Here is a list of items to be aware of when using a beacon transmitter:
• Make sure the beacon receiver is mounted on the vehicle so that the signal has
a clear path to the receiver.
• Direct sunlight into the receiver can cause a lap to not register. Install the
receiver with the overhang on top. If the rising or setting sun is pointed directly
into the receiver, set the transmitter on high power.
• Have the beacon transmitter on standard power if it is within 10' to 25' of the
receiving instrument. Set the beacon on high power if it is over 25' from the
receiving instrument.
• Beacons transmit their signal in a cone shape. If you are too close to the beacon
you may miss the signal or intermittently pick it up. The faster the kart, the
farther from the beacon transmitter signal it should be.
Manual Lap Switch Placement (Optional)
The Lap switch is used in place of the infrared beacon receiver. It should be
mounted to the steering wheel within thumbs reach of the driver. This switch
requires a 15/32" mounting hole for installation. Mount the switch in a position
that will provide easy access while driving. Tie the coil cord to the steering column
where needed to prevent it from interfering with the driver.
Route the sensor cable to the pigtail with the white boot on the back of the
instrument.
If the Lap switch is not used, leave it’s input connector open. Do not use a shorting
plug.
The DT-40K uses One AAA Battery (not included)
The DT-40K can run, without a backlight, for 200 hours on one AAA battery.
When using the backlight, one battery will power the instrument for 50 hours.
With the front of the instrument facing you, remove the left end cap. Remove the
battery from the holder. Observe polarity when replacing the battery. Replace the
end cap.
Steering Wheel Mount
Attach the three slotted holes on the large side of the mount to the bolts on the
center of your steering wheel. Place the nuts on the back of the instrument through
the two holes on the other side of the mount. Slide the instrument firmly to the
side to lock it in place. Adjust the nuts on the instrument for a tight fit.
