Introduction
Note: Please keep the aircraft in the optimal radiation range of the directional antenna at all times.
Note: 1. Charge the battery with the USB adapter (Voltage: 5V+0.2V Current:＞2.0A) when you use the
USB charging function.
2. The lower the initial charging voltage, the better the charging effect is when the voltage
difference cells exceed 50 mV between the two.
2S Li-battery balance charging via USB-C:
The Green LED indicator states:
Led on: in Charging/Led off: end of charge/flash: charge fault

The Tandem X20 is a pioneering dual-band radio transmitter, it drew on feedback and experience with previous
radios and adds many new features such as color touch screen, an ergonomic design that provides unprecedented
comfort in the hand. On the RF side, we have given it the powerful RF system , the TD dual RF system, which does
not simply reiterate the combined features of the FRSKY900MHz and 2.4GHz RF systems. The TD is characterized
by its true simultaneous dual-band remote control with telemetry, enabling incredible and unmatched end-to-end
4ms latency. This radio ships with Ethos, a completely new system that provides users with a powerful, intuitive, and
flexible experience that maximizes the fun of the hobby.
Step 2: Set the Channel Range
The TANDEM RF module supports 24 channels. the channel range is configurable, and it needs to be double
checked before use.
