Joule GPS is compatible with any ANT+TM
power meter, heart rate sensor, cadence
sensor, speed sensor, or combination
speed/cadence sensor.
COMPATIBILITY

CHARGING
The Joule GPS is powered by a high-capacity rechargeable
battery. To charge the battery, plug into a computer or AC wall
adapter (#7060 not included). Typical battery charge lasts
approximately 20 hours of operation.
Should the battery become completely discharged (no partial
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.

About Joule

USER Multiple users can be stored
on each Joule GPS. (e.g. Jim, Bob,
Rachel can all share same device with
unique information). To add another user,
select Add a User, enter the name,
weight, height and date of birth for the
new user. If the training data is known
for this particular user it can be entered
now or enter it later, after a few rides.
CHAPTER 2: JOULE GPS OVERVIEW & SETUP
USER
Because the Joule GPS is multi-user compatible, it's easy to share the device among several riders (e.g.
Rachel, Jim, Bob). Each user can have multiple bikes (e.g. TT bike, Road bike, MTB); each bike can have
multiple sensors associated with it (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+TM signal (e.g. a PowerTap hub, a Heart Rate strap, a remote cadence sensor, a remote speed sensor, etc.).
Sensors can be shared between bikes (e.g. a heart rate strap). Each User can define multiple bikes. Each bike may
have one or more sensors associated with it. Use unique names when creating additional bikes. For example: Jim’s
Racing Bike, Jim’s MTB, My TT Bike, etc.
To add another bike:
· Select “Add a Bike,” enter a unique name and the weight of the bike.
· Associate the sensors with the bike. Make sure all the sensors are awake and
broadcasting (briefly spin PowerTap wheel, wear HR strap).
· Select “Pair All” to pair all awake sensors in broadcast range (PowerTap hub, Heart
Rate strap). Sensors can also be paired individually by selecting it within the
Sensors menu.
Joule GPS User Guide page 10
TIP: The Joule GPS pairs to the sensor(s) closest to the
device first. Hold the Joule within 12” of PowerTap hub
when pairing in the presence of other sensors.

Intervals are useful for viewing ride data specific to a section of a ride, such as a hill or other period of high intensity
riding. The Interval Summary dashboard contains a summary of each interval completed up to that point in the ride.
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. Holding the [INTERVAL] button down for 2 seconds toggles between the 2 views.

CHAPTER 3: DASHBOARDS
INTERVALS continued
When using intervals, the Joule GPS can operate in one of two modes: Lap Mode or Interval Mode. These modes refer
to the action taken when the [INTERVAL] button is pressed. The default is Lap Mode. The mode can be changed in the
Record Control section of the Device menu (see chapter 8).
• Lap Mode refers to the traditional way the interval button has operated on all computers from PowerTap: Pressing
the [INTERVAL] button completes one interval (or Lap) and begins the next interval (Lap). Interval 0 (zero), or Lap 0,
is the time recorded from the start of the ride to the first [INTERVAL] button press. The next button press completes
Lap 1 and begins Lap 2. The next button press completes Lap 2 and begins Lap 3, and so on...
• Interval Mode refers to tracking a rider’s intervals as opposed to laps. When the Joule GPS is set to record in
Interval Mode, the first press of the [INTERVAL] button begins interval 1. The next press of the button ends interval
one. The next press of the button begins interval 2. The next press of the button ends interval 2, and so on... The
period between intervals is referred to as the “rest” period in the Joule title bar but the rest/recovery period is not
listed on the Interval dashboard. Only intervals are listed on the Interval dashboard.

The Navigation dashboard displays the path ridden from the start of the ride to your current position.
Additionally, the screen displays two configurable metric windows, interval markers (), waypoints (), and a
pacing icon (), depending upon which navigation feature is being used. This Dashboard is also used when
navigating to a Waypoint or following a route.
• Zoom the map in/out by pressing the PLUS (+) and MINUS (-) buttons.
• Zoom levels range from 75 meters to 80 kilometers (250 ft to 50 miles).
• When following a route, information related to total route distance or distance to the next turn appears
above the metrics. The route name will appear briefly in this area.

See Appendix D for detailed information on GPS signals.

CHAPTER 4: SENSORS
SENSOR OVERVIEW
The Sensor section of the Main Menu is the gateway to all bicycle and sensor associations. In this area you can:
• Define and pair various sensors (e.g. power meter, heart rate strap, speed, cadence, PowerCal, PowerBeam, etc.).
• Create a “bike” description by associating a specific group of sensors.
• Or, if you have already created a bike or two, you can select which bike description you are about to ride or “use,”
or which bike description to “edit.”
• Here, you can also access utilities related to calibration, such as calibrating the torque of a particular power meter
or calibrating the Resistance Unit (RU) of a PowerBeam indoor trainer.

OPTION DESCRIPTION
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). Selecting No will instruct the Joule GPS to continue to scan for additional sensors of
the same type before searching for sensors of another type (by pressing the -[MINUS] button).
To pair sensors individually, scroll to and select the sensor. A menu of sensor names will appear. Select
“<new sensor>” to scan for an awake and present sensor. When a sensor of same type is found, the ID is displayed.
Selecting Yes will link the sensor with the defined bike. Selecting No wil instruct the Joule will continue to scan for
another sensor of the same type. The name “<none>” indicates no sensor has been linked to the defined bike.
Scroll to and select the sensor name. A menu of sensor names will appear. Scroll to the preferred predefined
sensor; select it. You will be asked to Use it or Edit it. Selecting “Use” will link the sensor to the bike definition.

SENSOR ADDITIONAL OPTIONS DESCRIBED
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.
Auto Zero and Manual Zero options refer to calibration and are discussed in the following pages.
The PowerCal option is set automatically, during the paring process, when the Joule GPS determines that the present
