Pro Timing is currently working with Sam to get the CP 540 back in operation again.

Remove batteries, reinstall batteries, press reset button with unfolded paper clip.

Try to restart, if ok proceed.

If not then updating the firmware using the two step process is needed. The older bootloader has to be used first, then the newer.

This can be done on site but it is better to return the unit to our service centre. 

During my last race the CP540 (system B) died... I was unable to restart it.

I removed the batteries and wait till the next weekend, than I replaced the batteries and resetted the timer. It restarted normally...

Now, do I need to update the firmware? Actual version is D-05...
Can it helps to avoid unwanted shut off?

Thanks for you advise
