Hi, we have an NEC Electra Elite 192 using DTU-8D-2 handsets. I need to enable an extension to ring when in day mode. Does anyone have a pointer to the exact key sequence to do this on the handset?
Thanks.

This is accomplished within system programming under memory block 4-1. Ringing is assigned on a station port basis (meaning if you're trying to make extension 105 ring, you need to verify that station 105 is station port 06 in system programming).

You have to make sure that no Ext. assigned to DIT mode for Day and Night before you doing 4-1.
