User Manual

6. Close and screw the battery compartment again. Make sure everything is clean and the two

O-rings are seated correctly.

CAUTION! If you want to mount power2max powermeter with a 130 mm BCD aero chainring,

you must shorten the chain catcher at the battery cover by 1 ... 2 mm to avoid its collision

with the chainring. Then, the distance between chainring and chain catcher in mounting po-

sition should be about 1 mm. For shortening by grinding, we recommend the use of abrasive

paper.

7. The start-up procedure for the

power2max powermeter is

now completed.

You can start off!

4. Insert the supplied RENATA CR2450 battery. Pay attention to the correct polarity. The POSITIVE

pole (face of battery) must be visible after the battery has been inserted.

5. The battery compartment accommodates two LEDs

for function checks enabling you to easily check the

operability and start the system quickly and hassle-

free.

After the battery has been inserted, the powermeter

signals readiness for service by a short flashing in se-

conds of the green LED for about 20 seconds.

During this period, the

power2max powermeter starts

emitting radio signals that can be received by an

ANT+ capable bike computer.

Now, start the teach-in mode to adjust the

power2max powermeter to your ANT+ capable

bike computer. Observe the operating instructions of the manufacturer concerned.

Synchronizing with the transmitter is needed only once upon the initial start-up. Multiple systems

at different bikes should be started successively to avoid undesired assignments of different

power2max powermeters and bike computers.

CAUTION:

In the case of a too low battery voltage, no performance can be measured. Such condition

will be signalled by a permanent lighting of the

power2max powermeter’s red LED.
