The NODE computer has two modes:

Ride Setting

Ride This is the mode you will use when riding your bike. Ride mode (Figure 3) displays the functions, the information gathered by the computer. This information can be the current data (your current speed, the current temperature, or data from other functions), or for some functions the NODE can display your average, total, or minimum/maximum data. You can learn more about each of these functions in the section that covers functions. Setting This is the mode you will use to prepare your computer for your first ride, or to set more advanced features. Setting mode (Figure 4) allows you to program the computer, allowing you to choose the units you prefer (e.g. miles or kilometers), input the correct time or altitude, or set alarms to alert you when you exceed your chosen minimum or maximum heart rate. If the computer is left in Setting mode, it automatically returns to the Ride mode.

Figure 5. Changing Modes.

Sensors

The NODE can compute information from four sensors:
Cadence Speed Heart Rate Power
Not all NODE computers are packaged with all the sensors. If your bicycle is appropriately equipped, you can purchase a combination speed/cadence sensor. You can also customize your computer by purchasing additional Bontrager NODE sensors or a power sensing system of your choice from your Bontrager dealer.

Functions of Sensors

Sensors sense impulses, either from the passing of magnets that are attached to a spoke or a crankarm, electrical impulses generated by the pumping of your heart, or the impulses from a power meter. When the sensor senses input, it sends a radio signal to the NODE computer. This signal has a range of about 5 feet (1.5 meters).

Sensors Require Power

Sensors require electrical power. Each sensor gets its own power from an individual battery. If the battery loses power, the sensor will no longer send signals to the computer.

Before Your First Ride

Pairing (Pair) Procedure
Before the NODE can display any data, it must identify each radio signal sent by the sensors (Figure 6). This process, which takes about one minute, is called Pairing (Pair). After the NODE creates a Pair, it remembers the signals, so normally this only occurs once (during the initial set up). Sensors only send signals when they are activated: The wheel must turn to activate the speed sensor The crankarm must rotate to activate the cadence sensor or the power sensor You must wear the chest strap to activate the heart rate sensor During the Pairing procedure, the 0 of the speed display flashes. This procedure can take up to 60 seconds. When it is complete, the icons for successfully connected sensors display at the bottom of the screen. If an icon for a sensor disappears, a pair was not created for that sensor.

The NODE only needs to perform the pair procedure once. If the Pair fails, or later you add another sensor, you can also force the Pairing procedure: In Ride mode, hold and for three seconds while you make the sensors send signals.
Figure 6. Locking onto Radio Signals from Sensors.

Force Pair

Connecting (Connect) Procedure
Each time you switch on the NODE, it automatically tries to Connect (lock on) to the signals it remembers from the Pairing procedure. Just like during Pairing, for the NODE to Connect to signals you must activate the sensors (make them send a signal). During the Connecting procedure, the 0 of the speed display ashes. After the Speed sensor connects, the 0 stops flashing but the icons of the other paired sensors continue to flash until the Connecting procedure is complete. This can take up to 60 seconds. When it is complete, the icons for successfully connected sensors display at the bottom of the screen (Figure 7).

Force Connect

If the Connecting procedure fails, the appears on the screen in each function where the sensor is switched to ON but the Connecting procedure failed. In addition, the icon for that sensor will disappear. These indications happen when the NODE does not receive a signal during the Connecting procedure. You can force the Connecting procedure: In Ride mode, hold signals. for three seconds while you make the sensors send

3. To calibrate, press

As the NODE calibrates, the 0 (zero) of speed flashes each segment in a circular pattern. Then DONE (done) appears, and after one second the NODE returns to the PWR function.
If CALIB? appears, the NODE returns to the calibration screen because the calibration procedure failed. Repeat steps 2 and 3, or see Troubleshooting.
4. To return to PWR, press

HEART RATE (HR)

Heart rate is a measurement of the number of times your heart beats in a minute.
Features of Heart Rate Function
If heart rate data is sent to the NODE, the lower section of the screen displays HR (Figure 13). The NODE can display Current (CUR), Average (AVG), and Maximum (MAX) heart rate. You can also set fives zones. Each zone is a target heart rate within an upper and lower limit. The NODE computes the amount of time you have spent in each zone.
Heart Rate Sensor The sensor for heart rate is the NODE chest strap. The chest strap must be correctly located on your chest (Figure 14), against your skin, and will work better if the contact area is slightly moist. The chest strap needs to be snug to stay in place. Slide the buckles to adjust the length of the strap. The sensor must be switched to ON and send a signal.

INTERVALS (INT)
Intervals are periods of time of a set length, separated by set periods of time.

Interval Clock

The interval clock runs separately from the Time function, so you can still use the stopwatch function and scroll through standard functions without stopping the interval clock. In the INT screen, there are two clocks above a box (Figure 16). When the clock on the left is running, it counts down the time that remains in the interval. When the clock on the right is running, it counts down the time that remains in the rest. The box gives the number of intervals that remain of the total repetitions, and a bar moves across the box to show the relative progress of the interval and rest clocks.

Battery Maintenance
There is a battery in the computer, and also in each of the sensors. If you use the NODE for one hour every day, the batteries should last about 10 months. To extend battery life during long periods of non-use, remove computer from bracket to deactivate the Auto Start feature.
You can erase all settings and programming. Push the Reset button (Figure 36). The NODE goes to the procedure for Automatic Setup.

Sensor Batteries

Replace the batteries in the sensors every 10 months, or whenever the computer cannot perform the Pair or Connect procedure with a given sensor (Figure 34).

Computer Battery

Replace the battery in the computer when the battery indicator gets to 10% (when the indicator shows no bars). Before removing the computer battery, note the Trip and Total values. When the battery is removed, the computer automatically does a Reset (erase settings) and changes function totals to zero (0). After installing a new battery (Figure 35), you can manually set your totals.

Battery Type

The same battery type is used for the computer and each sensor, a 3-volt CR2032 lithium cell. When you go to the store, take the old battery with you.
