Cadence and Speed, but no Power..."do CAL"

[jaan_k]

Hi.
When I first started using my Newton +, I went directly into TRNR mode and used it with my Kurt Kinetic Pro trainer for 4 months without hassle (no outside riding this winter in Michigan). Now I'm getting the prompt "do CAL" on the watts line. The cadence is registering, as is the speed. Must I perform a ride calibration, or is something else going on? Again, I didn't have a problem straight out of the box.

(for what its worth, I love my iBike Newton +)

Nevermind...I did a calibration ride, and then rebooted. Everything works fine again.
