In the Registration screen enter your first name, last name, and email address and press Register. Once you have registered your POWERBEAT the Crank Details screen appears.
9 Step 5: Entering crank details and body weight When the Crank Details screen appears, enter the following information in this order: Step 6: Removing the Left and Right Pedals Removing the Left Pedal 1. Crank manufacturer 2. Crank model 3. Crank size (printed on the inside of the crank) 4. Your body weight Press Next to display the Removing Pedals screen. Tools: Allen key or ratcheting wrench 1. With the left crank arm pointing downwards towards the floor, insert the appropriate Allen key or ratcheting wrench into the back side of the pedal spindle, holding the pedal down so it doesn’t spin. 2. Turn the Allen key in a clockwise direction until the pedal comes off.
10 Removing the Right Pedal 1. With the right crank arm pointing downwards towards the floor, remove the right pedal in the same way, but turning the Allen key in a counter-clockwise direction. 2. Put the two pedals aside until tomorrow, when you will reattach them. 3. Press Next. Step 7: Gluing the Left and Right Sensors Note: The sensors have no right or left side, so you can glue either sensor to either crank arm. To glue the two sensors you will need the following: Once you have glued the sensors, you will need to wait 24 hours for the glue to dry. Included with your PowerBeat:  2 sensors  1 gluing tool  2 refillable water bags  1 charger with cable  2 adhesive rubber strips  4 washers  4 alcohol pads  1 primer pad (To be used only if your crank is aluminum. Do not use on a carbon crank.)  Sandpaper  Tube of glue (Shake before using.)  Tube of glue remover (Shake before using.)  Pair of protective rubber gloves Not included with your PowerBeat:  Pencil  Bucket of water, dishwashing liquid and a sponge  Paper towel
11 Three Rules for Situating the Sensor in the Perfect Position Crank arms come in many different designs and shapes. Before gluing the sensors in place, you will need to determine the proper location, so that when you use the Gluing Tool, you will know where to attach the sensors. Strive for maximum surface area and fill any gaps with glue. 3 Simple Important Rules Rule 1: With the crank arm pointing to the rear of the bike, the sensor should be glued on the topside.
12 The Gluing Tool The gluing tool is used to position the sensor on the crank arm, so it is glued in the proper location. Cleaning the Crank Arms 1. Clean both crank arms thoroughly with the sponge dipped in diluted dishwashing liquid, to remove any dirt and oil residues. Wipe with paper towel and wait until completely dry. 2. On the left side of the bike, turn the crank so the left crank arm is facing the rear wheel, parallel to the floor at a three o’clock position. Bolt A goes into the pedal hole Bolt B is used for fixing the location. Bolt C has a moveable, transparent sensor compartment, with two lines that mark both ends of the sensor. Rule 2: When glued, the sensor should be aligned straight in the center. Rule 3: The silver side of the sensor should have full contact with the surface of the crank arm when glued. Any gaps should be filled in with glue.
13 3. Wipe the top side of the crank arm with one of the alcohol pads. 4. Wait a moment for the alcohol to evaporate by itself. (Don’t be tempted to blow on it!) 5. On the right side of the bike, turn the crank so the right crank arm is facing the rear wheel, parallel to the floor at a three o’clock position. 6. Wipe the top side of the crank arm with the second alcohol pad. 7. Wait the alcohol to evaporate by itself. 8. Put on the protective rubber gloves and keep them on until both sensors have been glued to the crank arm. 9. If your crank arm is carbon, do not apply primer! Continue to the next section, Attaching the Gluing Tool. If your crank arm is aluminum, turn the left crank arm towards the rear wheel and wipe the primer pad once along the top part of the crank arm. Turn the right crank arm towards the rear wheel and wipe the same primer pad once along the top part of the crank arm. 10. Let the primer undercoat cry for 10 minutes before proceeding with the gluing. Attaching the Gluing Tool 1. Turn the crank so the left crank arm is facing the rear wheel, parallel to the floor at a three o’clock position. 2. Attach the gluing tool by plugging Bolt A firmly into the pedal hole, making sure the gluing tool is aligned with the crank arm and fits tightly against it. 3. Loosen Bolt B and use Bolt C to find the exact place for the sensor, according to the 3 rules. Bolt C has a transparent sensor compartment with blue lines to indicate exactly where the sensor will be once it is glued. 4. Use the adjustable ball joint to find the right spot on the crank arm. 5. Once you have the proper location, tighten Bolt B counter-clockwise, until the location is securely fixed, that is, aligned in the center with as much contact as possible. 6. Move the Gluing Tool up and down several times, to make sure the sensor compartment falls back into the appropriate place each time. If you detect any displacement, repeat the steps, rather than taking any chances once the glue is applied.
