Water resistance notice
The Stages™ power meter is designed to provide excellent water resistance
and tested to resist water ingress to the IPX7 standard (up to 1 meter). This
provides outstanding water resistance for cycling conditions on-road and o,
including stream crossing and heavy rain. Please keep in mind this is an
electronic device not a submarine; as such, there are limits to the water
resistance.
Do not subject the power meter to direct spray from a high pressure
sprayer. Water exiting a sprayer can reach hundreds and sometimes
thousands of pounds of pressure per square inch. This may be equivalent
to the pressure found at ocean depths of 1000 feet or more! It is possible
for water to be forced past the o-ring seal under these conditions and
damage to the electronics may occur.
Battery installation or replacement
1. The power meter uses a CR2032 battery that can be installed or replaced
by hand without the need for additional tools.
2. Referencing FIG 1 and 2; rotate the battery cover in the counter clockwise
direction to release the cover.
Do not attempt to use any tools to force or pry the battery door open.
3. Place the new CR2032 battery into the battery receptacle with the “+” side
facing out. It is critical that the battery is inserted in this orientation.
4. Before installing the battery cover take care to ensure the water seal o-ring
is seated properly in its groove as illustrated in FIG 4.
5. Replace the battery door as illustrated in FIG 5.
6. Once the battery door has been properly inserted and is even with the
surface of the power meter, use your nger to rmly rotate the door back
to the locked position as illustrated in FIG 6.
The power meter ships without a battery installed.
The battery must be installed before rst use.
Power meter (crank arm) installation
IMPORTANT NOTICE: to ensure power meter compatibility with the
frame and components, please follow these steps carefully and in the
specic order. Do not install the pedals until compatibility of the power
meter has been conrmed.
1. Attach the left crank arm to the bike following the instructions provided
by the crank arm manufacturer and supplied with your power meter.
Links to crank manufacturer's installation instructions may be found at
the Stages Cycling website:
http://www.stagescycling.com/support-general-instruction
2. Carefully and fully install the crank arm onto the bike but
DO NOT ATTACH THE PEDAL AT THIS TIME.
3. Carefully and slowly rotate the crank 1 full revolution to ensure there
is no contact between the power meter sensor housing and any part
of the frame or other components as illustrated in FIG 7.
4. If there is interference between the power meter and the frame or other
components, contact your retailer for technical assistance.
Contact Stages Cycling If the power meter was purchased from our online
store.
5. If no interference is found you may continue with the nal installation of
pedals according to the pedal manufacturer’s instructions.
Power meter wireless communication
The power meter is compatible with a wide range of display devices that utilize
the ANT+ or Bluetooth Smart (4.0) wireless communication systems. Many
leading brands of bicycle computers utilize the ANT+ “prole” for power
measurement and can be used to display the power (Watts) and cadence (RPM)
measured by the power meter and sent wirelessly to the computer. Bluetooth
Smart is a popular wireless communication system included with many of the
latest mobile phones. Utilizing Bluetooth Smart, a mobile phone running a
compatible App can be used to display the power (Watts) and cadence (RPM)
data within the App.
8 9
Pairing the power meter
The power meter must be connected or “paired” to the cycle computer or
mobile device (collectively referred to as display units) according to the display
manufacturer’s instructions. Each power meter has a unique ANT+ device ID
and a unique Bluetooth ID. During the pairing process the applicable device ID
is recorded by the display and will be used to communicate with the
corresponding power meter. The ANT+ ID number is printed on the back of
the power meter and also supplied with the documentation. The Bluetooth ID
is recognized and displayed by the Bluetooth device during the pairing
process. Once paired to the power meter, ride data (Watts and RPM) will be
transmitted from the power meter to the display unit. Other important
functions such as resetting the power meter’s zero oset will also be enabled
through the display unit. Both the ANT+ and Bluetooth IDs are
permanently assigned to the power meter and are not aected by
changing the power meter battery.
ANT+: Ensure the power meter has a fully charged CR2032 battery properly
installed. Rotate the crank arm one time to ensure the power meter is awake
and ready to communicate. Follow the ANT+ device manufacturer’s
instructions for pairing a power meter to the display unit. The procedures may
vary between manufacturers.
Bluetooth Smart: Ensure the power meter has a fully charged CR2032 battery
properly installed. Rotate the crank arm one time to ensure the power meter is
awake and ready to communicate. Follow the Bluetooth Smart Ready (4.0)
device manufacturer’s instructions for pairing a power meter to the display
unit. The procedures may vary between manufacturers.
