How to install the heart rate sensor (HR-11)
Heart rate is measured when the heart rate sensor is worn on the chest.
Warning!!!
: This product must NOT be used by those who have a pacemaker.
•
To avoid measurement errors, it is recommended to moisten the electrode pads with water.
•
If your skin is sensitive, the electrode pad may be moistened with water and worn on a thin
undershirt.
•
Chest hair may interfere with the measurement.
1
Attach the heart rate sensor to the HR strap.
Push it in until it clicks.
2
Insert the HR strap hook to the other end of the strap.
Wear the heart rate sensor with the HR strap, and adjust the length of the HR strap to fit
your chest size (under bust). Fastening the strap too tightly may cause discomfort.
* Wear the heart rate sensor so that the top of the sensor faces up.
* Ensure that the electrode pad is in direct contact with the
body.
* When your skin is dry, or wearing the heart rate sensor on
top of your undershirt may produce measurement errors.
To avoid errors, moisten the electrode pad.

1
Temporarily secure the magnet
1
Temporarily secure the cadence magnet inside the crank
with nylon ties, so that it faces the sensor zone on the
CADENCE
side.
2
Turn the sensor arm, and temporarily secure the wheel
magnet to the spoke that faces the sensor zone on the
SPEED
side.
* When the speed sensor is not positioned appropriately in respect
to the two magnets (of
CADENCE
and
SPEED
), move the speed
sensor back and forth so that it is positioned properly. After you
move the speed sensor, adjust the position so that the two mag-
nets face the relevant sensor zone.
2
Adjust the distance to the magnet
1
Tilt the speed sensor so that the distance be-
tween the cadence magnet and the
CADENCE
side of the speed sensor is about 3 mm, and
firmly secure it with the nylon ties.
2
Turn and adjust the sensor arm so that the
distance between the wheel magnet and the
sensor arm is about 3 mm, and firmly tighten
the sensor screw.
3
Securing various parts
Firmly tighten the nylon ties, sensor screw and magnet of
the speed sensor, and check for any loosening.
* For steel axle pedals, the cadence magnet can be magneti-
cally secured on the pedal axle. Make sure to remove the
double-sided tape from the magnet when doing this.
