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.
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.

GLOSSARY
ALTERNATE TIME CONTROL SWITCHES (keys): Located on the keypad, these 2 keys, TIME ON
and TIME OFF, may be used instead of the Hand Held Time Control Switch.
NOTE: These 2 keys are inactive while the Hand Held Time Control Switch is plugged in. To enable them,
turn the control off, unplug the Hand Held Switch and restart the control. You may use “Start Where Left off
Last” if you wish.
AUTO HORN: Sounds for a minimum of 2 seconds when the main time has expired or reached the stop time.
(Can be disabled from the control)
AUX TIMER: An auxiliary timer, separate from the main timer, that can be configured to count up or down and to start and
stop with the time control switch or run continuously. It can be viewed on the control (press the time key twice) or on
an AUXILIARY TIME DISPLAY . Some uses for the aux timer include timing field or facility usage, or determining
how far into a game a certain event happened.
AUXILIARY TIME DISPLAY: Consisting only of a timer, it can display the main time, the AUX TIME or
the Chronometer (Time of Day Clock). Auxiliary Time Display models include: 9410, 9510, 9405 and 9505.
BATTERY: Battery powered memory saves the settings and data in the control in case of power failure. It also
maintains the accuracy of the CHRONOMETER when the control is unplugged.
BEEPER: Confirms each key press and alerts operator when a special event such as time expired or an Entry Error
has occurred.
BOOKMARK: Saves the current control settings and data so it can be easily recalled later. (5 Bookmarks are
available)
BRIGHTNESS LEVEL: The scoreboard can be set to bright or dim for best viewing. Indoor scoreboards
default to bright; outdoor scoreboards default to dim.
CHRONOMETER: Time of Day Clock. Once the correct time has been set, the accuracy of the Chronometer is
maintained even while the control power is unplugged. During normal operation, the Chronometer can be
displayed on the control by pressing a single key. This key can be armed so that when pressed, the Time of
Day is also displayed on the scoreboard.
NOTE: Pressing the TIME key or turning the time on will return the main time to the display(s).
DISPLAY: A 16 character display on the control prompts the operator for input and can monitor the scoreboard
data.
ENTRY ERROR: A visual and audible warning that an invalid action was attempted. Its normal duration is 2
seconds however you may interrupt it and continue immediately.

12
HAND HELD TIME CONTROL SWITCH: A hand held switch with a coiled cord that plugs into either
side of the control. When connected, the alternate time control switches (keys) are disabled. (Makes it easier
for another person to control the main time or sound the horn).
INTERVAL HORN: A horn that sounds repeatedly at preset intervals throughout the game. Its primary use is to signal
when little league hockey teams should rotate to the court. The Interval Horn has been replaced by a more versatile
SEGMENT TIMER. (See Segment Timer)
MODEL CODE: A 3 character code found on the OVERLAY that when entered into the control, sets up he
control for a particular scoreboard model and sport or special function.
OPTIONS: Settings that determine how the scoreboard system operates.
OVERLAY: A flat plastic panel that fits over and around the keys on the control. Tabs at the top and bottom hold it in
place. Each overlay provides the proper labeling for each key and a three character Model Code. A brief set of
operating instructions is printed on the back of each overlay; you may make copies if you desire. When you want to
change to a different sport, install the correct overlay and enter the new Model Code.
SEGMENT TIMER: Sometimes called Practice Timer, it allows a list of time segments to be programmed into
the control. The list can then be used for a practice routine or drill. When started, the first segment on the list
is loaded into the main timer and starts counting down. When zero is reached, the horn sounds and the next
segment is loaded and begins counting down with no intervention needed.
NOTE: The Segment Timer has replaced the Interval Horn and can mimic it exactly.
SUB HORN: When armed, waits until the main time has been stopped, then sounds automatically to alert the
officials that a player is waiting to be substituted into the game.
TENTH SECOND SHIFT TIMER: Automatically shifts from displaying minutes and seconds to seconds
and tenths of seconds during the last minute of count down time. (May be disabled if desired)
TIME OUT TIMER: Programmable for different time out lengths and with optional warning horn and an option
to display the Time Out time remaining on the scoreboard. (Ten different time out timers are available. Timer
0 is preset to 30 seconds with a warning horn at 10 seconds and is not displayed on scoreboard. )

Appendix ( Chronometer )
(Time of Day)
A CHRONOMETER (Time of Day Clock) is built into the control . Once set, it will maintain its accuracy even
while the control is turned off or disconnected from power. During normal operation the Time of Day can be recalled to the
display on the control by pressing a single key, the Chronometer key. The Chronometer key can be enabled so that when
pressed, the Time of Day will also be displayed on the scoreboard(s).
NOTE: Pressing the TIME key or turning the time on will return to displaying the Main Time.
Pressing Set, then Chronometer will initiate the set up mode. While in this mode, you can:
1. Specify whether or not the Time of Day will be displayed on the Auxiliary Time Display, if one is connected.
2. Enable or disable the Chronometer key so that pressing it will display the chronometer on the scoreboard. (the
default is to display the Time of Day on the control only)
3. Set the Time of Day Clock.
4. Allow the control to be turned off, disconnected, and stored away in a safe location, while the scoreboard or
auxiliary time display, or both, continues to display a running “time of day” clock.
NOTE: Some scoreboard models do not support all settings or options.
Questions that the control may ask include:
DO YOU HAVE AN AUXILIARY TIME DISPLAY CONNECTED?
(NOTE: Auxiliary Time Display models include: 9410, 9510, 9405 and 9505).
