Adjust and Test
1. Unscrew and move the sensor arm to within 5 mm of the
spoke magnet. You can also tilt the GSC10 closer to either
magnet for improved alignment.
2. Press the Reset button on the GSC10. The LED light turns
red, then green. Pedal to test the sensor alignment. The red
LED blinks each time the crank arm passes the sensor, and
the green LED blinks each time the wheel magnet passes
the sensor arm.
Note: The LED blinks for the first 60 passes after a reset.
Press Reset again if you require additional passes.
3. When everything is aligned and working correctly, tighten
the cable ties, sensor arm, and spoke magnet.

Install the Spoke Magnet
Attach the spoke magnet by unscrewing the magnet from
the plastic piece. Then place the spoke in the groove of the
plastic piece and tighten slightly. The magnet can face away
from GSC10 if there is not enough room between the sensor
arm and spoke. Make sure the magnet is aligned with the
sensor arm indication line.
