1.
Install the battery.
2.
Shift the rear derailleur to the 5th sprocket position.
Press the button at the junction (A)
of the SM-EW79A until the red LED
turns on in order to switch to rear
derailleur adjustment mode.
Note that if you keep pressing the
button after the red LED has
turned on, protection recovery
operation will begin.
* Refer to the Service Instructions for the rear derailleur for details
on the protection function.

If shifting switch (X) is pressed once, the guide pulley will move
one step toward the inside.
If shifting switch (Y) is pressed once, the guide pulley will move
one step toward the outside.
The guide pulley can move 12 steps inward and 12 steps outward
from the initial position, for a total of 25 positions.
When adjusting, the guide pulley will overrun slightly and then move back in an exaggerated movement so
that you can check the adjustment direction.
When checking the positions of the guide pulley and the sprocket, check at the position where the guide
pulley finally stops.
