D710 G TNC ERROR Message

Dennis Yard


My D710 has failed to open the TNC upon power up and gives me a TNC ERROR message.    I can't use APRS or PACKET again.  It was working last week.

This is the third time in about 18 months of ownership.   It was sent back the prior two times but the only apparent Kenwood action was to replace a keeper battery in the unit.  

Any suggestions?
