Make sure to select "Simulator" also in the "Network profile" on the settings menu. Cadence Bell This option will enable a cadence signal for each revolution when the signal is triggered.

19 Troubleshooting Troubleshooting 1/2 Power LED doesn't switch on Check the power supply and the power cable connection Cadence LED doesn't flash for each revolution Check the position of the sensor cable or see PowerMeter battery issues Power and Torque values shown on "Main" screen are not accurate Ensure the PowerMeter settings are correct: check the slope and the zero offset values on Settings-Powermeter window Candence value is visible but not accurate Check the position of the sensor cable No connection between the computer and the SRM Ethernet Torque Box Check the network configuration on your computer, ensure the ip address is the same subnetwork of SRM Ethernet Torque Analysis box SRM Ethernet Torque Box's IP adress lost Use the DeviceInstaller Utility to find and setup a new ip adress The revolution graph is not in the right position Check the relative parameter on "PowerMeter profile" considering the activation point Position of the sensor cable Check position of sensor cable to ensure it is passing over the cadence switch at a distance in between 3 and 5 [mm].

20 Troubleshooting 2/2 PowerMeter battery issues The PowerMeter battery is not self-replaceable. You will need to send it to the Service Center for replacement. ATTEMPTING TO REPAIR IT YOURSELF WILL INVALIDATE THE WARRANTY, and could cause permanent damage to your PowerMeter. Battery life of the PowerMeter will vary between PowerMeters. General expectancy of wired systems: DuraAce/FSA/track approximately 1500 hours of use Pro and Amateur approximately 1000 hours of use Cannondale/Specialized approximately 750 hours of use General expectancy of wireless systems with ANT technology: DuraAce/FSA/Pro approximately 1400 hours of use Cannondale/Specialized approximately 700 hours of use If the variance of your zero-offset begins to fluctuate more than normal and your hours of usage is in-line with the above, your battery likely needs to be replaced. Please download the Service Form and send your PowerMeter back to the Service Center for replacement.

21 Activation point Activation point 1/1 Changing the activation point for the revolution is necessary when you wish to view the revolution with a specific starting point. Your powermeter triggers cadence at the point where the reed switch inside the powermeter passes the sensor. To change the activation starting point for the torque revolution, you must first measure the angle in degrees of your sensor cable (see picture below). This means the revolution starts at 42 degrees from the vertical position If you want to have the revolutions started from 90 degrees just set the activation point to 48 (90-42=48).

22 Network configuration Network configuration 1/2 Check the SRM Ethernet Torque box ip address; this address is printed on the bottom of the outer case. See "Default IP adress" label. Choose a free and valid ip address on the same subnetwork of your computer: i.e Configure the ip address If you are using MS Windows Seven Press "Start" button Open "Control Panel" Select "Network and Sharing Center" Click "View Network Connections" Right click on the connection you need to change (i.e. Lan) than "Properties" On "Network" tab double click on "Internet Protocol Version 4 (TCP/IPV4)" Insert the choosen IP address (see point 2.) If you are using Apple OSX Launch "System Preferences" from the Apple menu (or Spotlight) Click on the "Network" icon In the lower right, click on the "Advanced" button In the pulldown menu next to "Configure IPv4 "select "Manually" Insert the chosen ip address
