Performing a manual zero offset (optional)
1.
Rotate the cranks to ensure the power meter is awake. A blue light will flash every eight
seconds to confirm that the unit is awake.
2.
Select the zero offset, calibration or zero reset function of your bicycle computer or smartphone
app.
3.
With compatible display units, you should see a confirmation message when the zero offset
is finished.
To charge the integrated battery of the SPM
2,
connect the included magnetic charging cable to
a 5V USB charging source and to the unit’s charging port (
Caution:
Make sure than the port is
clean and dry before plugging in the cable). A green light will flash briefly to confirm
connection and then the LED will turn red during charging. Once the battery is fully charged,
the LED will turn off to let you know that you can unplug the charging cable.
A full charging run can take around 3 to 4 hours. DO NOT use your power meter while
charging the battery.
The integrated battery of the SPM
2
allows up to 120 hours of riding after a full charge. In
compatible devices, the screen can show five levels of battery life (sometimes regarded as:
new – good – ok – low – critical). Once it reaches the “low” level, the power meter will have
several hours of normal and accurate measures. It is recommended to charge the battery before
it reaches the “critical” level to avoid measure inaccuracies.
The power meter unit will enter standby mode after five minutes of inactivity to save battery life.
To activate the unit again, rotate the cranks.
