use as a tuning guide. You can listen to any of the twelve pitches from C4~B4. You can also adjust the A4 frequency (calibration) in a broad range from 410 Hz to 480 Hz.
• The KDM-2 provides a memory backup function that remembers the specified tempo, beat, calibration, and reference pitch even when the power is turned off.
• The KDM-2 is designed for long battery life. It will continue marking an accurate tempo for approximately 120 hours of continuous use at a tempo of 120 beats per minute.

This is a gently used metronome in excellent working condition. It was stored in a padded case when not in use. From a smoke and pet free environment.
