Wipe the battery contacts of the shift system with a cotton swab moistened with isopropyl alcohol (get straight alcohol if you can, rather than the 70% rubbing alcohol mix). Remove the batteries from all components of the system except the SC-7900, including the heart rate monitor and the speed sensor.Do not let anyone play with R/C toys within 30 feet while you are doing the pairing, and turn off Bluetooth devices to be really sure.

Norcal_rider, all that I can suggest is that you try the same thing that I suggested to Cranky2. It worked for my unit when it had the same type of malfuntion. You will have to enter your gearing again, and your wheel diameter. That will have cleared all of the information in the unit. After you have re-installed the battery, use a toothpick to press the AC button on the back of the unit. From that point on it works fine.Ĭranky2, try removing the battery and then replace it.
