Sorry for the necro, but I investigated a bit, if the function could be restored, which it could not by any easy means. Wiring up the connection to any of the existing buttons messed with other functions. So I just drilled a small hole in the battery compartment and ran a wire from there to the I5 point. Now I can switch between 12/24H whenever I change batteries, without having to open the cover again.
