The Infrared transmitter, or Beacon as it is often called, is set near the edge of the track to trigger a lap time to the onboard system of a passing vehicle. All beacons have a common frequency so one only transmitter per track is required. The beacon transmitter may be powered by the internal battery pack, composed of 8 AA batteries, or by a 12 V external power source.
The beacon transmitter has two operating modes: LOW power and HIGH power. The low power mode has to be used when the track is less than 10 m (30 ft) wide, while the high power mode has to be used when the track is up to 20 m (60 ft) wide. To activate this function, please open the beacon transmitter and place the clip ( located directly below the battery attack to the beacon transmitter board ) either over one of the two connectors (for LOW power mode) or over both connectors (for HIGH power mode). When the beacon transmitter operates in HIGH power mode, both front power led lights up.
When the transmitter operates in HIGH power mode, it is strongly recommended to use a 12 Volts external battery.
