Daktronics identifies manuals by the DD or ED number located on the cover page of each
manual. For example, this manual would be referred to as ED-12935.
1.2 Horn Start Overview
Every heat in swimming has a start. The rulebook states, “The starter should be on a separate
system that is designed specifically to provide clear and simultaneous instructions at each of
the starting platforms.” In addition to needing something to start each heat, many teams train
for starts during practice. A typical beginning of a race starts with the referee or assistant
referee getting the athletes’ attention, then turning control of them over to the start official.
The start official instructs the competitors to “Step-up” for a forward start, or “Place your feet” for a backstroke start. The competitors should step into place without excessive noise or
movement. The start official may give brief instructions as deemed necessary. Then, the start
official commands, “Take your mark.” Each swimmer, with no unnecessary noise or
movement, immediately assumes the desired starting position. Once the start official sees
that the swimmers have taken their position uniformly and are motionless, the signal is given
to start the race. The purpose of this is to insure that no competitor has an unfair advantage
by intimidation, position, jump or delay.
Daktronics has developed a start system that ensures reliability and fair starts for all. Its
straightforward design produces a loud sound, bright visual strobe and precise electronic
signal. The HS-200 is a portable unit that comes standard with an internal rechargeable
battery, power pack, 360° strobe, 30' (9.1 m) start cable, 15' (4.6 m) microphone cable and
microphone. Several other options are available, including the backstroke flagpole-mounting
bracket, auxiliary speakers, individual lane speakers, wireless microphone, remote strobe and
start cables to connect to other brands of timing systems, including CTS, Omega and IST.
Class A Device Statement - (Section 15.105(a) of the FCC Rules)
Note: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy. If not
installed and used in accordance with the instruction manual, harmful interference to radio
communications may be caused. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct the interference
at his/her own expense.
1.4 Important Safety Instructions
Read and understand all instructions before using.
Do not drop the horn start or immerse it in water.
This device may be used outdoors temporarily, but it is not to be permanently
mounted outdoors or left in wet weather.
This device shall not be exposed to dripping or splashing, and no objects filled with
liquid shall be placed upon it.
WARNNING! To reduce the risk of fire or electric shock, do not expose this device to
rain or moisture.
Operate the horn start system with the built-in rechargeable battery. A completely
charged battery will provide at least 15 hours of operation. Use 120 V power only
when the battery’s power is low.
CAUTION! DANGER OF EXPLOSION IF BATTERY IS INCORRECTLY REPLACED.
REPLACE ONLY WITH THE SAME OR EQUIVALENT TYPE.
WARNNING! Do not expose batteries to excessive heat, such as direct sunlight or
open fire.
Do not run the horn start’s battery dead. Charge it for 24 hours before putting the
horn start away for the next meet.
Do not let the power cord touch hot surfaces or hang over the edge of a table, which
could damage or cut the cord.
If an extension cord is necessary, use a three-pronged polarized cord. Arrange the
cord with care so that no one will trip over or pull it out.
Before using an extension cord, inspect the cable thoroughly and verify its
compliance with the local electric codes.
Always turn off and unplug the control equipment when it is not in use.
Never yank the power cord to pull the plug from the outlet. Grasp the plug and pull
to disconnect.
To avoid electrical shock, do not disassemble the control equipment or the driver
modules. Incorrect reassembly can cause electric shock and faulty operation or
permanent damage to the circuits.
WARNING! To prevent injury, the horn start, all speakers, and remote strobe must be
securely attached to a pole/wall/start block in accordance with installation instructions.

1.6 Using the Horn Start
Before Each Session
Follow these basic steps when preparing for a meet:
1. Connect the fully-charged equipment.
2. Verify that all speakers are working.
3. Test the microphone and set volume levels.
4. Test the start signal to the timing system.
5. Verify the strobe light flashes for a start.
6. Verify the HS-200 Horn Start is set to start tone. Refer to Section 2.
7. Verify that the recall signal is set to ON or OFF as desired. Refer to Section 2.5.
8. Verify that Smart Start is turned ON or OFF as desired. Refer to Section 2.5.
Introduction
During Competition
Before starting the next heat, verify the start LED is ON-READY
(Figure 3).
After the Competition
1. Remember to recharge the battery for 24 hours (Figure 15).
The connection panel of the HS-200 horn start (Figure 4) and the HS-200R (Figure 5) is where
all connection, adjustments, and status indicators are located.
The HS-200R is identical to the HS-200 with the addition of the radio receiver for the wireless
belt pack.
1. The group of four LEDs stacked vertically on the upper left corner performs two
functions. Their main function is the one for which they are labeled. The LEDs are
also used to indicate the firmware revision during power-up and to also designate
when the unit is in programming mode. See Section 2.3.
ON-READY LED indicates
when the HS-200 horn start is
ready to start the next race, in
recall mode, or not ready.
CHARGING LED indicates
when the horn start is
connected to main power and
charging the battery. In newer
model horn starts, the
charging light will be on
whether or not the power
switch is turned ON or OFF.
Older models will still be
charging if they are plugged
into main power, but if the
power switch is turned OFF,
the charging LED will not
light up.
BATTERY FULL LED will be
on if the power switch is
turned on, and the battery is
completely charged.
BATTERY LOW LED will be
on if the power switch is turn
ON, and the battery is low.
2. The MAIN/AUX VOLUME control knob sets the volume of the internal speaker built
into the HS-200 horn start plus the volume of the speaker plugged into the jacks
labeled AUX SPEAKER.
3. The LANE VOLUME control knob sets the volume of the speakers plugged into the
jacks labeled LANE SPEAKERS.
4.The POWER connection is for a universal 12 V AC power pack.
