RDP 139 ROM error

Hi,
My 1833C can get the target well but it shows the ROM 1&2 error. What is happening with my radar? Will I can use it ?
Thank you
Nick

It looks like the memory on the main board has gone bad and the SPU board would require replacement. I doubt the radar would work but it won't explode if you try it.

Thanks so much for your help. I will replace the memory battery
