To calibrate the cable to your device you must use the ShockAi App. Open the App, select the VoD-Mini you wish to calibrate.

Ideally, leave the unit on for around 5 minutes prior to calibration to let the unit get up to operational temperature.

Connect some cable, if you purchase cable from ShotTrack it will be very close standard.

Navigate down to the "Calibration" button and press "Edit"

Then enter in the length of cable you have. At the moment even if you have 305m you still need to change the value for it to update, so reenter 305 and press "Update" then "OK"

The screen will return to the main menu and the cable length will be displayed and is now calibrated.
