6500 ERROR message on startup.

Hi Harvey: If this was a one time event, I would just keep going. If it happens on a recurring basis, the radio may need to come back for warranty service. What the message means is that the internal power supply monitor and sequencer (called a PSoC) saw a voltage of 5.88 Volts on the 5.3 Volt power distribution rail, and chose to go into shutdown. The unit should have shut down operating, shut off all fans, and stopped communicating with the controlling PC, but the blue front panel display (which is under control of the PSoC) will remain lighted until the radio is power cycled. --- Graham / KE9H
