 === Introduction ===
 Congratulations on your purchase of the '''KAVAN R8''' advanced 8-channel telemetry receiver. It operates on a 2.4GHz simultaneous dual-frequency transmission system '''Twin 2.4GHz'''. It has 8 high-precision PWM channels and 16 or 24-channel modes using S.BUS. Two detachable antennas with IPEX4 connectors provide full signal strength over a range of up to tens of kilometres. It is especially ideal for gliders, but you can also use it for other various models. With redundancy support, it can be connected as a primary receiver via S.BUS. With the '''Twin 2.4GHz''' protocol, both receivers work fully simultaneously in this connection. Thanks to the F.BUS connection option, you can also pair it quickly and easily to several different telemetry devices, providing bidirectional data transmission via a single cable.
