Mars 400S Pro Support

The casing of our devices was made of metal, so the inside circuit will not be interfered by other wireless signals. Normally the power of the walkie-talkie is always huge which could affect the transmission if the HDMI/SDI cable shielding properties are not good. Please try to replace an HDMI/SDI cable which has a good ability of anti-interference, and keep the walkie-talkie at least 1m away from the cable.
