Congratulations on the purchase of your Tx Junior Pro transmitter ! This
device has been designed to be convenient and simple to use. In this guide
you will find all the information about how it works.
OVERALL FUNCTIONING

USE OF YOUR TX JUNIOR PRO

YOUR TX JUNIOR PRO
The Tx Junior Pro is the versatile transmitter of the Freelap system. It can
be quickly set as start, lap, or finish transmitter. Thus, it lets you get both
your lap times and your split times.
It emits a magnetic field automatically detected by your FxChip or FxChip
BLE transponder during its passage.
PREREQUISITES
Your Tx Junior Pro transmitter is part of the Freelap system. In order to
make it work, you must attach transponder(s) to the athlete(s) and use
the MyFreelap app (consult the corresponding user manuals for more
details).
SIMULTANEOUSLY USE TX JUNIOR PRO ON ADJA-
CENT LANES
The Tx Junior Pro can cover 2 lanes: 1 lane of 1.22m on each side of the
transmitter. Athletes can run at the same time on 2 adjacent lanes.
To time more lanes, you can add transmitters.
/! \ Do not superimpose magnetic fields:
If you want to time on 4 lanes, 2 transmitters are enough: 1 to cover the
lane n°1 and n°2, and 1 other to cover the lanes n°3 and n°4.
.
ASSOCIATE IT WITH OTHER TRANSMITTERS
To make Freelap system work, you must have a transmitter set with the
code "Finish" on your track.
The Tx Junior Pro is a versatile transmitter, so you can use several Tx
Junior Pro on your track (set as start, lap or finish transmitter). You can
also use it in combination with other Freelap transmitters (e.g.: you can
use the Tx Touch Pro transmitter as start transmitter).
Transmitters must be spaced at least 10m apart, with a minimum space
time of 0.7 second.
BUTTON AND LEDS OF YOUR TX JUNIOR PRO
TURN ON AND SET YOUR TX JUNIOR PRO
• To turn on the transmitter simply press the central "ON" button for 1
second.
• Once the transmitter is on, press the central button again to select the
desired code (Start = for start transmitter/ Lap = for intermediate transmit-
ter/ Finish = for finish transmitter). Each press of the central button
switches you to the next code. The LED of the selected code flashes.
PLACE YOUR TX JUNIOR PRO ON THE TRACK
• Place the Tx Junior Pro on the ground (do not raise it) .
• The transmitter has a detection field of 1.5m, so it must be placed:
- at the edge of the track, less than 1.5m from the athlete's pass (so that
the transponder of the athlete crosses the detection field).
- Tx Junior Pro transmitters must be at least 10m apart (between them, or
with other transmitters).
- For an optimal accuracy, you should start to run 20m before the start
transmitter (or at least 5m before).
