Dear MyChron Light TG Owner
Your new Instrument is the evolution of MyChron Light MCL.

different time counter settings.
The small size of MyChron Light TG allows you to install it
anywhere without problems.
MyChron Light TG standard version is a plug and play
instrument. There is nothing you need to do: only switch it
on and it starts recording. Moreover, the automatic switch
off after 20 minutes of inactivity avoid undesired battery
exhaustion.

The Infrared Transmitters
Your MyChron Light TG is an intelligent lap timer and can
detect the signals of two different transmitters: the lap
transmitter and the split transmitter. These two objects
differs in the kind of signal they emit; MyChron Light TG
can distinguish their signals, and thereby record a split time
or a lap time.
With these new useful transmitters you will no more throw
away all your data if only missing one signal.
While with the old transmitters lap signal and split signal
where the same and if you missed one signal your
instrument shifted start / finish line, with these new ones,
also if you miss a split or a lap signal, when the instrument
gets the next lap signal it re-starts calculating splits and laps
correctly and does no more shift start / finish line.
Your standard kit includes one transmitter, the lap one. The
split transmitter is optional.

How to install MyChron Light TG
Please follow carefully these few instructions in order
to preserve your instrument and record reliable data.
•Choose a place where the lap timer will not be in contact
with oil or fuel nor too close to heat sources.
•Your MyChron Light TG can suffer vibrations, this is
why it is arranged with four thread holes (highlighted with
four arrows in figure 4) you can use to install it.
Figure 4 - MyChron Light TG rear view
If you have bought an optional externally powered
version of MyChron Light TG, you will find two cables
coming out from the bottom of the lap timer, you should
connect these cables to an external 7-15 V power source
