ok. well we got a buidling a while back and would you know it came with this coral 2 phone system. the modle number is 440840610. But i am having some problems. first i will ask just some jeneral questions. On the sys. there is the power input. so it is pt13 sgnd, pt12 +vin, and pt11 -vin. I think it is just + - and ground but can some one clear how i should connect it. Next on the two power converters. the rps and pps. there are eather a tp1, tp2. and rtn. What does they mean? also the adjustment screws, are they for power or what? i sope some one here can help
