USB cover Check to see that the USB cover is seated properly!
7.2.2 Pair your head unit with your power2max power meter
Pair your Ant+ or Bluetooth enabled head unit with your power2max NG power meter. As long as the
green LED indicator light blinks, the power2max NG power meter is emitting signals that can be
received by the head unit. Observe the respective manufacturer’s manual. Pairing your head unit is
only necessary when operating the power meter for the first time. However, you can repeat the
pairing of your ANT+ or Bluetooth-compatible head unit at any time. To do so, you just have to
activate your power2max NG power meter by turning the cranks. Your power2max NG power meter
then signalizes its availability for pairing by blinking its green LED indicator light for one minute.
Please note: Different power meters on different bicycles should be put into operation one after
another to avoid unwanted connections between the different power2max power meters and your
head units.

7.3 Head units
You need an ANT+-enabled head unit that supports the power-only profile (PWR). For example,
suitable head units are:
CYCLEOPS: Joule 2.0 and 3.0
GARMIN: Edge 500/510/520/800/810/820/1000, Forerunner 310XT/910XT
O-SYNCE: navi2coach, Macro X and Macro High X
Wahoo: Elemnt
You can find a current list of compatible products at the ANT+ Alliance:
http://www.thisisant.com/directory/power2max-road-rotor-3d-plus-bcd-110-or-130/
The data for power, cadence, left-right distribution and smoothness are calculated and transmitted
via ANT+.
In addition, your power2max NG power meter offers the option of using a Bluetooth low-energy
compatible display instrument (BLE) that supports the Cycling Power Profile.
7.4 Installation of your power2max NG power meter on your bike
7.4.1 Chain ring installation
1. First install the chainrings on the power2max NG power meter. In the process, take care that
they are aligned correctly and solidly attached in accordance with the respective
manufacturer’s specifications. Guide the large chainring from above onto the power2max NG
power meter.
2. Align the holes for the bolts.
3. After you have guided the small chainring onto the power2max power meter from the rear,
tighten everything with the dedicated chainring bolts.
IMPORTANT: Observe the torque values prescribed by the manufacturer.
Pay attention to the alignment of the chainrings and bolts. Please adhere to the manufacturer’s
specifications.
7.4.2 Crank Installation
1. Mount the crankset to the power2max power meter.
2. Guide the right crankarm from the front through the opening in the power meter. Pay
attention to the alignment and the correct fitting of the crankset to the power meter.
3. For models with lockrings (e.g. Cannondale Hollowgram, FSA BB386evo, Rotor 3D24, Rotor
3D30, Rotor 3D+ or Specialized S-Works): place a few drops of medium-strength threadlock
(e.g. Loctite 243) on the inner side of the lockring and tighten it with the help of the Lockring
tool. PLEASE NOTE: Pay attention that the lockring is seated properly on the thread. Lock the
lockring tool into a vice. Doing so, you can make sure that the lockring tool is secure and
stable for further installation.
4. Tighten the lockring to the prescribed torque values
5. For models that are installed with threads (e.g. FSA Megaexo, SRAM Force22/S900): place a
drop of medium-strength threadlock on the installation bolts. If threadlock has already been
applied at the factory, then you can skip this step. Tighten the installation bolts to the
prescribe torque values. You can also find these values in the download area on
power2max.com.
Install the entire crankset to your bicycle. To do so, follow the steps in the installation
instructions provided by the crankset manufacturer. If necessary, these can be requested
from the crankset manufacturer or from a retail store. We recommend checking the correct
function of the front derailleur and, if needed, re-adjusting it.
IMPORTANT: Observe the installation instructions prescribed by the manufacturer.
The initial operation and installation of your power2max power meter is now completed.

