I bought a new Standard Horizon GX1300 and finally got an mmsi number. I go to input my number and the vhs doesn't have "0" as an option, it goes from 1-9 only for my first number, and my two starting numbers are 0... The manual doesn't mention anything about 0's, but shows 0 in an illustration. I figure someone else on here must've ran into this before so I'm looking for any answer how to do this. The SH help phone number is closed right now so no help there as of yet.
