Check your power supply voltage. 4 red flashes indicates an overvoltage condition.

If the voltage is in spec (13.8 VDC +/- 15%), you should probably submit a help desk ticket.

When the red LED on the front of a FLEX-6400/FLEX-6600 blinks four times, it is an indication that the voltage input to the radio is over the threshold (16V).  Power control will remove power from the  radio and wait for a restart.

You need to check your power supply voltage.
