5.4.1.3.1 Mode
Depending on the position of the two tripods (e.g. outside the 8 lanes of an athletics track) and how close to
the photocells the athletes will pass, the photocells can be set as follows:
In 'Normal' mode the maximum distance between photocell and reflector is 7 meters, whereas in 'Strong'
mode it is 12 meters. The latter, though, does not record passages, if the athlete passes too close to the
photocell (minimum distance of 50 cm).
5.4.1.3.2 Radio Power
The Radio Power parameter indicates the duration of the impulse transmission set for "Normal" mode at
1.2 sec. and for "Short" mode at 0.4 sec.
As explained in chapter 2.3.1, lowering the impulse duration (setting Radio Power to "short") has some
advantages if there are two photocells, which are very close one to another, but decreases the transmission
quality in the long run and therefore system reliability.
