12 Beacon Receiver
zero, this special case allows the receiver to report all beacons with the same
Mode setting for split beacon use. The output of the beacon receiver is
encoded with the beacon number to allow the beacon transmitter number to
be identified, this is normally only required for split beacon use so that the Lap
Beacon may be identified.
• Turn the power off before adjusting the number, to avoid accidental
damage to the electronics and to ensure that the power is cycled before
use. Changing the ID switches while the power is on will have no affect
until the power is cycled.
• Be careful to read the labels for the switches, located on the inside of the
lid, so as to set the switches correctly.
LED
The Red LED will be ON when it is receiving a valid number.
The LED will glow dimly when receiving a signal that is the incorrect number
or an infrared signal is being received from some other source.
The LED will also glow dimly if the receiver is picking up interference from the
car ignition or a radio transmitter. This is undesirable and must be rectified
before the receiver will operate reliably, as the interference signal can mask
out the real signal which will result in missed beacons.
