Timer Operation
Quick Start – Setup
Plug the power supply into the rear panel. Use the DSan Power Supply Model WP (110-220 V AC) which
can provide 12 volts at up to 1 amp — enough to drive the timer and two connected signal lights. (For
additional signal lights, use a larger power supply or a power booster hub. The signal lights may also be
powered locally. See Accessories, Page 8.)
Push the power switch (A) to turn on.
Set Total Time – Use the Up-Down arrow buttons below the Total Time display (B). Each button-press
increments or decrements one minute. To set seconds, press the "Set Seconds" button. The displays
will blink. While blinking, each button-press increments or decrements one second.
Set Sum-up Time – Use the Up-Down arrow buttons
below the Sum-Up display (C). Sum-Up time represents
the amount of time remaining when the yellow phase
light (E) is illuminated. Note: Sum-Up Time cannot be
greater than Total Time.
Press Start (D) – The time displays turn bright red, the phase lights (E) illuminate, and the Time
Remaining display (F) begins counting. Note: Counting is, by default, in the down direction and by
MINUTES:SECONDS. This can be changed to the counting up direction and/or by HOURS:MINUTES using dip
switches. (See Dip Switch Settings page 5.)
Programs
Programs are useful for debates or contests where pre-set timing formats must be selected quickly or
where timekeeping is separate for each speaker.
To pre-set a program, select that program.
Set Total Time, Sum-up Time, Blink, and Beep.
These settings are saved for the selected program.
Programs 1, 2, and 3 cannot run simultaneously with
each other. Toggling between these programs stops the
clock if it is running. Program 4 (Session) can run
simultaneously in background while Program 1, 2 or 3 is running and is selected for display.
A dimly lit Program LED indicates that a program is running in background. A brightly lit LED indicates
that the program is selected for display. A signal light set to display all programs will display the
program that is selected on the timer. Signal lights can be set to display any or all programs using the
signal light dip switches 1-4.
Press Clear to return the settings of a selected program to 0:00. Press Repeat to reset Time Remaining
to Total Time.
