This speed sensor showed a low battery when I used it a couple of weeks ago, then it was dead the next two days. I replaced the battery and moved it onto my newest bike. Today, I noticed that I was getting the pause symbol (the two vertical bars) repeatedly, and when I tried to get the timer going again, I would get the "sensor-name Connected" message. After about ten pauses, I disabled the sensor, and the rest of my ride was drama free.
I also changed the battery on another speed sensor and rode that bike for about 20 minutes. I didn't have any problems with that unit. The two "new" batteries came from the same package, so they're the same age.
Any suggestions to get this little sucker working again?
