FrSky TANDEM X20 PRO Instruction Manual

Introduction
TD-ISRM PRO RF PERFORMANCE
With solid performance based on the dual-band 900M/2.4G RF signal link with multiple operating combinations
of RF modes, the TANDEM PRO continues to break new ground in RF performance. The X20 PRO added the
dual 2.4G TW RF mode and supports simultaneous activation of both TW and ACCESS R9 modes. In this
configuration, TW receiver and ACCESS R9 receiver can be connected via the SBUS IN/OUT ports to achieve
redundant backup. This RF signal connection method allows for the simultaneous use of three different RF links
in RC applications. This further enhances the RF signal's reliability, particularly in scenarios involving long-dis-
tance RC operations.
COMPREHENSIVE FUNCTIONAL INPUTS & SOLID-QUALITY METAL PARTS
The X20 PRO optimizes and integrates the functional inputs of the TANDEM series models. Building on the
foundation of X20/X20S, it adds 2 extra trims, allowing for more precise tunings during the operations. The levers
on both sides of the transmitter's slider support customizable positioning of the center toward, catering to different
users' habits and preferences. Additionally, on the left and right sides of the handle top of the X20 PRO, one
self-locking switch is set on each side to prevent accidental triggering of the Kill Switch, ensuring the safety of the
surroundings.
The main body of the X20 PRO is constructed with a all CNC-machined metal material, and the central panel
incorporates genuine carbon fiber material. The primary input components, including trim caps, slider levers, and
knobs, are all made from metal, offering rugged quality and enhanced durability for outdoor use.
BUILT-IN MASS STORAGE & TEXT TO SPEECH FUNCTION
In order to save the user the trouble of deciding the storage capacity, X20 PRO comes with a built-in 8GB flash
storage that offers plenty of file storage to meet all of your radio's storage needs, along with high data transmis-
sion speed.
Thanks to the upgraded storage feature, the TTS (Text-to-Speech) function of X20 PRO can quickly and
conveniently convert typed input English words into spoken speech. This enables the ETHOS system to more
flexibly match the triggered operational status using generated speech file when specific functions are activated,
and to alert clearly outdoors with the digital power amplifier module.
