Setting the Time
Time is set on the DDC Series Wall Clocks by depressing buttons located on the left side of the front panel.
There are two setting buttons, "H" for hour and "M' for minute.
» To advance the hour or minute to the correct time one digit at a time press and release the proper
button. Do this as many times as required until the correct time is displayed. When setting the
hour, if the display is set to 12 Hour, a "dot" in the upper left corner of the display represents the
PM hours.
» To rapidly advance the hour or minute press and hold the proper button. Release the button when
the correct time is displayed. When setting the hour, if the display is set to 12 Hour, a "dot" in the
upper left corner of the display represents the PM hours.
Note: Setting the minutes past 59 will not cause the hour to advance.
Note: Avoid using sharp or pointed objects to set the time as damage to the buttons may occur. A standard
pencil eraser is suggested.
