[RASMB] Perpetually "waiting for speed"

[Karen Fleming]

We’ve had a lot of trouble with our XL-A this year, and the latest problem is that it is stuck at  “Waiting for Speed” and will not scan Does anyone know why it is stuck. It is indeed AT SPEED.

The other error we are getting is RTE not running checksum error. What is this and what do we do about this.

We’d really love to resolve this ourselves so we don’t have to call Beckman service.
Thanks, 
Karen Fleming
