*NOTE: This question is asked only once for each time the control is started fresh by entering a model code. It may
be asked from SET OPTIONS or from SET CHRONOMETER. The control needs to know this information in order
to know what other questions to ask and how certain data should be handled.
** Questions will be asked only if you indicated that you have an Auxiliary Time Display connected.

12
The Set Options Menu
DO YOU HAVE AN AUXILIARY TIME DISPLAY CONNECTED?
The control will need to know if an auxiliary time display is connected as part of your system. The Auxiliary Time Display is
used to display time (Main Time, Auxiliary Time or Time of Day). Auxiliary Time Display models include: 9410, 9510,
9405 and 9505.
NOTE: This question is asked only once for each time the control is started fresh by entering a model code. It may be ask
from SET OPTIONS or from SET CHRONOMETER. The control needs to know this in order to know what other questions
to ask and how certain data should be handled.
DO YOU WANT TO SWITCH TO DIM?
OR
DO YOU WANT TO SWITCH TO BRIGHT?
Answering YES will toggle the brightness level of the scoreboard.
USE AUX TIMER?
OR
SET AUX TIMER?
OR
TURN AUX TIMER OFF?
The control has a built in auxiliary timer that can be used for many purposes. It can be configured to count up or down and it
can run continuously or only when the main time is running. It can be displayed on the control by pressing the time key twice
in succession. It can also be configured to display on an auxiliary time display if one is part of your system. Some uses for the
auxiliary timer include timing field or facility usage, or it can be used to determining how far into a game a certain event
happened.
AUX TIMER TO COUNT DOWN?
Answering YES will setup the timer to count down (99 hours: 59 minutes: 59 seconds maximum).
NOTE: The auxiliary time display will show hours and minutes until the remaining time drops below an
hour, then it will show minutes and seconds.
Answering NO will setup the timer to count up (59 minutes: 59 seconds maximum).
START AND STOP WITH TIME CONTROL SWITCH?
Answering YES will setup the timer to start and stop with the action of the same switch that controls the main time.
Answering NO will setup the timer to run continuously regardless of the switch position.
DISPLAY AUX TIME ON AUXILIARY TIME DISPLAY?
Answering YES will cause the aux time to be displayed on the auxiliary time display.
Answering NO will cause the auxiliary time display to continue displaying the main time or the time of day.
DISPLAY CHRONOMETER TIME ON AUXILIARY TIME DISPLAY?
Answering YES will cause the time of day to be displayed on the auxiliary time display.
Answering NO will allow the auxiliary time display to continue without change.

13
ENABLE SEGMENT TIMER?
A segment timer is a separate internal timer that automatically resets itself to the next time in a pre-determined list. When the
time counts down to zero, the horn sounds and the next segment of time in the list is loaded and it continues to run. When the
end of the list is reached, it starts over with the first segment and continues indefinitely. It is primarily used for practice drills.
An Interval Horn is a horn that sounds every time the main time is evenly divisible by the interval time. Its primary use is to
signal when little league hockey teams should rotate to the court.
The Segment Timer can be set up for practice drills or to work like an interval horn.
For interval horn, enable the timer, set only the first segment, and do NOT display the segment timer on the
scoreboard. During normal game play, a horn will sound each time the length of the segment elapses.
Enabling the Segment Timer will allow entry of the time for segment 01. Enter the minutes and seconds as desired then press
YES.
ADD ANOTHER SEGMENT?
There can be as many as 40 segments in the segment list. When the end of the list is reached, the segment timer
starts over with segment 01.
or
DISABLE SEGMENT TIMER?
Disabling the segment timer clears all segments and returns to normal operation.
NOTE: If you will want to use this configuration again, be sure a bookmark has been saved before disabling.
NOTE: If the segment timer has been displayed on the scoreboard, to return to normal operation it is necessary to turn the
control power off and start fresh with a model code or from a bookmark.
or
EDIT SEGMENT TIMER?
The edit option allows you to review the segment list, shorten the list, extend the list, or change a segment’s time.
NOTE: For more help and examples see Appendix (Segment Timer)
DISPLAY SEGMENT TIMER ON SCOREBOARD?
If you answer YES, the segment time is displayed instead of the main time and is started and stopped with the time
control switches.
NOTE: To return to normal operation it will be necessary to turn the control power off and start fresh with a model
code or from a bookmark.
Answering NO will cause the segment timer to act like an interval horn.
STOP TIME AT EACH SEGMENT?
If you answer YES, the time will stop at each segment and wait for TIME ON.
NOTE: If you are using a hand held time control switch, turn the switch off, then on.
or
ALLOW TIME TO RUN AFTER EACH SEGMENT?
NOTE: For more help and examples see Appendix (Segment Timer)

14
CHANGE DIRECTION OF MAIN CLOCK?
Toggles the direction the main clock runs.
CLOCK TO STOP AT SPECIFIED TIME?
A stop time may be set when the timer direction is changed to up count. When the clock reaches the stop time, the
clock stops and the auto horn will sound if enabled.
If you answer YES, you are prompted for the stop time. Follow the prompts.
DISABLE .1 SEC. SHIFT TIMER?
During the last minute of count down time, the scoreboard switches to displaying the seconds and tenths of seconds.
Press YES if you want to turn off this feature.
NOTE: Once disabled the only way to restore it is to restart the control and enter the model code or go to a bookmark.
SET A BOOKMARK?
A bookmark is like a picture or snapshot of all the data and configuration settings in the control. When you go to a bookmark,
the control is restored to where it was at the time the bookmark was saved.
Bookmarks can be edited by going to the bookmark, making the changes needed, then saving the bookmark again using the
same bookmark number or a different one.
Five separate bookmarks are available and each can be reused as desired.
If you try to save to a used bookmark, you will be warned and given a chance to abort the procedure.
NOTE: A bookmark cannot be saved while a timer is running.
