Unzip the downloaded file, and click setup.exe to install the software, and then click Next to continue. 3.
Troubleshooting This part describes problems you may encounter while using the device. PC Communication Error If you cannot communicate the Scope Module to the computer, you need to do the following check-ups: Check if the USB connection is properly connected between the Scope Module and the PC. Check if the LED breath light on the Scope Module is illuminated. If the LED light is shimmering, this indicates that a communication error has occurred.
