Norstar M7310 call interuptions due to wrong time in display

[Lorilee541]

We had a power outage at our motel and tech support is out for the weekend. Does anyone know how to correct the time so we can recieve calls? We can call out but guests and office can not recieve calls. Help! I'm losing business!!
