How do I turn the radio function on on my NEC Dterm Series 16 button phone ?

.. I don't have a solution, I need a solution.
NEC Dterm Series I, through internal calls my phone flashes notifying me that I have a call coming through but it doesnt ring. I have tried the volume key ^, that didn't work. Can anyone help me?

Try speaker 43 then 3000 speaker

Press Feature, press the button you wish to program, dial the number and press Feature.

This phone works on different NEC phone systems.Elite,IPK, 2000, 2400. Each speed dial code is different in each system. what system do you have

There is an access code to turn off MW lights.IT depends on what NEC system you have.

try caling your voicemail and leave yourself a message and clear all messages in box.

Yes thst is done in the Voicemail

with handset down press speaker and then #8

Thankfully I have found a solution that has worked.

A 'winking' (flashing) feature button indicates the station is in call forward - all calls mode.

To cancel this setting do the following

Lift the handset or press speaker
Dial the access code 4 + 2 (set as default)
Receive confirmation tone and restore handset or press speaker

I have found the manual at the following link to be the best resrouce ever - very easy to understand
