Message light on PanasoicDT 343 phone 1

[MikeinTx]

I have a customer with a Panasonic TDA 50 phone system and a TVA 50 voice mail. One user has a DT343 phone and I can't get the message light to go out. No new messages and 3 old. Any ideas on why the light won't go out?

Thanks

With handset down press message button. Then press clear. Or dial *700 and its own extension numbet

Dialing *700 and the extension number worked. Thanks for the help.
