To answer Professor Shadow's questions:
[Q] Is this the same set that lost the Day/Night key?
[A] Yes it is on the same set that lost the Day/Night key

[Q] Is this a display or non-display keyset?
[A] The keyset is a display


I guess I did not describe the question clearly.
Let me try again. We have a keyset with a display (699029). It has a feature code Function key that was programmed to "Voice Mail". When we got a voice mail, the light/LED next to the programmed feature key would light up indicating that we have voice mail message waiting. We then proceeded to pushing the voice mail feature key to retrieve the voice mail messages. Now, the light/LED next to the voice mail programmed feature key would NOT light up any more when we get new voice mail messages. So, the voice mail system is still working because we can retrieve all our messages but the light/LED next to the programmed feature key no longer lights up.

I believe that all I need to do is to some how reprogram something??? so that the voice mail light/LED on the handset is lit when there is a new voice mail waiting.

Thank you. Ken.
