: APPENDIX 5 ON PAGE 54 SUMMARIZES THE VARIOUS FEATURES AVAILABLE FOR 

EACH NEWTON MODEL, ACCORDING TO SERIAL NUMBER 
 
Below is a description of advanced features and their operation. 

 

INDOOR TRAINER MODE 

 

The Indoor Trainer mode allows you to measure indoor power with over 100 different 
models of indoor trainers and rollers.  Consult the ISAAC software, “Device/Edit Trainer 
Settings…” for a complete list of supported trainers and rollers. 
 
When using the indoor trainer mode your Newton measures the speed of the rear wheel 
and, using the speed/power curve for your particular model of indoor trainer, reports the 
power required to achieve the measured rear wheel speed. 
 
Speed/power curves used by the Newton are obtained from the trainer manufacturer, or 
users who have measured the curves with a DFPM. 
 
To see if your Newton includes the indoor trainer mode, using ISAAC go to Device/Unlock 
Feature….  Click the “Get Unlock Status...” button.  If indoor trainer is enabled you will see 
“Trainer Feature” listed:
