  • A lane is not showing in the ShootmasterII software.
  • A lane does not accept disciplines.
  • A shooter is attributed to a lane via the ShootmasterII software. The lane does not accept the shooter. ESTA5 does not show the name of the shooter.
  • A lane cannot be switched to match mode
Troubleshooting

Verify the following points.

Test your shooting range extensively after each point.

Re-establish the changes for each point before testing the next point. Repeat the changes of the preceding point.

Maintain a list of the changes. You can reset your shooting range after the troubleshooting.



Does the error disappear after switching off and on the devices?

Check if switching off and on the devices rectifies the error.

Perform the following actions:
  • Switch off all devices, then switch on all devices again
  • Switch off all devices, then switch on all devices again in a different order
  • Switch off all devices, then switch on all devices again while waiting 1 Minute between devices
