3.2. ACTIVATION AND DEACTIVATION
Your Bike Pod is activated automatically when the spoke magnet passes the
speed sensor i.e. when the front wheel spins. It stays active throughout the
cycling trip and for half an hour after the sensor has stopped getting readings
from the magnet.
3.3. CONNECTION
To use your Bike Pod, you must establish a connection between it and your
Suunto t6. This can be compared to listening to a radio. To be able to receive
the radio broadcast signal, you need to switch the radio on. Similarly, for your
Suunto t6 to be able to receive the signal from your Bike Pod, the devices must
be connected. You need to establish the connection every time you want to use
your Suunto t6 with your Bike Pod.
1. Spin the front wheel so that the spoke magnet passes the sensor.
2. Select
Connect
in the Speed/Distance menu of your Suunto t6. Suunto t6
informs you when the device has been found.
If the connection fails, Suunto t6 displays the message ‘
NO
DEVICES
FOUND
’. In
this case, spin the front wheel again to ensure that the Bike Pod is active and try
again.
3.4. CALIBRATION
Suunto Bike Pod measures your bike’s speed and distance from the rotation of
the front wheel. Since a single rotation of a smaller wheel does not take you as
far as that of a larger wheel, your Suunto t6 needs a specific calibration factor
that takes the tire size into consideration. For the measurements to be accurate,
you need to adjust the calibration factor of your Suunto t6 to match that of your
wheel size.
To define the exact calibration factor, measure the tire circumference or cali-
brate your Bike Pod using a known distance.
3.4.1. Measuring the circumference manually
1. Set a measuring cord on the floor.
2. Ride along the cord so that the tires rotate fully at least once. (The measure-
ment is more accurate if you sit on your bike and do not just push it along the
cord.)
3. Measure the covered distance with the accuracy of a millimeter. (Divide the
distance with the number of rotations if more than one rotation.)
4. Divide the circumference by 2050 (e.g. 2096 / 2050 = 1.022439 = 1.022).
3.4.2. Calibrating the Bike Pod using a known distance
1. Select Connect in the SPD/DST menu of your Suunto t6.
2. Reset the distance measurement at the startline.
3. Press START/STOP in SPD/DST mode and cover a known distance with
your bike.
4. Press START/STOP to stop the measurement.
5. Select
Calibrate
in the SPD/DST mode.
6. Select
Bike POD
and replace the measured distance with the correct dis-
tance.
3.4.3. Calibrating the Bike Pod using the calibration factor table
You can also calibrate the Bike Pod using the calibration factor table.The data in
the table comes from various tire manufacturers and the European Tire and Rim
Technical Organisation. Because of the differences in the tire pressure, tread
pattern, and measurement methods, the table is only indicative.
1. Check your tire size, and find the appropriate calibration factor in the table
(see Appendix).
