PAIRING

Download the 4iiii app for iOS or Android to configure your power meter, update firmware and access advanced features. Search for "4iiii" on the Apple App Store or Google Play Store.

Pair with the 4iiii app

4. Select your power meter from the list of available devices. A check mark indicates the device is selected.
5. Press Connect.
   Tip: You can identify your power meter using the ANT+TMID numbers etched onto the side of the pod.

Compatible display units

To view and record power and cadence data from your power meter, pair it with a compatible head unit or smart watch. Compatible devices pair with your power meter using one of the following protocols:

• Bluetooth
• ANT+

Consult the head unit or watch manufacturer for compatibility and pairing instructions.

Pair with a display unit over ANT+

Pairing steps vary between display units. Consult your display unit's user manual for specific instructions.
The following are generic instructions for ANT+ enabled display units:

1. Turn on your display unit.
2. Spin the crank 3-4 times to wake up your power meter.
3. Navigate to the "sensors" menu on your display unit.
4. Add a new sensor.
5. Select only your power meter ANT+ ID from the list of available devices and connect. Tip: Your power meter's ANT+ ID is etched on the side of pod.

Once paired, most display units will remember your power meter and automatically connect when both devices are on.

POWER METER METRICS
Additional power metrics can be added to your display unit's workout screen. Consult the display unit's User manual for instructions. Fields that are available on many display units include:

• Power (1 sec. 3 sec. 10 sec.)
• Normalized Power
• Intensity Factor
• TSS (training stress scores)
• Power Balance (dual power meters only)
• Cadence

ZERO OFFSET

Zero Offset using your display unit

Zero offset (calibrate) your power meter using your display unit before riding. For optimal performance, allow the power meters to adjust to the ambient riding temperature before performing a zero offset. This normally takes just a few minutes.

1. Unclip and dismount from your bike for the zero offset.
2. Spin the crank arms 3-4 times to wake your power meter.
3. Connect your power meter with your display unit.
4. Place your crank arms at 12 and 6 0'clock, with the non-drive side crank arm down. Hold the bike stable and upright.
5. Use your display unit to calibrate your power meter.

1. Navigate to the Zeroing or Calibration menu.
2. Press "Zero" or "Calibrate".
   Tip: If you receive an error message, check that the bike is stable and upright and the cranks are in the correct position before trying again.

Zero offset using the 4iiii app

1. Unclip and dismount from your bike for the zero offset.
2. Spin the crank arms 3-4 times to wake your power meters.
3. From the Devices tab, click the Zero Offset icon below your power meter's name.
4. Place your crank arms in the 12 and 6 0'clock positions, with the non-drive side crank arm downwards. Make sure the bike is stable and upright. Then tap on the crank arm image.

APPLE FIND MY

Setting up you power meter in the Apple Find My app

The Apple Find My network provides an easy, secure way to locate your power meter on a map using the Find My app on your iPhone, iPad, iPod touch, or Mac. Simply pair your compatible product with the Apple Find My app to view it right alongside your Apple devices. The Find My network is encrypted and anonymous, so no one else, not even Apple or the maker of your personal item, can view its location.
Please note that your PRECISION 3+ Powermeter pod will not start sending its location until it has been out of use for 4 minutes. Any rotation of the pod will trigger the gyroscope and switch the pod back from Find My mode to power meter mode.
To use the Apple Find My app to locate this item, the latest version of iOS, iPadOS, or macOS is recommended.

1. Enter PRECISION 3+ Non-Drive Side Pod Into Find My Pairing Mode
   Do this by removing and replacing the battery three times (x3). (Refer to Non-Drive-Side Power Meter battery installation) The pod will then start flashing blue. The pod will remain in this mode for 10 minutes or until the setup is complete. Tip: If it does not start blinking, the pod is already set up in Find My.

2. Open the Apple Find My app on your iPhone, iPad, iPod touch, or Mac and tap on 'ltems' in the bottom banner.
3. Tap on 'Add Item' or the '+'. This screen changes depending on if you have another device already connected to the Apple Find My app or not.
   

4. Then tap on 'Other Supported Item' or 'Add Other Item'
   Again, this screen depends on if you already have another device connected.
   

5. The Apple Find My app will then search for nearby devices
   You should see 4iiii PRECISION 3+ Powermeter popup, click 'connect'.
   Tip: If you have paired your device before this may not pop up - simply reboot your iPhone to clear the cache and try again.
   

6. Next, simply give your power meter a name and emoji and you are all set up!

Serial number lookup

With your hand, firmly double tap the left crank on the side opposite the device to trigger the serial number lookup for the device. In order for this double tap to work, the device must be paired to an iPhone over Bluetooth. This can be done in one of two ways, first by selecting the device in the Find My app with the iPhone to which the device was paired with; or second, with the 'Identified Found Item' button in the Find My app. When double tapped under these conditions, the device will perform a triple green blink, indicating it is in serial number lookup mode.

Disabling Apple Find My

Disabling Apple Find My requires removing the battery by rotating the battery cap counter clockwise 30 degrees. The battery and cap can then be liftted off of the main power meter body disabling the product.

Apple Find My factory reset

1. Wake up the PRECISION 3+ Powermeter by rotating the crank 3-4 times.
2. Choose the device you want to reset and select "Connect" Tip: If you are uncertain about which device to connect to, the ANT+ ID is etched on the side of the power meter for easy viewing.
3. Select your power meter to enter the Device Settings screen and from there select the black settings button.
4. A list of options will come up, choose "Factory Reset Find My", then when prompted, choose "start".
5. To complete the process you will be prompted to remove the battery for 5 seconds and reinstall. The pod will blink green to indicate the factory reset was successful.
   Note: After an Apple Find My factory reset your power meter will automatically be renamed back to its ANT+ ID. You can rename it again to your preferred title by selecting 'rename device' from the Device Settings screen.

MAINTENANCE

Cleaning and storage

• Store your power meters in temperatures no colder than -40C (-40 F) and no warmer than 60C (140 F).
• Use only water and mild soap to clean your crank set. Do not expose the power meter to degreasers, or abrasive or corrosive cleaning agents. Do not pressure wash your power meters.
• Keep water or liquids away from the power meters when the caps are off for maintenance.

Battery life and battery replacements

Your power meter comes with one CR2032 coin cell battery, which allow for up to 800 hours of riding. Replacement CR2032 batteries can be purchased wherever batteries are sold.

1. Twist the cap counterclockwise to remove it. Do not pry the cap.
2. Remove the old battery from the cap by holding the cap by its edges and tapping it against a hard surface.
3. Place the new battery into the cap with the '+' symbol facing the battery cap.
4. Replace the cap and twist it clockwise to secure it.

Batteries must be disposed of properly, including keeping them away from children. Even used batteries may cause injury If ingested!

Tip: Check the condition of the O-ring on the battery cap when replacing your battery. To ensure a watertight seal, keep the O-ring lubricated with silicone grease and replace any o-rings that appear worn or damaged. Replacement battery covers and o-rings are available from our online store.
