After turning on the ground penetrating radar, if the power indicator light is not on, please fully charge the battery first. If the computer is connected to the radar for the first time, it is necessary to set the computer's network: IP address: 192.168.2. X (X is any value from 2 to 254) Subnet mask: 255.255.255.0 Default gateway: 192.168.2.1 DNS: 192.168.2.1 Wireless connection requires manually connecting the computer to the radar network, setting the computer's network password to gpr123456, wireless security type to WPA2 Personal, and storing network information on the computer. When the radar is turned on again next time, the computer will automatically connect to the radar. When using the software's "normal" and "advanced" network detection to determine if the network is normal, if the network is still unavailable after 5 minutes, please check if the battery is low or restart the radar. When setting parameters, if the word "failed" appears, please reset. If the same problem continues to occur, please turn off the radar power switch and turn on the radar again after 10 seconds. The maximum number of echoes from the radar is 50000. When conducting measurements, please pay attention to the current maximum echo number displayed in the software information bar and save the data in a timely manner. The shortcut key to stop radar data collection is the "Space" key. If data collection still does not stop after pressing the "Space" key, please press the "Space" key repeatedly until data collection stops. If the problem is still not resolved, please contact our after-sales service at 027-67848802.