14 Gluing the Sensors Preparing the left sensor for gluing 1. Place the sandpaper on a flat surface. 2. With the silver side facing down, scrape one of the sensors (they are identical) gently on the sandpaper for about 5 seconds, pressing with two fingers, and being careful not to bend it or to apply too much pressure, until you notice scratch marks on the silver. 3. Gently place the sensors inside the sensor compartment of the Gluing Tool, with the plug facing the direction of the front wheel. 4. Check one last time to make sure the sensor falls into the proper location, according to the 3 rules. 5. Gently rub one alcohol pad on the silver side of the sensor and another alcohol pad on the spot it will be glued to, in order to remove any dirt and oil. Wait about two minutes, for the alcohol to dry by itself (without blowing on it). 1. Shake the tube of glue and carefully spread a thin layer of glue over the entire surface of the sensor, making sure the cable is not in the way. 2. Place the sensor compartment on top of the crank arm in the proper location. 3. Press gently on both ends of the sensor, using two fingers, for about 30 seconds, for the glue to dry. 4. Release your fingers and let the glue dry for another 5 minutes. 5. Carefully detach the sensor from its compartment and disengage the Gluing Tool. 6. If the sensor is not fully in contact with the surface of the crank arm (for example if the crank arm is curved) fill in any gaps with glue. 7. Press Next.
15 Gluing the left sensor: 1. Preparing the right sensor for gluing 2. Prepare the right sensor for gluing in the same manner as you prepared the left sensor. Gluing the right sensor Step 8: Installing the Left and Right Comp Units Tools 1. Shake the tube of glue and on the right side of the bike, with the crank arm facing the rear wheel, in the 9 o’clock position, glue the second sensor on the right crank arm, following the instructions for gluing the left sensor, then remove the protective rubber gloves. 2. Press Next. 3. Wait 24 hours for the glue to dry completely before continuing the installation. 4. In the meantime charge the comp units so they will be ready for completion of installation and calibration tomorrow.  4 washers  2 rubber adhesive strips  2 comp units  Allen key / ratcheting wrench
16 Installing the Left Comp Unit 1. Turn the left crank arm until it faces the front wheel, in the 9 o’clock position. 2. Figure out how many washers or spacers you need: Feel the space where the thread of the pedal begins and the external smooth surface of the crank arm. The actual gap determines how many washers you need to use. 3. Put a washer in the space and if there is still room, add the second washer, until it sticks out just a little bit over the surface of the crank arm. (Note that some types of crank arms may not need any washers.) 4. Place the comp unit marked Left on the spindle thread, then add the appropriate number of washers. 5. Screw in the pedal, with the socket of the comp unit plug facing the sensor. 6. Using the Allen key or wrench, tighten the pedal back in place, making sure the comp unit is aligned with the crank arm, but not actually touching it. 7. Press Next. Installing the Right Comp Unit 1. With the right crank arm facing the front wheel in the 3’oclock position, using the comp unit marked Right, install the Right comp unit, following the instructions for installing the left comp unit. 2. Press Next.
17 Connecting the Sensors to the Comp Units Connect the sensor plugs to the comp unit. Use the adhesive rubber strips to secure the cables to the crank arms. Make sure your phone has Bluetooth turned on. Turn the crank 3 times until the following screen appears.
18 If the sensors are not connected the following screen appears. Press Try Again and keep turning the crank until the Installing the Comp Units screen appears. (Or, if you haven’t yet scanned the QR code, see Manual Scan at the end of this section.) Once the app has detected the sensors, the Units Found screen appears. Check the two units and press Next. The app notifies you that your PowerBeat was successfully activated. With you bike still on the trainer, get on and ride for a moment or two. You are now ready to calibrate your POWERBEAT. Follow the instructions on the application.
19 Manual Scan 1. Press Manual Scan to scan the QR code. 2. Select New Devices. 3. When asked “Do you want the selected devices to be your permanent devices?” select Yes. The Status screen appears. Step 9: Zero Offset Calibration Before calibrating your POWERBEAT, you need to perform zero offset calibration. We recommend that you watch the movie in the app before performing zero offset calibration for the first time. We also recommend that you also calibrate the zero offset, using your head unit, every time you go for a ride. Zero offset calibration resets the zero offset value of the POWERBEAT sensors when no torque is applied. This is then used as a baseline for power measurement, to receive an accurate power reading. It only takes seconds to perform zero offset calibration. To calibrate the zero offset: 1. Hold your bike upright and make sure nothing is touching the pedals. 2. If you are calibrating the zero offset via the head unit, follow the instructions for your head unit, otherwise continue. 3. Make sure both POWERBEAT sensors are connected to the comp units. If you have been riding, you need to unplug them and plug them back in. 4. Press Set Zero. 5. When zero calibration has been completed the app responds with “Zero calibration was successful!” 6. Press Next and the Calibration screen appears. Step 10: Calibration POWERBEAT calibration is performed through the application. You should only need to calibrate once, when you first install your POWERBEAT. But keep the 2 water bags and 2 hooks in case you ever need to recalibrate.
20 Tools For proper calibration it is important that your bike remains steady at all times. You can stand it upside down on the floor or suspended from a stable work stand. Preparing the Water Bags (Weights)  2 hooks  2 water bags (Before starting calibration, fill the two bags with water.) 1. Uncap one of the bags and fill it completely full of tap water. 2. Jiggle and tilt it, to make sure there are no remaining air pockets, fill it to full capacity, and then cap it. 3. Fill and cap the second bag in the same way. 4. Attach the plastic handles to the two water bags, by sliding each handle through the loop and pressing the ends together until you hear a clicking sound. 5. When it is stable, the Calibrate button becomes active on the app. 6. Press Calibrate.
