Subject: RE: Di2 ??? The lights are there for a few things. The main function that they will have for you is the charge indicator. Hold any of your shift buttons down for a few seconds and the lights will come on. Solid green means full charge, flashing green means 75%, flashing red 50%, solid red 25%. The other user function on the junction box involves the button on the box itself. Push that button and the red light comes on. This lets you use your shifter as a barrel adjustor to make fine-tuning adjustments to your rear shifting. If it's flawless right now I probably wouldn't push that button.
There are other functions of the lights on the junction box, but those are used in conjunction with the Di2 System Checker that your local bike shop should/may have. |
