4. Calibrate your Newton+ with a "Cal Ride"
To calibrate your Newton+ you need about 10 minutes to perform a Cal Ride. The Cal Ride
customizes your Newton+ to your bike, and gets it ready for power measurements. This is
an easy, leisurely ride; there's no need to race, and no reason to worry!
Here's how to do the Cal Ride:
1. Pick a quiet, low-traffic place to do a solo (no drafting allowed) Cal Ride.
2. Wake up the Newton+. Speed is shown in the top window. You'll see "----W" in
the center window, indicating that your Newton+ requires a Cal Ride, and that it
can't report power numbers until after the Cal Ride has been completed.
3. Start riding. After 8 seconds the Newton+ screen changes. "Cal" appears in the
middle window, and "Start" flashes in the bottom window.
4. When you're ready to start the Cal ride, click the center button to start the
Cal Ride.
5. The top window shows bike speed, the center window alternates between "Cal"
and distance traveled, and the progress bar fills as you ride.
6. During the Cal Ride you can bike at a leisurely pace, and it's OK to stop if
needed. Your Cal Ride will be unaffected.
7. Ride for five minutes, until "go back, turn 180 degrees" flashes.
8. If you still need to keep going a ways before turning safely, it's OK. When safe,
slow to a stop, turn around, and ride back to the starting point.
9. The progress bar empties as you ride back. Keep riding until the progress
bar is completely empty, and "Cal Done" flashes.
