Refurb LDP-9030D UK base unit won't boot on IPECs

[gamesgenie]

We have a US IPECs system with LDP-9030D base stations. Some of the basestations have various issues accrued from just daily use that cleaning alone won't address, so I picked up some refurb 9030D base units from a reseller in the UK thinking they would just plug and go like the ones we have, and that is not the case. None of them will power up when plugged in to the phone jack. Is there some configuration or dip switch I need to set so it will work with our US IPECS system?

If it is from UK the line socket maybe wired not as in US .

I guess I can take apart an existing base station and these refurbs to see if the wiring from the RJ11 jack goes to different places in the phone or in a different order. I made the mistake of assuming that the IPECs would be sending out the same way on the same models, no matter where they were, but maybe the UK is somehow different? I was hoping someone knew the answer offhand...
