at which the head meets the cylinder to get the most
accurate, consistent readings.
• Plug the temperature sensor into the port marked
TEMP in your receiver. The Telemetry screen on the
DX3R PRO should now display the room temperature.
TEmPEraTurE sENsOr (ElECTrIC) (sPm1451)
A Thermister-type temperature sensor is available that
can be taped to the battery or motor to monitor real-time
temperature. You can use transparent tape to attach the
sensor for temperatures up to approximately 250°F
high. High-temperature tape is needed for temperatures
exceeding 250°F.
Temperature Sensor Installation (Electric)
• Tape the temperature sensor to the area you wish to
monitor (normally the batteries or motor).
• Plug the temperature sensor into the port marked
TEMP in your receiver. The Telemetry screen on
the DX3R PRO transmitter will now display room
temperature.

The lap counter displays the lap time. In order to use the
lap timer, an optional lap trigger, onboard telemetry module
(SPM1325) and SR3001 receiver (SPM1205) are required
for the lap counter. The lap counter/timer system utilizes
an infrared sensor in the car and the lap trigger projects an
infrared light across the track that triggers the sensor when
the car passes. A Lexan mount is provided to allow easy
mounting of the lap counting sensor in your vehicle.
Note: The lap sensor must be mounted in
visible sight of the lap trigger. Normally this
means just inside the side window. If the
windows are painted, it will be necessary to cut
a small hole in the body to allow the IR light to
trigger the sensor.
Lap Counter/Timer Installation
• Servo tape the lap sensor to the Lexan mount.
• Determine the mounting position that will place the
sensor behind the side window.
• Cut and/or bend the Lexan mount to position the sensor
in the appropriate position and servo tape the mount in
place.
• Plug the lap sensor into the L (lap) port in the telemetry
module.
laP TrIggEr (sPm1330)
The Lap Trigger is placed next to the track and projects
an infrared beam of light across the track that triggers the
infrared sensor in the car each time it passes. The receiver
records each lap time and sends that information to the
transmitter where it is displayed. A programmed delay of 2
seconds prevents double lap counts.
Installing the Lap Trigger Battery
Use 3/32” and 5/64” hex wrenches to unscrew the case and
install the 9-volt battery as shown. Reinstall the case, being
careful not to over-tighten the screws.
Note: A typical 9-volt battery will power the lap
timer for 9 hours.
Mounting the Lap Trigger
Mont the lap trigger 8 inches to 36 inches (20 to 91cm)
above the racing surface facing outward from the track.
Facing the trigger outward keeps the IR beam from crossing
the track in more than one lane preventing unwanted false
triggering. Hook and loop strips make mounting easy.
Only one lap trigger is necessary at each track, as a single
infrared beam will trigger the lap timer in all cars.
