CHAPTER 1: STARTING OUT Thank you for purchasing the PowerTap Joule GPS. This user guide is just one of the resources to help you understand all the features the Joule GPS has to offer. Please visit www.PowerTap.com to: • Learn more about the Joule GPS and the PowerTap system of products •...
Should the battery become completely discharged (no partial Micro-USB charge remaining), plug the Joule GPS into a computer or AC wall adapter, press the reset button on the back panel of the Joule GPS, and the charging process will begin.
DASHBOARDS and BUTTONS Press any button on the Joule GPS to turn the unit on. The display will briefly show the date, time, some user totals and the firmware version, then begin acquiring the GPS fix on your current location. One of 5 Dashboard screens will be displayed at this time.
Page 7
BUTTON and DASHBOARD DETAIL There are three buttons on the sides of the Joule GPS and one large button below the screen. The screen is divided into 3 display areas. The Title Bar, displays time, temperature, compass, and battery level.

CHAPTER 2: JOULE GPS OVERVIEW & SETUP MAIN MENU The Main Menu is your home base. Enter the Main Menu to stop and save rides; review ride history; create, edit, select, and pair Sensors; activate Training features; define individual Users; and configure the Device.
(e.g. PowerTap, Cadence, HR strap, Speed). A default User is already defined within the Joule GPS. You can either edit the settings associated with that User or create a new user by selecting Add a User.
CHAPTER 2: JOULE GPS OVERVIEW & SETUP SENSORS & PAIRING Pairing is a term used to describe the association of your Joule GPS with a particular sensor that is broadcasting an ANT+ signal (e.g. a PowerTap hub, a Heart Rate strap, a remote cadence sensor, a remote speed sensor, etc.).
TIP : Dashboards are fully customizable. 3 to 6 of the 23 available advance through metrics can be displayed in each dashboard. See Chapter 8 for Dashboards display options and Appendix C for a full list of metrics. Joule GPS User Guide page 11...

To initiate or stop an interval press the large [INTERVAL] button on the front of the Joule. When viewing dashboard metrics, the Joule GPS allows 2 types of views: Ride View and Interval View. Ride View displays metric values related to the entire ride from the start to the current point in time. Interval View displays metric values related to the current interval.

Pair All Select “Pair All” to scan for all sensors awake and in broadcast range. The Joule GPS will display the ID of each sensor found. Selecting Yes, when a sensor's ID is displayed, will link the sensor to the new bike definition (by pressing the +[PLUS] button).
ADDITIONAL OPTIONS DESCRIBED Power If your power meter is a hub-based power meter, like a PowerTap, the wheel circumference can be entered here. The default wheel size of 2096mm represents a 700x23 wheel. Ignore circumference if your power meter is not hub-based.
Page 21
This is significant as power is calculated from torque. The PowerTap Auto Zero feature continually adjusts the calibration of your device, compensating, in real time, for environmental factors like temperature, assuring that you have the most accurate power data throughout your ride.
Page 22
Manual Select Manual calibration when another power meter is present on the bike and paired to the Joule GPS. Begin pedaling to see power values from both the RU and the power meter. Once the RU has been clamped against the tire, it is advisable to spend about 2 minutes pedaling to warm up the tire to stabilize the pressures .
Routes allow you to follow a particular predefined path. Routes can be created from previous rides in PowerAgent and uploaded to the Joule. Routes can also be created on one of the many mapping sites on the Internet, imported into PowerAgent and uploaded to the Joule.
Via your favorite mapping website, exported, and uploaded to the Joule GPS. Turn-by-turn Navigation: For those routes that contain turn-by-turn navigation data, the Joule GPS will display upcoming turn information in message notices that appear briefly over the dashboard as each turn approaches.

Not all mapping sites have this capability. TIP: The Joule GPS only allows a route name to display 15-16 characters. Keep this in mind when naming imported routes. NOTE: ridewithgps.com is one of the few websites which exports Turn-by-turn directions in their route files, but only in the TCX format and only if you create the route in ridewithgps.com.

When you have completed the route a notice will appear on the Joule GPS screen containing summary information highlighting the average speed and Route Completion Summary total time to complete the route for both you and the Ride Partner.
WAYPOINTS For the purposes of the Joule GPS, waypoints are single specific locations on Earth. Your home, favorite trail head, or cafe can be a waypoint. The Joule GPS can create, delete, select, and store waypoints. Each waypoint you create is stored on the device.

CHAPTER 5: NAVIGATION COMPASS The Joule GPS contains a magnetic compass. The arrow near the right side of the Title bar on the dashboard points North, regardless of your direction of travel. It is good practice to calibrate the compass upon receipt of the device as well as after each firmware upgrade.
HISTORY OVERVIEW The Ride History area allows access to previous rides and ride summaries stored on the Joule GPS. You can select a full ride, a ride summary, or display a report. Reports compare current ride metrics against averages over a specific time frame (e.g.
Page 33
CHAPTER 6: RIDE HISTORY SUMMARY REPORTS The Joule GPS can create summary reports comparing one of your rides to ride averages over a previous time frame. Report types include summaries of ride data related to Peak Power, Work, Climbing, Time in Zones, and more.
Page 34
REPORTS, Continued There are two additional types of ride history reports: Maximums: Compare maximums from all rides stored on Joule with averages over the selected time frame. • Totals: Compare ride data totals over the selected time period with averages over the same time frame.
Page 35
Rides stored on the Joule GPS can be converted into routes or workouts. The conversion must be done from a full ride file stored on the Joule. There are two types of ride files stored on your Joule GPS: Full Ride files contains all ride data, including GPS and elevation data necessary for conversion to •...
