The message waiting light keeps flashing on the phones despite all messages being deleted ...how do I stop the light from flashing on the upper left of each unit??

Yes, the was bothering me for some time. I think the indicator is a little green light that blinks in the extreme upper left hand portion of the phone...not on screen, above it....but the blinking light may indicate a missed call or a voice mail is present.

Try this. Go into your phone icon, press and hold '1' and listen to any open messages. Delete each. Next go into your Call Log and delete all call history. Now exit.There should be no green light flashing in the upper left hand corner of phone. You have just cleared everything.

Next call your phone but hang up before leaving a message. Note the blinking green light in the upper left hand corner apparently indicating you missed a call. Go into your Call Log. It will say one missed call. Exit the call log and note that the blinking light is now off. You have acknowleged the call in the call log so the light goes off when you exit.

Call the phone again. This time leave a message. Note the blinking light again. Go into your call log again. Note the missed call. It would be nice if there was an icon or something HERE that indicates if this call left a voice message....but there does not appear to be. Exit again. This time note that the light continues to blink even though you entered the call log and acknowleged the call. I believe it continues to blink because you have a voice message. Exit.

Go into the call log again. Delete the missed call from the call hsitory. Exit. The light still blinks, I believe still indicating a voice message.

Go to your phone icone. Press '1' to check messages, delete the message and exit. The blinking is now gone.

So it appears a blinking green light indicates a missed call. If it still blinks after exiting the call log, you have a voice message.

If someone figures something else out let me know because this stinks!

Dear friend, You have not written about your model no. Yet if you are sure that you don't have any unread msg, then its happening because your msg memory is full! Please clear up your msg memory by deleting some msg's . I am sure deleting some msg will help you. Regards, Priyank Abhineet.

I had the same issue on my RCA 25255re2 and worked with customer service at RCA. They had me hold down the delete button for 5 seconds, release the delete button, then press delete one more time. That cleared the phantom L1 message waiting issue we were having at my office

I may have already posted a solution for you from another location. But if not heres what I said.
If you also have voice messaging with your phone company, you might have voice messages stored with them. If so you need to access it with your password to clear them. To find out if you do have voice messaging, call your phone company and they can let you know and reset your password if so. The phone companys voice messaging system sends out a signal that would cause youe phone to think it still has a message waiting.

The term we used for this back when I worked for the phone company was a "stuck message waiting indicator" and the way to fix it was:

Call yourself and leave a message.
Hang up and wait 2 minutes (we used to say 5 minutes, but 2 is plenty)
Retreive/delete your voice mail message
Hang up and wait 2 minutes


That should clear the blinking light.

The light in the upper left indicates you new messages. The light will flash until you clear all messages.

turn it off and take out the battery?
But it could be a software problem?

Don't know about other models, but I just called RCA small business phone support (800-511-3180) to find out how to clear the message light indicator on my 25210 2-line cordless phone when it continues to blink but there is no message.

All you have to do is hold down the delete button for a few seconds and it will clear. Hope this helps someone else from going batty!

Here are sample paragraphs from the user manual : hope it helps !

The new message LED on the handset flashes when you have new messages in your
answering system. The LED stops flashing when all new messages are played back.

3) To delete all messages, press delete messege in standby mode. Press delete
messege again after the announcement "To delete all messages, press delete
again."
When you try to delete all messages without first listening to your new messages,
you hear several short beeps followed by an announcement "Please playback all
messages." This protects you from accidentally erasing messages you have not yet
reviewed.
Important:
When you press delete messege, you are permanently deleting the message. Once
deleted, the message cannot be replayed or retrieved.
