Motorolla HT1250 Programming manual
You can also search the help section built within the software.
In the Basic Service Manual (which is already uploaded here) there is some more setup information from Chapter 5. That will guide you on connections and programming equipment.
Motorola used to make those gigantic programming manuals for everything..but I'm pretty sure they didn't for the HT series radio. The help menu has all the information you need.
