Pair 12-speed Wireless Di2 Shifters
I'll show you two different methods of pairing 12-speed Di2 wireless shift levers - using the mobile app and using wires.
Shifting Switch - I-SPEC
Deore XT SW-M8250-IR
The XT M8250 SHIMANO RAPID ES shifter feels instantly natural out of the box, but can also be molded to fit any hand, thanks to its familiar fit and evolved adjustability design. Multiple shift modes, like hold-down multi-shift, tactile click-through double shift, or locked-out single shift, deliver precision, while a tunable third button allows for additional system tuning or third-party connection.
This is a wireless shifter, powered by two CR-1632 batteries.
You can pair these shifters using the mobile app, by scanning the QR code - or even without the app.
Note that the without-the-app method only works if your derailleur has no shift units paired to it yet. Here is a quick video on unpairing and then pairing a 12-speed wireless MTB shifter:

These shifters do not have any E-Tube ports, and their firmware cannot be updated (according to Shimano).
