❑ Set the height of the beacon to be level with the lap timing sen-
sor on your vehicle. Set the beacon level so that it emits a hori-
zontal beam.
❑ Choose a position for the beacon between 2 and 30 metres (6 to
95 feet) from the vehicle as it passes within each lap.
❑ Avoid locating the beacon where the sun is directly behind it.
This is because the lap timing sensor will be unable to distin-
guish the signal from the beacon against the intense infrared
background signal from the sun.
❑ If you intend to use the beacon for extended periods in very hot,
sunny conditions, protect it from direct sunlight.
❑ Protect both transmitter lenses of the beacon from water spray.
During wet conditions, fit a protective peak over the beacon. Do
not cover the beacon, for example using a plastic bag.
2. You must supply the beacon with power from a convenient 12V DC
source. A sealed lead–acid battery with a rating of at least 2.5 Ah is
ideal for this purpose. From a fully charged condition, such a bat-
tery will provide continuous operation for approximately 15 hours.
Operation of the trackside beacon is simple:
1. The beacon begins to operate as soon as you connect a suitable DC
supply.
2. There is a two–colour status LED on the beacon:
