Range
The MoTeC Lap Beacon system has a range of up to 40m (130ft).
Note: If the receiver is aimed through tinted glass or tinted acrylic sheet
(Plexiglass/Perspex) the range may be reduced substantially. This needs to
be checked for the particular installation by checking the operating range.
Clear glass or clear acrylic sheet is normally OK.
In all cases the range should be tested to ensure that it is at least 1.5 times
the required range. For example, if a range of 10m is required then the tested
range must be at least 15m. The additional range allows a margin to ensure
that a reliable signal is received under all conditions.
See Appendix A – Range Specification for more detail.
Alignment
Both the transmitter and receiver must be aligned to within 5 ° of optimum
(preferably 2 °)
