2.2 Preparing for your ride
Your powermeter is delivered with a pre-installed battery and comes ready to ride.
1. Spin the crank arms four times to wake your powermeter.
2. Pair your powermeter with a compatible display unit using ANT+ and/or
Bluetooth Smart. For more details, see Section 3
3. Perform a zero offset (some display units refer to this as calibration). For more
details, see Section 4
Quick Tip: For best performance, remember to perform a zero offset before each ride.

2.3 Installing and replacing batteries
Your powermeter uses common CR2032 coin cell lithium ion batteries. If the battery
reaches 0% on one side, the other side of the dual system will automatically operate
as a single-sided powermeter; reported wattage from this side will be doubled.
When the reported battery life is 8%, you will have 8-10 hours of remaining usage.
Non-drive-side crank arm replacement instructions are in Section 2.3.1
Drive-side Dura-Ace FC-9000 replacement instructions are in Section 2.3.2
Drive-side FC-Mxxxx (XT/XTR series) replacement instructions are in Section 2.3.3
Quick Tip: When storing your batteries, keep them separated; shorting a battery
will shorten its life.

2.4 Configuring your powermeter using the 4iiii App
When your PRECISION PRO was shipped from the factory, the drive-side and
non-drive-side powermeters were linked together such that they operate as a
dual-sided powermeter. Your powermeter can also operate as two independent
single-sided powermeters. If you want to operate your PRECISION PRO powermeter
as a single-sided powermeter using only one crank arm, follow the instructions
on Section 2.4.2
Additional information and settings on your PRECISION PRO can be accessed
through the 4iiii app on iOS and Android devices using Bluetooth Smart.
To configure your PRECISION PRO powermeter in single-sided mode, follow the
instructions in Section 2.4.3
To configure your PRECISION PRO powermeter in dual-sided mode, follow the
instructions in Section 2.4.1
Quick Tip: Pairing is the connection between your powermeter and display units
such as a bike computer, watch, or smartphone. Linking is the connection between
the drive and non-drive side powermeters.
Quick Tip: Connect your powermeter to the 4iiii App once a month to check for the
latest firmware update. If your firmware requires updating, you will be prompted
to upgrade.

4.1 Performing a zero offset via ANT+
For best performance, you should allow the powermeter
to adjust to the ambient riding temperature before
performing a zero offset and starting your ride. Allowing
your powermeter to reach ambient temperatures
normally takes a few minutes.
To perform a zero offset on your powermeter using your
ANT+ display unit, follow these steps:
1. Unclip and dismount from your bike
2. Spin the crank arms four times to wake your
powermeter
3. Place your crank arms in the 12 and 6 o’clock
positions
4. Use your display unit to calibrate your powermeter
i. Go to the Sensors menu
ii. Select the ANT+ ID of your powermeter
from the list of available sensors
iii. Choose Calibrate
Quick Tip: Some display units uses the term “calibration”
rather than “zero offset”.
