with a smartphone/tablet.

How to make connections

ANT connection

To make a connection, the cycle computer needs to be in connection mode. For information on
how to put the cycle computer into connection mode, refer to the manual for the cycle
computer.

1) Put the cycle computer into connection mode.

2) ■When using an external battery
Check that the electric wires are connected to the system information display. Then, remove
and remount the external battery.

■When using a built-in battery
Check that the electric wires are connected to the system information display. Then, remove
the electric wires from the system information display and reconnect them.
(Connection transmission begins about 30 seconds after the battery is remounted or the
electric wires are reconnected to the system information display.)

3) This completes the connection process.

Check on the cycle computer to see if connection was successful.
If a connection cannot be made in the way described above, refer to the manual for your cycle
computer.
For information on how to show the number of gears or the DI2 battery level, refer to the
manual for the cycle computer.

About the RD Protection function

Rotate the front chainwheel while restoring operation after the RD Protection function has
activated.

In order to protect the system from falls etc., the RD Protection function will operate when the
rear derailleur is subjected to a strong impact. The connection between the motor and the link is
momentarily severed so that the rear derailleur will no longer operate. If this happens, press the
mode switch for 5 seconds or more. This will restore the connection between the motor and the
link, and clear the RD Protection function for the rear derailleur. If recovery cannot be
performed through switch operation, manual operation is also possible. Consult with a
distributor in advance.
