TTI 1604 - Calibration; Calibration Settings and Adjustments

Calibration
Only the case upper needs to be removed for calibration; the screens should be kept in place.

Accuracy of frequency measurement is determined by the CPU crystal which has greater
accuracy than the display resolution and therefore does not require calibration.
