HEART2feel free/X SOFT BELT
The chest strap must be positioned
around your chest. when correctly
placed, it sends heart rate informa-
tion to the watch. Located on the
wrist, the watch displays the heart
rate and provides various extra infor-
mation (target zone, intensity of exer-
cises) to manage and optimize your
fitness and training. The soft belt will
be connected with to clips at the
sensor case. The rubber areas have
to be placed on the skin (see photo
below)
USING THE
HEART2feel free/X SOFT BELT
The Heart2feel free sensor is using an
analog RF communication, so no need
for any pairing. You can use it like des-
cribed in the manual of the matching
product (MIXfree & MACRO free)
The Heart2feel X sensor has to be pai-
red like described in the manual for
MIXpro & MACRO X – settings - pairing
1_ Connect the soft belt with the sensor
on one side. Push one bottom of the
heart rate sensor on the strap.
2_ Wet both sensors on the back (rub-
ber area) of the heart rate monitor to
create a strong connection between
your chest and the transmitter
(for extremely dry skin use some
special gel)
3_ Wrap the strap around your chest
and attach it to the other side of the
heart rate monitor.
NOTE:
The o-synce logo should be
right-side up.
4_ Bring the o-synce product you want

NOTE:
If or heart rate data does not
appear or if you have erratic heart rate
data, you may have to tighten the strap
on your chest or warm up for 5–10 mi-
nutes. If the problem persists, you may
have to pair the sensors.
Reapply moisture to the sensors. Use
water, saliva, or electrode gel. Clean the
sensors. Dirt and sweat residue on the
sensor can interfere with heart rate si-
gnals.
Synthetic fabrics that rub or flap against
the heart rate monitor can create static
electricity that interferes with heart rate
signals.
NOTE:
In cold conditions, wear appro-
priate clothing to keep the heart rate
monitor near your body temperature.
Accuracy may be degraded by poor
sensor contact, electrical interference
and receiver distance from transmitter.
Strong electromagnetic fields and some
2.4 GHz wireless sensors can interfere
with your heart rate monitor. Sources of
interference may include very high vol-
tage power lines, electric motors, micro-
wave ovens, 2.4 GHz cordless phones,
and wireless LAN access points. After
you move away from the source of inter-
ference, your heart rate data should re-
turn to normal.
NOTE:
Stay 10 m away from other
ANT sensors while pairing. Bring the
o-synce product within range (3 m) of
the heart rate monitor while pairing. If
the problem persists, replace the bat-
tery.
TO REPLACE THE BATTERY
1_ Locate the circular battery cover on
the back of the sensor.
2_ Use a coin to twist the cover coun-
er-clockwise until it is loose enough
to remove.
