T://BCBD 2000 Programming Instructions
The Bogen BCBD 2000–Series digital clock is a four digit display, each digit made of
seven bars. There are two buttons on the right side of the display for programming.
The top button, when pressed alone, sets the hours (the first two digits). The bottom but-
ton, when pressed alone, sets the minutes (the last two digits). When setting the hours and
minutes, the display will scroll through the numbers at a rate of 1 per second. If the set
hour or set minute button is depressed for a length of time, the numbers will scroll faster.
When both buttons are pressed together, the clock enters programming mode.
After pressing the two buttons together and beginning program mode, the top button
moves the display through the different options (setting the date, enabling daylight savings
time, etc.). The bottom button allows for adjustment within each option (Month 1-12,
12/24 hour display mode, etc.)
The digital clocks have the capability of working as a slave, a master clock or independ-
ently. When using the digital clock as a master or independent clock, the colon (located
between the HH:MM) will flash. When using the digital clock as a slave, the colon will
flash only when the clock has lost input from the master. If the slave clock loses input,
that clock will flash its colon to signal this loss of communication and will work as a mas-
ter clock for the remainder of the system.
