Important Notes

1. This adapter provides charging function only — it does not support data transmission.
2. If using a non-original battery that has been deeply discharged, you may need to activate it with the original charger first.
3. If electronic shifting does not respond after charging, press and hold any shift button for 2 seconds until the indicator light comes on — shifting should then function normally.
4. Colors may appear slightly different due to monitor settings and lighting. Allow 1–2 cm measurement tolerance due to manual measuring.
