NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation.

If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

-- Reorient or relocate the receiving antenna.

-- Increase the separation between the equipment and receiver.

-- Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.

-- Consult the dealer or experienced radio / TV technician for help.

NOTES:

THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE
CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. ANY CHANGES
OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE GRANTEE OF THIS DEVICE
COULD VOID THE USER’S AUTHORITY TO OPERATE THE DEVICE.

Pairing: Consult your ANT + or Bluetooth Smart device’s instructions for pairing. Sensor
will need to be activated directly before pairing process.

Sensor Activation: To verify proper magnet install, spin wheel or turn crank more than
two revolutions. Initial sensor activation and magnet alignment will be indicated by the
LEDs flashing up to 10 times.

Please Note: The sensor will stay active for at least 2 minutes although the LEDs no
longer flash.

Bluetooth Smart Connection: Install and activate sensor. Turn on your phone’s
(or other compatible device) Bluetooth capability. Open the desired cycling app and follow
instructions for Bluetooth Smart sensor connection. Please note, Bluetooth Smart devices
do not always appear in your phone’s settings, even when connected. All apps collect,
share, and display speed and cadence information differently.

Remove the pedal and
install cadence magnet on
nondrive side crank arm
with thick side nearer the
chainstay. Use cadence
magnet band that gives
the best fit.

For carbon bikes, place
magnet 135mm or
145mm from the center
of the bottom bracket to
the center of the magnet.

Hint: If the magnet is aligned
but the LED does not
illuminate, place a cadence
band shim underneath the
appropriate magnet.

Verify magnet is aligned with
sensor by illumination of
green cadence sensor LED
as crank is turned. LED will
illuminate for the first 10
revolutions. Align magnet
with tech mark on alloy
bike’s chain stay.

PAIRING AND SENSOR ACTIVATION

Speed magnet (carbon
bikes) Snap magnet onto

inside/trailing edge non-drive
side spoke. Some carbon
frame/wheel combinations
may require magnet to be
flipped so the thin side faces
sensor.

Speed magnet (alloy bikes)
Tighten wheel magnet on
spoke for alloy bikes

Align speed magnet with
tech mark on DuoTrap S.
Verify sensor is aligned with
magnet by illumination of red
speed sensor LED as wheel
is rotated. LED will illuminate
for the first 10 revolutions.
