Using the Hollyland Cosmo C2 is a breeze. First, power up the transmitter and receiver. You can use the specified batteries or DC power supply as mentioned in the technical specs. Connect your camera to the transmitter using either the HDMI or SDI port, depending on your camera's output. Then, connect the receiver to your display or recording device in the same way. For live streaming, choose the appropriate streaming protocol like NDI HX3, UVC, or RTMP. When setting up multiple cameras, the dual - transmitter and single - receiver configuration makes it easy. Just connect each camera to a different transmitter. Keep in mind that the line - of - sight range is important for a good signal. Try to keep the transmitter and receiver within 3,000 feet (1,000 meters) of each other. Avoid using the system in areas with a lot of interference, as the frequency hopping feature may not be able to compensate fully. When it comes to maintenance, keep the equipment clean. Use a soft, dry cloth to wipe the devices. Don't expose them to extreme temperatures or moisture. If you're not using the system for a long time, store it in the provided carry case. Check the batteries regularly and replace them when needed. And always refer to the user manual if you have any specific questions or run into issues.
