There are many new clocks today which have the appearance of old wall clocks or grandfather clocks, complete with pendulums and weights, but in fact the new clocks use quartz movement. Quartz clocks have become the most widely used timekeeping devices over the last forty years. Quartz crystals vibrate and oscillate at a specific frequency when powered. This oscillation is very precise and can be used to measure time.
Insert the batteries.
Use the time setting knob to adjust the time. Alternately, set the time using the clock's minute hand. Rotate the hand clockwise. Do not rotate the hour hand---it will move in sync with the minute hand. Set the correct time.
Set the chime melody. Many clocks allow you to choose between Westminster and other sounds. The switch will probably be marked "Off," which represents silence, "West" for Westminster, and "Melody 2," which can be any other melody, depending on the clock.
Set the volume control knob to modify the chime.
Set the nighttime silence feature. There are usually three settings. The icon with a diagonal stripe sets the clock for silence for eight hours following the time you threw the switch. This cycle repeats every twenty-four hours. The icon with a musical note reduces the volume for eight hours, and the icon with a speaker symbol is for full chime volume.
Set the 4/4 chime melody feature. The "4" position plays 1/4 of the melody at quarter past the hour, 1/2 the melody at half past the hour, 3/4 of the melody at three-quarters past the hour, and the full melody on the hour. The "1" position plays the full melody at the top of the hour only.
