1. General information about the POWERCRANK
power meter
POWERCRANK is a device used to measure the pow-
er generated by a cyclist. Data registered and processed
by the POWERCRANK device is made available through
ANT+ and Bluetooth Low Energy protocol. The POWER-
CRANK device is compatible with bicycle computers and
mobile devices supporting ANT+ or Bluetooth Low Ener-
gy protocols (a list of compatible devices is available on
inpeak.pl/en/support_en/).
2. IMPORTANT information for the user
EN
• POWERCRANK device should not be washed with pres-
sure washers that generate high pressure water jet. Di-
recting the water jet to the device can damage it.
• Do not use abrasive detergents to clean the crank with the
POWERCRANK power meter, which may cause damage to
the housing and electronic system.
• The battery life may be shorter at low temperatures than
when the device is operated in conditions that are close to
room temperature.
• Calibration (see point 6) should be carried out relatively
often, especially after changing weather conditions – this
will ensure correct indication of the POWERCRANK power
measurement. Calibration should be carried out each time
after disassembly and assembly of the device on the bike
(screwing to the axis of the crank) and battery replace-
ment.

4. Device assembly/first start/battery
replacement
a. Unscrew the cover in accordance with the arrow placed on
its front (see photo 1).
b. Insert the CR2032 battery into the cover of the POWER-
CRANK device as illustrated on the cover.
c. Make sure the o-ring is in the right place (see photo 2,3).
d. Make sure that dirt (mud, water, dust) does not get into the
battery compartment – if it got, remove it carefully using
a soft cloth or a cotton bud.
e. Insert the cover into the housing so that the red marks on
the housing and the cover coincide (see photo 4).
f. Push the cover into the housing and turn the cover against
the opening direction (see photo 5).
g. Install the left arm in accordance with the manufacturer's
instructions, tightening it with the strength determined
by the manufacturer. Use a torque wrench for this pur-
pose (see photo 6).
h. Mount the pedal.
i. After each assembly of the crank or battery replacement,
calibrate the device according to point 6.
5. Compatibility of the POWERCRANK device with
bicycle computers and other mobile devices
POWERCRANK is compatible with bicycle computers and
mobile devices supporting ANT+ or Bluetooth Low Energy
protocols. A detailed list of compatible devices can be found
on the manufacturer's website inpeak.pl/en/support_en/.

ANT+ pairing
Each POWERCRANK device has its own unique ANT+ num-
ber. The number is placed on the crank arm and on the pack-
aging. The number should be entered in the field intended for
that in the bicycle computer. A description of this procedure
can be found in the bicycle computer manual.
Bluetooth Low Energy pairing
Connection with Bluetooth-equipped mobile devices is
achieved by activating the Bluetooth function, and then
