Note: Autocalibration by Serial Command is useful for quick calibration; however,

to do autocalibration and save your settings to the Configuration Database, or to

make changes to related parameters, see “Autocalibration by ESP” on page 6-4 or

“Autocalibration by Embedded Menu” on page 6-8.

Note: A user can abort autocalibration at any time by pressing the ESC key on the

terminal. No other keystroke has any effect while in Autocalibration.

Saving for Power-up

To save focus, tracking, and gain settings changed in Autocalibration for power-up,

send <Zp>.
