• Unplug the HI-PRO power cable and plug it back in again firmly. Ensure the HI-PRO power light is on.
  • Check the serial or USB cable and ensure it is firmly plugged into the computer system and the HI-PRO.
  • Run a HI-PRO check which can be found in the Options > Preferences > Fitting Device > HI-PRO menu. Confirm the HI-PRO connection method reflects your current setup using the HI-PRO configuration button.
