Steve,

I had to do this when I switch from EC2 to EC3. This was Tracy's instructions. I don't believe this was published in any of the documentation.

"Do the power up program in mode 5,  Coldstart sw UP

Power off on EC3
set Mode 5
set CS switch ON
Hold Store switch pressed
turn on power to EC3
Wait 2 seconds and release store switch.
Power off.
set CS switch off
set Mode 0"

Hi Guys

I found the notes below embedded in Tracy’s code notes:
It would seem that Mode 5 enables us to switch between a WB & NB O2
Does anyone have documentation that reflects this or can confirm this?

Cheers
