Using the soft buttons at the bottom of the display, click the last button on the right (More). This will provide another set of options. The third option from the left should say "DND". Press the soft button below this option to turn off DND.

You have the button wrong. If DND is on, the phone will not ring.

pickup the handset (phone... watever) and press the FWD/DND button then press #2 then type in the number of the mobile (or number you want to forward to...), and hang up the phone... then when your finished with the call forwarding function, press FWD/DND again and this time press #0

What 2 does it turn on the call forwarding feature
. and 0 turns off forwarding/do not disturb functions

theres 5 different functions after you press FWD/DND

0: turns FWD/DND off
1: put the phone into Do Not Disturb Mode
2: call forwarding
3: Busy-Forwarding.. which means if your on the phone and someone rings, it forwards them to the number you specify
4: No Answer- when you don't answer the phone if forwards the caller onto the number you type in
and lastly 5: Busy/No Answer- does both function 3 & 4

i hope i've helped

I loosely followed Solution #2's answer. If you pick up the phone, the display screen will show options above each of the 4 'arrow' buttons. The one to the far right, for me anyway, showed something looking like this: >>>

I hit it and it showed a number of options, one being "DND". Hitting that deactivated (or activated) DND on the phone I was currently on. That solved the problem for me.

Please contact your local NEC dealer and have them program the phone to go to voicemail when in DND or when Busy

It sounds like you have enabled Do No Disturb accidently. This can be turned on and off by pressing the DND softkey button along the bottom of the LCD display. You might need to press the 'more' softkey to display all options.

There should be a button your phone that is lit green. Press it. It should go off.

OR, you can try to hit "FEATURE 01"

Press PROGRAM + ** + User Programming Password (default is 1234)

Press 000
Press NEXT (Sp-phone button) : The date will be displayed.

To change the DATE (or you can press next again to go straight to change the TIME)
Enter the year (last 2 digits)
Press --> (FWD/DND button)
Keep pressing SELECT until the desired month is displayed
Press --> (FWD/DND button)
Enter the day
Press --> (FWD/DND button)
Keep pressing SELECT until the desired day of the week is displayed
Press STORE

To change the TIME
Press NEXT (Sp-phone button): The time will be displayed.
Enter the hour
Press --> (FWD/DND button)
Enter the minute
Press --> (FWD/DND button)
Press Select for AM or PM
Press --> (FWD/DND button)
Press Select for 12 or 24 clock hour
Press STORE (Auto Dial button)
Press END (Hold button) to exit

Another solution is to pick up on intercom and dial 4 then 2 and hang up. That is the default DND cancel code. It can be used form single line phones within the system as well.