21 Calibrating the left and right crank 1. Turn the left pedal down to the 6 o’clock position. 2. Using one of the hooks, hang one of the water bags on the left pedal and let it stabilize in the 6 o’clock position. The crank arm must be horizontal, that is, parallel to the floor. Make sure the bag is not touching any part of the bike and that it is stable. 3. When it is stable, the Calibrate button becomes active on the app. 4. Press Calibrate 5. Remove the water bag from the left pedal. 6. Turn the right pedal down to the 6 o’clock position. 7. Hang the water bag on the right pedal and let it stabilize in the 6 o’clock position.

24 Step 11: Pairing your POWERBEAT with your Head Unit Once you have finished installing your POWERBEAT, you can pair it with your head unit. Carefully read your head unit’s user manual for a description of the pairing process, as head units differ. POWERBEAT is compatible with any head unit that works with (e.g. GARMIN edge 500 or Suunto Ambit 2). POWERBEAT also supports two modes of , in order to be compatible with most head units that are available on the market today: Single power sensor channel  BLE: e.g. Suunto Ambit 3 or Cateye Padrone smart)  In Single Channel mode the right PowerBeat calculates and transmits the total power to the head unit . Dual power sensor channel  Dual: e.g. Polar V800 and V650 or Channel POWERBEAT mobile App  In Dual Channel mode right and left leg power data are transmitted independently to the head unit, which then calculates the total power.
25 Pairing your POWERBEAT with an Head Unit 1. With the device properly installed and connected, select the ANT+ communication method in the POWERBEAT app. 2. Make sure POWERBEAT is turned on, by spinning the crank arms several times. 3. Turn on your head unit and perform a Device Search or alternatively enter the PowerBeat ANT+ ID number in your head unit (following your head unit’s pairing instructions.) 4. Make sure the displayed ANT+ ID is identical to your POWERBEAT ID, which is located on the comp units, as well as inside the box.
26 Pairing your POWERBEAT with a Head Unit To pair your POWERBEAT with a head unit: 1. Check your head unit’s user guide, to find out which mode is supported. If your head unit allows the pairing of two power meters (left and right), use Dual Channel mode, otherwise use Single Channel mode. 2. Make sure both POWERBEAT sensors are connected to the comp units. If you have been riding, you need to unplug them and plug them back in. (standby mode can also be reached by waiting for a few minutes. 3. Select (Bluetooth Smart)1 in the POWERBEAT app. 4. Unplug your left comp unit. 5.

29 Important Safety Information POWERBEAT uses LiPO rechargeable batteries. WARNING: Maximum ambient temperature for charging mode is 109.4 degrees F (43 degrees C) and for discharging mode 122 degrees F (50 degrees C.) Do not send the comp unit in the cargo of a plane, because the low temperature may permanently damage the LiPO battery. POWERBEAT is durable enough to sustain even harsh weather conditions. It has a built-in temperature compensation mechanism, so the power figures remain consistent regardless of the weather. But never leave the comp unit in an unattended vehicle, as extreme heat may damage it. Do not damage, disassemble, or modify the POWERBEAT in any way. Before washing your bike, either remove the comp units or make sure they are plugged into the sensor. Never wash the bike if the comp units are unplugged from the sensors. Make sure the pedals are securely fastened, in accordance with the pedal manufacturer’s instructions. Do not rotate the pedals if either or both of the comp units are unplugged, as they may get caught in the bike’s mechanism and become damaged. Do not connect a power source to the charger if the charger or comp unit appears to be damaged.
30 Troubleshooting Power and cadence readings are zero, erratic, or inaccurate First check that the balance readings are correct. If they show just 50%-50% while riding, then make sure that the batteries are fully charged and that the sensor plug is well connected to the comp unit. If the readings are still erratic, calibrate or zero offset the device again using the app. Make sure not to touch the crank while calibrating. No data is coming from POWERBEAT, although everything else works well. 1. Make sure the POWERBEAT is on. If you are not sure, spin your crank arms several times. 2. Disconnect the sensor plugs from the comp units, wait several seconds, and reconnect them. Then turn POWERBEAT on by spinning the crank arm and check again. 3. Recharge the comp units. My head unit doesn’t have the functionality to notify me when the batteries are getting low. Check the battery level in the PowerBeat mobile application on main riding screen. Maintenance PowerBeat is an electronic device that requires proper maintenance. Maintenance consists mainly of the following four actions: 1. Mobile App updates. We recommend that you upgrade your app whenever a new update is released. 2. Firmware updates, when released. 3. Zero Offset calibration 4. Recharging Mobile App Updates Watteam recommends that you automatically update your PowerBeat mobile application whenever an update is released through the mobile app store (Google Play or Apple Store.)
31 Firmware Updates Once you have downloaded the WATTEAM POWERBEAT application and registered your POWERBEAT, you will receive an email notification whenever a new firmware release is available.
