Congratulations on your timer purchase! Your new timer should
provide years of trouble-free service. To maximize the performance
and life of your timer, please read this user's manually carefully
before using your timer. It is important to familiarize yourself with
the timer before attempting to use it at your first event.
INTRODUCTION
Your new timer comes in a protective carrying case. Inside
the case you'll find the following items:
• Timer Console ("MD-300 Electronic Timer")
• Infrared light source ("Transmitter")
• Infrared light detector ("Receiver")
• Camera tripods (2)
• 125 foot cable
• A/C power adapters (2)
The MD-300 Timer supports a wide variety of events. The
basic timer with the equipment listed above can support
speed events such as barrel racing and pole bending. It can
also be used to time show jumping events which use a sin-
gle entry and exit point. With optional equipment, the MD-
300 Timer can support additional events including team
penning, cutting, calf and team roping, dash / sprint events
and more!
This manual provides instruction for operation of the MD-
300 Electronic Timer. Topics include operation of the Timer
Console, use of the electric eyes and using the setup capa-
bility of the timer to select the type of event to be timed. For
events which require the use of optional equipment, addi-
tional information is provided in the user's manual supplied
with the optional equipment.
THE TIMER CONSOLE
The Timer Console is the heart of your new timer system.
The front of the Timer Console has four push-buttons for
controlling the timer and a time display. The back of the
Timer Console has five jacks for connecting power, the light
detector, an optional horn, an optional scoreboard display
and other accessories. These connections are discussed in
detail in later sections.
The best way to learn about your new timer is to use it. Try
each of the operations outlined in the following sections as
you read through the manual.
Turning on the Timer Console
The Timer Console must be plugged into a standard wall
outlet to operate. Using either of the A/C power adapters
provided (they're identical), insert the small plug into the
POWER
jack on the rear of the Timer Console and plug the
adapter into a wall outlet. As soon as the Timer Console is
plugged in, the Console is "on" and the time shown on the
display is zero. Now we're ready to push some buttons!
Manually Starting and Stopping the Timer
The
START/STOP
button is used to manually start and stop
the timer. When the timer is started, the time is first reset to
zero, and then the running time is shown on the display.
When the timer is stopped, the final time is shown on the
display.
When the Timer Console is not running, pressing the
START/STOP
button starts the timer. If the timer is running,
pressing the button stops the timer. Even if the timer was
started by breaking the light beam, it can be stopped with
the
START/STOP
button, and vice-versa.
Resuming an Interrupted Timing
Whenever the timer is stopped via the
START/STOP
button or
by breaking the light beam, the final time is shown on the
display. However, the timer continues to count "inside."
Pressing the
RESTART
button, when the timer is stopped, re-
sumes timing on the display. Since time was kept internally
while the display was "frozen," the time on the display now
reads as if the timer was never stopped. (Note: When using
the timer for jumping events, operation of the
RESTART
button is slightly different than described here. See the
jumping event entries in the "Event Summary" table later in
this manual).
