Hi,

there is only are three ways to reprogram:

1. Service Laptop with JUDIT (Jungheinrich technicans only)
2. Hand Lisa (You eventually can buy that tool from TVH in Belgium)
3. If you have an Jungheinrich EFG-DF or EFG-V which is the same machine then you can switch the Display from the Jungheinrich on the Boss and with that you can reprogram.
