4.3. Calibration failure
The software does not display if the calibration routine has failed. To check calibration status use the CAL LED on the TONiC
readhead. If calibration fails restore factory defaults by pressing and holding the CAL button on the dongle interface whilst
cycling the power. See the relevant TONiC installation guide for details of the calibration routine and restoring factory defaults.
4.4. Pitch indicator failure
Ensure the readhead is not over a reference mark when checking the readhead pitch. If the pitch indicator ‘bubble’ does not
move on pitching the head or remains to one side of the centre unplug and reconnect the USB to cycle the power.
