connect the battery unit cable into the BATT terminal of the power unit. Check that the termi-
nals of the battery connector and the battery unit are connected correctly.

• Engage the smallest gears at both front and rear so that the tension on the chain can be

minimized.

• Carry out calibration with the gear crank facing downward.

• Do not touch the crank during calibration.

If the setting is tur mned on, calibration starts to check whether or not the power unit is connected. After
calibration has been completed, the software of the main unit is available for the power unit.
Turn on Power select as this option is OFF by default.

NOTE:

• If the original menu screen reappears after an

“Error”

message is displayed, this means that the

power unit is connected incorrectly, or that the user is rotating the pedals during calibration.

• Even if an error occurs and Power select fails, the power unit is available for the main unit. In

this state, however, you cannot measure the power correctly. Specify the Power select option
again to complete calibration.

• If the power sensor has been used for an extended period, power-related values may shift and

affect accuracy. Make sure to carry out calibration periodically using the Power select option
on the main screen. Before important measurements especially, it is recommended that cali-
bration be carried out.

Wheel selection

You can choose between two wheels, A and B.
The initial value for tire size (circumference) B is 2050 mm.

NOTE:

• Before Wheel circumference, it is necessary to stop the measurement and reset all measured

data.

• Not resetting all measured data causes the

“PLEASE rESEt”

message to be displayed, making

selection impossible.
