My office phone is a NEC DTU-16D-2 and the manuals have all been lost. I have a webinar that will require that I mute the phone. How do I activate the mute feature?

Yes, the NEC DTU-16D-1A can be used with a standard PSTN line. You will need to program the phone system to recognize the PSTN line instead of the ISDN2 line. Here are some steps you can take:

1. Access the programming mode on the NEC Xen Alpha system by pressing "Speaker" and then "7" on the main phone.
2. Enter the system password, which should be provided in the user manual or by your system administrator.
3. Press "Speaker" and then "3" to enter the line programming mode.
4. Scroll through the line options using the arrow keys until you find the option for PSTN. Select this option.
5. Save your changes by pressing "Speaker" and then "Store".

Once you have completed these steps, your NEC DTU-16D-1A handsets should be able to connect to the PSTN line and function properly.

Press Feature and then 1. This will turn on the MIC.

Would you expect a Nortel phone to work on an NEC sysem? The phone is digital and it requires an NEC system to work. Nortel M7208,7310, T7316 are phones that typically work on Nofrtel digital systems. They also require a digital port.

The phone model is not enough information.

Please leave a Helpful or FixYa! Rating. Thanks!!

Woo Hoo! I figured this one out on my own!

However...WARNING! I wouldn't recommend doing this unless you are technically savvy, as one wrong move could totally mess up all of your phones!!!

I searched and downloaded the Programming Manual from here: http://www.nec.co.th/html/download/Manual/Programming.pdf.

This manual will not only tell you how to fix this issue, but how to pretty much fix/change all programming for the NEC Electra Elite DTU-16D-2 phones.

I have also searched and downloaded the Feature Manual from here: http://www.nec.co.th/html/download/Manual/Features%20&%20Specifications.pdf

Happy Programming! =)