Zero oset calibration
The zero oset calibration is an important feature of the power meter that
resets the zero oset value for the power meter sensors. There are physical and
environmental conditions that may aect the zero oset value and there are
methods both manual and automatic that will adjust this value to
accommodate for the changing physical and environmental condition. The
zero oset of the power meter is essentially the sensor reading or values
measured when the power meter has no pedaling load (torque) applied. The
act of calibrating the zero oset causes the power meter to measure the value
at zero load and then records this value as the baseline for power
measurement. Loads applied while pedaling will then be measured as torque
and used by the sensor to determine power in Watts. The zero oset value can
be aected by the installation of the crank arm and the tightening of the
securing hardware. The torque applied to the securing hardware can impart
some strain into the crank material that is easily accounted for by manually
calibrating the zero oset. Any time the power meter is removed from the bike
and reinstalled the zero oset should be calibrated.
Ambient temperature shifts can also aect the zero oset to some extent. To
ensure maximum accuracy it is advisable to manually calibrate the zero oset
before each ride. The power meter utilizes automatic temperature sensors to
compensate for temperature changes that take place during the ride. This is
done automatically while you ride and you need not take any further steps to
calibrate the sensor during the ride.
How to calibrate the zero oset
Calibrating the zero oset is a function controlled by the cycle computer or
mobile device (display units) paired to the power meter. Please note that some
device manufacturers refer to the step of resetting the zero oset as
“calibration”. When paired to a compatible ANT+ cycle computer or Bluetooth
Smart mobile device, the power meter and display units are in two-way
communication. The display unit can send a command to the power meter to
calibrate the zero oset value and in some cases the resulting zero oset value
will be sent back from the power meter to the display unit and be shown on the
screen. Please note the displayed zero oset value will NOT be zero but rather
a number that corresponds to the measurement taken by the sensor.The
display units will also indicate if the procedure was successful or failed.
10 11
Before attempting to calibrate the zero oset value of the power meter,
ensure that a working battery is in use. Rotate the power meter one revolution to ensure the power meter is awake and ready to communicate.
The left crank arm with power meter MUST be positioned straight down (6
o’clock position) and ensure there is no load on the pedals and the bike is
stable. See FIG 8 for a visual reference. If the left crank arm is not straight
down the reset procedure for zero oset will fail.
Although the process for calibrating the zero oset will vary depending on
the display manufacturer, it should roughly follow these general steps;
however, consult your display unit’s manual for specic steps:
1. Ensure the power meter has been paired to and is communicating with
the display unit.
2. Position the crank straight down (6 o’clock position) FG 8, and the bike is
stable.
Note: please see error code #32 in the troubleshooting section below.
The power meter sensor will determine if the crank is positioned in an
acceptable orientation during the zero reset process.
3. Access the settings function of the wireless display.
4. Select the power sensor (many times the power sensor is located within a
“BIKE” setting).
5. Select the “CALIBRATE” or “Zero” function.
6. Calibration of the zero oset will begin and take only a few seconds to
complete.
7. Upon completion the display will show a message indicating success or
failure of the procedure.
Troubleshooting
Calibration time out
When using a Garmin® display unit with the heart rate (HR) sensor enabled, it
is possible the calibration process will take too long and time out before
completion. To resolve this either turn o the HR sensor on your Garmin while
you calibrate your power meter (you can turn it back on once the power
meter is calibrated) or put the HR strap on and ensure it has been detected by
the display before you attempt to calibrate the zero oset.
If no power (watts) or cadence (RPM) signal is being received by your
compatible display unit when riding the bike, please conrm the following
items:
1. Conrm that a working CR2032 battery is properly installed in the
power meter according to the reference FIGs 1-6 of this manual.
2. Ride the bike with a pedaling cadence of greater than 30 RPM. Your
Stages Power meter will not send cadence or wattage to the display
unless a true pedaling force is applied. If you pedal your bicycle in the
work stand the display will not show cadence or watts — this is not a
problem — as soon as you ride the bike you will see your
cadence and power values displayed.
3. Ensure that the power meter has been successfully paired to the display
unit being used according the manufacturer’s specic instructions.

Maintenance and cleaning
The only items of the power meter that can be serviced by the owner are the
battery, battery cover and o-ring. No other items are serviceable and no
attempt should be made to adjust or alter any other items.
The power meter uses a custom 0-ring and is lubricated to with o-ring grease.
The grease protects the 0-ring from abrasions and environmental conditions
and is critical to ensure proper water resistance. When servicing the o-ring
ensure it is well coated with a grease designed for use on o-rings which may
be obtained at most hardware stores.
When cleaning the power meter use only water dampened cloth to wipe o
dirt and debris. Never use any harsh cleaning chemicals that may damage
the plastic housing. Inspect the battery compartment to ensure the batter
contact is clean of any corrosion.
Never directly spray the power meter or battery door with high
pressure water. The water pressure from sprayers can reach thousands
of pounds per square inch and may force water past the o-ring
damaging the power meter electronics.
