    Can you tell me how to changes the time on our NEC Dterm 80 phone system? We changed time on Sunday and I need to update.

    I agree with the other user. I did what the instructions said and it didn't work. (9 and #) and by the way (9 and hold) doesn't work with this phone system either.

    Press Feature and then 9#
    Press # to select each number and the AM/PM
    Press Feature when you are finished

Press the "Speaker" button and enter 728 on the key pad. Then enter the correct time in 24 hour format. For example at 2.56 p.m. type 1456. Then press speaker again and you're done

You have to find the phone that was specified as the admin phone in the office and change it on that phone. All of the other phones will change automatically. You press feature, then 9, then #. Change the time, then press feature again.

Press feature # 9 use up and down arrow keys to change the time and then press feature again and your time will be set on the phone

Dterm time is controlled by the NEC phone system software. Because it is proprietary software, it does not sync with an external time server but runs off of the system's internal clock. Have your telecom support personnel use the ATIM command from the MAT interface and adjust the time.

Need to change the date on a NEC Dterm80 phone. Feature 9#hold didn't work for me. I normally use the Speaker - 728 - to change the time.

Feature 9# has to be done fromt he Admin phone. Somewhere on the system there is a phone that is the Admin phone.

I have the 8 button phone and if you hook up your headset the right way you just have to press the line/feature access key all the way to the right instead of picking up the receiver. Keep the headset on all the time and just press that button to answer or hang up the calls. It works great! ( I have the Dterm80 telephone)
