M7310 does not have a red light.
And even if it did you answered your own question....you left that phone a message so now it flashes to let that person know they have a message.
F65 to see who left message
F#65 to clear MSG and/or light.

You have a phone with built in answering machine.

This flashing light means you have a message. Just listen to the message, and delete it, then the light will go away.
Perhaps there are many messages.
You need to listen to them all

from operators dss hit mw key then the ext you are trying to clear

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!

Press down the "find handset" button until the paging beep stops (about 5 seconds) and this will reset the indicator lights on the handsets.

I hope this will help. I had the same problem with the message alert light not turning off. I have phone service through the internet. I would clear messages from my base unit and alert would continue to flash. I went into my internet message center and found a few old messages there. Why they got there is beyond me, but after clearing them my alert light went out and stayed off. I disabled messages to internet inbox and now it flashes only when I get messages to my base unit until I listen or clear them. Easy fix to annoyance I've had for some time.

go to the phone where the light is flashing press intercom #409. you may have to do that more than once. Keep doing it until the light goes out.
If the phone system is a DK 8 orDk16 press intercom 409 this will cancel the message waiting light that could have been cativated by a different extension.
