I have just received my new Flex 6600. Switched it on with a green flashing light on the power switch. This turned into a flashing red light, like a letter O and despite loads of attempts, that is how it remains. Any ideas? 73 de Roger, G3LDI

How many times is it flashing? If you count the flashes and look in the hardware manual it will tell you what the fault is.

I am guessing the letter O means three?
One red flash: Fan malfunction
• Two red flashes: Software crash
• Three red flashes: Boot failure
I get Two guaranteed every time I go on CW at over 80 watts and don't hit the ATU no matter what the SWR is prior to hitting the ATU.

The OP stated it flashed "like a letter O" so that would be 3 flashes and according to previously posted information, that indicates a boot failure.  Time to open a Help Desk ticket.

Roger, have tried a cold reboot? I have a 6700 so the procedure is probably different, but it will be in the manual. Something like holding the power switch until the rig shuts down completely, remove power for 60 seconds, replace power and turn the rig back on

Otherwise, as Greg mentioned, time to open a Help Desk ticket

Good luck Winston

Try disconnecting power cord from the radio 20 seconds then plug it back in and try again.

I guess I skipped a couple of critical points.  Yes, a complete power disconnect for 20-30 seconds, then reconnect and restart.  A factory reset can also be tried.  If all that fails, go to the Help Desk!

Hi Roger,

I have the same symptom with my recently delivered 6600 - opened a Help Desk ticket this afternoon.

Were you able to resolve the issue in the field or did you have  to send it back to Flex?
