57.6K baud. This will immediately change the baud rate of the CellScale. It
will transmit “When you can read this, press any key.” Change the baud rate of your terminal program to
match. Until you do the message will be garbage characters. When the message is legible due to matching
baud rates, press any key to return to the main menu.
This process completely destroys 9750A setups and erases data logging memory. It does
not affect CellScale calibration in any way.
