Red LED: On or OFF;
Wave Length: 940nm.

2 x AA batteries are used as power supply for IR transmitter.
Voltage gradually decreases when batteries are used. The receiving distance will be shortened with the increasing usage time of the batteries. So please take this factor into consideration and put the IR transmitter at a proper position in advance of usage, in case that the receiver(timer) miss out signal.

Things to note:
As the IR signal is interfered by sunlight, the receiving distance of IR signal will be shortened when the sunlight is strong. We recommend you to place the IR transmitter closer to the receiver when the sunlight is comparatively strong.
Do not put the IR receiver or IR transmitter face directly to the sunlight.
Do keep the IR receiver and IR transmitter at the same height.
Do make the IR receiver face directly to the position of IR transmitter.
Avoid placing the beacon on the corner, as bike will lean and the chance of missing signal will dramatically increase.
Always change the batteries after about 5 hours’ usage.
Please take out the batteries during long time idle.
Please turn off the power once it is not in use.
Do not use the product outdoors in rainy day.

The signal receiver is built in the timer, make sure the receiver is exposed to the “signal wall” created by the transmitter;
The laser pointer helps to build the signal wall; Make the “wall” as vertical to the track as possible;
When you are not able to expose the signal receiver to the “signal wall”, try to turn the “wall” to different angles