8 Using your power meter
Using your power2max NG power meter is as easy as the initial operation and installation is.
8.1 Before your ride
When your bicycle isn’t being used, the power2max NG power meter is in standby. When the crank is
moved, the power2max NG power meter is activated automatically, and the power2max NG power
meter begins emitting a signal. This is shown by the blinking of the green LED indicator light. At first,
the LED indicator light shows the battery level and then its availability for a connection to a Bluetooth
low-energy compatible instrument (see also 15: Technical specifications, LED signals).
8.2 During your ride
Your power2max NG power meter updates the metrics of power, cadence, left-right distribution
(balance) and smoothness in 1 second intervals; they are then transmitted per ANT+ protocols or
BLE. In the case of BLE, torque data is also available.
8.3 Zero-point adjustment and thermal correction
To ensure a precise power measurement, the zero-point (the measured value when no torque is
present) is automatically determined by your power2max NG power meter. The zero-point
adjustment compensates for influences caused by temperature variations and mechanical zero-point
shifts. It is possible to repeatedly set the zero point at the head unit, but it isn’t necessary! This is
performed by the system automatically when it is not under power. “Not being under power” means
a stop in pedaling for at least two seconds during a ride. If a de-powering as described above is not
possible, for example during a long mountain climb, then your power2max NG power meter
automatically compensates for temperature. Thus your power2max NG power meter guarantees a
reliable power measurement.
IMPORTANT:
In the case of track models, the automatic zero-point adjustment is deactivated. You should regularly
perform a manual zero-point adjustment with your head unit.
8.4 Battery life
Battery life is approximately 150 hours. Battery life can be decreased by low temperatures and by
transporting your bicycle, for example in your car.
8.5 After your ride
Your power2max NG power meter independently enters standby mode approximately two minutes
after ending your ride.
8.6 Charging the battery
Please follow steps described under 7.2.1 to charge your battery. When charging is completed, the
LED Indicator light blinks red.
8.7. Battery charge level
Directly after activation / waking up your power meter:
3 x green: battery charged 60 - 100%
2 x green: battery charged 40 - 60%
1 x green: battery charged 20 - 40%
1 x red short: battery charged 10 - 20% (equates to "weak battery")
1 x red long (5 seconds): battery charged 0 - 10%
Please note: To protect the battery from damage, it automatically shuts off when it goes below a
minimum capacity.

8.8 Turning the power meter on and off
1. Turn it off: Plug the big end of your USB cable into the charging unit. Open the USB port
cover on the power meter, plug the small end of the USB cable into the USB port and remove
it within two seconds again!
2. Turn it on: Plug the big end of your USB cable into the charging unit. Open the USB port
cover on the power meter, plug the small end of the USB cable into the USB port and wait
until the green LED indicator light turns on. After approximately five seconds, the red LED
indicator light blinks (charging). Then the power meter is turned on.
Please note: When transporting your bicycle, the power2max NG power meter is activated.
Therefore, it is recommended to turn off the power meter for longer transports. You should
generally turn it off when transporting your bike in a plane.
8.9 After a crash
As a spider-based power meter, the power2max NG power meter is located in a place where crash
forces are usually completely absorbed by the crank and bottom bracket. Therefore, crash damage to
a power2max NG power meter is almost impossible.
In the interest of your own security and health, you should do the following checks after a crash:
1. Please check if the crankarms have sustained any damage. (The crankarms could suffer from
hairline fractures that you may eventually not recognize at first glance, but which could
result in sudden failure over time. Therefore, replacement is recommended.
2. Please check if anything is rattling around the crankset or the bottom bracket. This can be an
indication of damage.
3. Examine all mechanical connections.
9 Maintenance and care
1. The USB cover should be checked occasionally to see whether it is seated correctly and, if
necessary, it should be replaced so that the USB socket maintains its waterproof seal.
2. After longer rides in the rain, please examine if water has penetrated the USB cover. Should
this be the case, allow this area to dry out while the USB cover is off. You can assist in this
process by using an absorbent cloth.
3. Do not use thinners or solvents to clean your power2max NG power meter. Use clear water
or soapy water and a soft sponge or rag.
4. PLEASE NOTE: Do not clean your power meter with a high-pressure power hose!

10 Disposal
The symbol of the crossed-out garbage pail on wheels, which can be found on the product, the
documentation and the packaging, means that electrical and electronic products, batteries and
accumulators need to be discarded separately in the European Union. Do not dispose of these
products in general household garbage. Separate these products from other garbage in order not to
damage people’s health or the environment due to uncontrolled garbage disposal and in order to
promote sustainable recycling of material resources.

11 Service calibration and control of function
The power2max NG power meter is calibrated at the factory and doesn’t have to be newly calibrated
within the warranty period. Regardless of this fact, you still have the option of ordering a calibration
and function control in our Web Shop. In this case, we will examine your power2max NG power
meter on the outside, perform a new factory calibration and control of function. In addition to your
power2max NG power meter, you also receive a new test and approval certificate.
IMPORTANT: Ordering a calibration and function control can be advisable after a crash, among other
things. However, it does not extend warranty coverage and only excludes a possible liability resulting
from mechanical damage that has not been identified.
