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.

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.

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.
