This function allows the ID signal transmitted by the heart rate sensor to be received and checked.
Before ID check, attach the main unit to the power unit.

NOTE:

Be sure to attach the main unit to the power unit. Signals from the heart rate sensor cannot be
received by the main unit alone.

Within 5 minutes of pressing the START/STOP/ENTER button, place the HR sensor approximately 20-80 cm
from the main unit and press the reset button on the HR sensor for five seconds to transmit the ID signal.
When the main unit receives the ID signal, the ID check has been completed.
You can view the ID number but cannot reset it while the bicycle is in motion.

NOTE:

• Failure to receive the ID signal within five minutes or the pressing of the START/STOP/ENTER

button cancels the heart rate sensor ID set mode, leaving the ID as it was.

• When two or more users of this unit ride side by side with the same ID, interference can occur

which may, in turn, prevent correct measurement. In this situation, carry out an ID check again
according to the illustration above.

• When two or more users with this unit ride side by side with the same ID, interference can
