1. Generality
This new Radio HL615, is the next logical step in impulses transmission by TAG Heuer Timing.
It offers high quality performance, due to the technical choices made.
The Power of transmission is 100mW linked to a frequency in the range of 869 MHz offers incomparable comfort
and reliability.
Each Receiver can receive impulses (simultaneously or not) from 4 Transmitters identified by the function
"CHANNEL" (1 to 4), with a precision of 0.13 ms.
The delay of transmission is 200 ms and the distance in good condition, up to 1000 m.

3. Description of the system
3.1. Switch ON
When you switch ON the radio (Transmitter / Receiver) will display the battery level (refer to chapter
3.8 – BATT).
3.1.1. Transmitter
The transmitter works with a battery of 3V (type CR123A).
The transmitter operates permanence and therefore consumes.
To save the battery, it is recommended to switch the transmitter off when not used.
In all cases, without pulse for more than 30h, the transmitter will automatically shut off.
To switch ON, hold button SET and press TEST
To switch OFF, hold button SET and press BATT
3.1.2. Reciever
The receiver is powered with a LiPo battery.
It is strongly recommended to insure a full charge (minimum 8 hours) before using, with the power
supply delivered with the kit (HL540-1).
To switch ON the receiver, press 3 seconds the button «POWER ». A red LED is switching ON.
To switch OFF the receiver, press together button SET and POWER
3.2. INPUT (Transmitter)
Input for timing impulses (start gate, photocells – working /closing contact).
Respect the polarities
3.3. OUTPUTS (Receiver)
Output of the timing impulses isolated by opto-coupler (1 to 4 – working / closing contact).
Respect the polarities
3.4. SET
To program the TEAM (A, B, C, D) or CHANNEL (1, 2, 3, 4) and to switch OFF the receiver.
Maintain SET pressed during the changes.
3.5. TEAM
The selection of TEAM allows to get several system (4 transmitters / 1 receiver) in the same
localisation sector.
It is important that the Transmitter and Receiver are set with the same TEAM.
To visualise the team set, press button TEAM
To change team, press together the button SET and TEAM.
3.6. CHANNEL (Transmitter)
Set the channel of transmitter used (1, 2, 3or 4).
It is related to the Receiver OUTPUT (banana output)
To visualise the team set, press button CHANNEL
To change team, press together the button SET and CHANNEL.
3.7. TEST (Transmitter)
The button TEST allows to transmit an impulse to verify the communication.

3.8. BATTERY
To check the state of the battery.
For Transmitter : 4 Led + 2 Beep : > 75 %
3 Led + 2 Beep: > 50-75 %
2 Led + 3 Beep : > 25-50 %
1 Led + 3 Beep : < 25 % warning case / change the battery.
For receiver : 4 Led : > 75 %
3 Led : > 50-75 %
2 Led : > 25-50 %
1 Led : < 25 % warning case / charge the battery
The state of the battery is also available when switching ON
4. Receiver charge
The receiver works with a LiPol battery of 3.7V / 2200mAh
Use our 12V power supply (HL540-1) with 500mA minimum.
The LED Power show the charge state
Receiver OFF: Charge active : Slow flashing LED
Charge Finished: Led OFF
Receiver ON: Charge active : Fast flashing LED
Charge Finished: Led ON
The full charge could take up to 4 hours.
The autonomy is up to 48h (with impulses every 10 secs = 6900 impulses)
The receiver is automatic switching in Stand-by if any impulses is detected during 24h.
Warning :
It is forbidden to charge the battery with a temperature lower that 0°C and higher that 40°C

5. Transmitter change battery
The transmitter is working with a battery 3V (type CR123A – 1400mAh)
The button BATT allows to check the battery level (see chapter BATT – 3.8)
It is recommended to change the battery when test battery show only 1 LED ON
To change battery.
1) Remove the two screws with a torx screwdriver (n°9)
2) Remove gently the bottom cover.
3) Remove the circuit where the battery is fixed
4) Exchange the battery (CR123A) and replace the circuit to the Transmitter. Warning that the 6
connexion pins are well placed.
5) Screw back the cover without forcing
Standard autonomy: Transmitter OFF: 365 days
Transmitter ON : 45 days (impulses every 10 sec)
Transmitter switches automatically in Stand-by if none impulse during 24h.

6. Transmission
The transmission between Transmitter and Receiver is 200ms, with a precision of +/- 0.13 ms
Once the receiver receives an impulse, the LED of channel (1 to 4) will switching ON during 0.5s
In same time the LED on right will switch ON to the reception signal power
4 Leds ON Good (< -60 dBm)
3 Leds ON Acceptable (-60 à -70 dBm)
2 Leds ON Low (-70 à -80 dBm)
1 Leds ON Very low (> -80 dBm)
Transmitter and Receiver provides a visual (LED) and audio alarm, should an external input remain in short-
circuit.
This feature allows you to observe the status of TAG Heuer’s new “direct-response” photocells (HL 2-31, HL
2-35 and HL 2-32 – serial number 7000 or higher), and allows the timekeepers to instantly determine if a
photocell is out of alignment.
WARNING :
For proper operation it is essential that the transmitters and the receiver are not closer
than 2 meters.
WARNING :
It is forbidden to operate transmitter without antennas, it may damage the electronic radio transmitter.
7. Installation recommendation
For good transmission, it is recommended that antenna are placed 1m above ground
Transmitter/Receiver should be place vertically and antenna in up direction
A direct view between Transmitter and Receiver will improve performance
Protect Transmitter / Receiver in case of rain (with a platic bag) After using the system in high humidy
ambiance (rain), it is recommended to place them on a warm environment (out in the open air) to prevent
any rust or electronics damage
Warning :
Radio systems using a similar range of frequency (869 MHz) can disrupt the transmission.
It is strongly recommended to test before the race, and have a back-up system.
